After you plug in the SIM card, you have to power it up again.Step2: Connect 1x 4G sucker antennas and 2x WiFi antennas to the identified interface.Note: you can just connect 1x 4G sucker antenna to Main 4G interface, AUX interface isa auxiliary interface can be disconnected under normal circumstances without affecting thereception and transmission of 4G signals.Step3:Conncect to Power adapter into the router.Power LED ONWIIFI LED ON When the router os start finished3G/4G LED fast blink means have register mobile networkNote: Usually, you don't need any Settings to get online. However, if you are a special SIM card, you need to set it according to the APN provided by the supplier.2.6 Indicator light description This 4 g router is provided with the following signal indicator lights, according to "PWR", "3 g / 4 g","WIFI", "WAN", "LAN1 - LAN4"Signal strength display: Defines as follows ：LED Status DefinitionPWR OFFNo power is plugged in, or the machine is damaged Normally on The power input is correct and the machine is energized3G/4GNormally on Not registered to 3G/4G networks Quick flash Registered to 3G/4G networks Slow flash Not registered to 3G/4G networks WIFI Normally on SYS have ok, wifi have workingNormally flash The WiFi client connects successfullyand has data interactionWAN OFFWAN port cable not inserted (generally used for broadband line access)Normally flash WAN port cable insertion with data interactionLAN1-LAN4 OFFNo cable is inserted at the corresponding LAN port Normally flash The corresponding LAN port has cable insertion and datainteractionRESETPress up 5s then release to go to factory settings, you will see “wifi” led will off then ON. Mean to its successfulNote: How do I know if my router is working? Since the router works on the LINUX operating system, the PWR indicator will be on at first after the power is turned on, then the router system starts to start and the 4G network starts to work. After the startup is completed, the WiFi light will always be on (it will flash when there is data to send or receive), and the 4G/3G indicator light will flash, which means that the 4G router works normally and you can surf the Internet without any Settings.3 Configuration Parameters3.1 Prepare for router configurationAfter the hardware installation is complete, you need to make sure that the management computerhas a network card or WiFi network card installed in front of the Web Settings page of the login router.3.2 Via LAN port login the router for setup or internetConnect the yellow network cable to the router's LAN and the computer's Ethernet interface, then find the network and sharing center in the computer-control panel, click the local network connection and click properties:SLK-E900-LTE default IP: 192.168.2.1, setup the computer of local ip as 192.168.2.x(x is 2—255)Manually modify the IP address as shown in the figure below, or click to automatically get the IP address automatically allocated by router DHCP.Note: if want to through our 4 g router to the Internet, the default Gateway and DNS need to changeto 192.168.2.1 as below:3.3 Log in to the configuration page of the routerNote: using Google browser or A browser with A kernel over IE10.Default password: admin, no name required.3.4 Via WIFI to configure the router or get internetAs shown in the figure, open the Control Panel - network and internet-network connection, select the wireless network connection, and click connect to. Find the router's SSID and enter the defaultpassword to connect to it. The default WiFi password is on the back of the router. The connection is successful, You can then configure this by entering the router's IP address in the browser. For SIM CARDS that do not require configuration, you can access the Internet as long as the WIFI connection is successful.3.5 Via Mobile Phone to configure the router or get internetO pen the wireless local area network (WLAN) search to the router's SSID, begin with SLK - Routers, by default the WIFI password on the back of the router. After entering the password, you can access the Internet or enter the router IP address in the browser for configuration.Click the position of the logo once and the configuration interface will pop up from the left side:3.5 Modify router default IPLogin the router - network - interfaces – LAN -EDIT - IPV4 addresses, change the ip to you want.3.6 Change the WiFi password and ESSIDLogin the router: Network- WiFi - EDIT - wireless security, changes the WIFI password Login the router: Network- WiFi - EDIT - ESSID, change the WIFI SSID3.7 APN settingsNote: Most of the world's operators allow access to the Internet without any APN, but some special SIM CARDS require special APN Settings to access the Internet. The following is an example of M2M card of Chinese operators.What is the specific APN, you can consult your mobile operator.The default APN Settings are as follows: you can see that no APN, no username, no password.3G/4G uptime means that internet keep online time ,and tx, rx data .All that showing you can access internet.Operator APN user password Dial Number China Telecom IOT card ctm2m *.m 2m or m2m ) vnet.mobi vnet.mobi *99# *99# China Unicom IOT Card unim2m.njm2mapn *99#Parameter interpretationProtocol :Do not need setup, keep default please .UMTS/GPRS/EVDO This is Dial-up Protocols,4G is same as 3G.Modem device: do not need setup, keep default please.Service Type: others do not need setup.4G Only means :work as 4G mode, no 4G signal will auto fallback to 3G.VPDN if you have VPDN card ,you can setting as that ,input APN ,Username,password.APN: Access Point Name, supplied from mobile sim card operatorPAP/CHAP username: supplied from mobile sim card operatorPAP/CHAP password: supplied from mobile sim card operatorDial number: keep default :*99#Advanced settings and firewall settings keep default please.3.8 L2TP,PPTP settingsThe SLK-E900-LTE just supported l2tp,pptp client that supported work as running L2TP,PPTP Router, can not supported Windows l2tp,PPTP.

Unit 3 OverviewIn this unit you will :Read a report about GM foodTake a test on fast readingRead a humorous story about preparing dinner through the InternetRead an interesting essay on the metaphors of foodFood Fightby Jeffrey KlugerNowadays more and more genetically engineered crops come into being and become part of our daily food. Are they safe to be consumed? Don't they have any bad effects? The public become skeptical about them, and even protest against them. The governments have been in a heated battle over the issue. What's the result of the battle? Can protesters get what they want? Please read the following article for the answers.The folks at McDonald's could not have expected an especially warm reception in France, but the manure in the parking lots still must have taken them by surprise. For the past three weeks it's been hard to visit a McDonald's anywhere in France without running the risk of encountering mountains of fresh manure －as well as not-so-fresh fruits and vegetables －dumped in front of the restaurantsby protesting farmers.There's a lot about McDonald's that angers the farmers －its sameness, its blandness, the culinary hegemony it represents －yet at the outset the demonstrations were remarkably genteel, with protesters occupying restaurants and offering customers an alternative meal of baguettes stuffed with cheese or foie gras. But lately things have turned nasty. Protesters are finding ever more to dislike about the uniquely American food －especially the very genes that make the McDonald's beef or bun or potato what it is.Around the world people are taking a closer look at the genetic make-up of what they're eating －and growing uneasy with what they see. In all, more than 4 500 GM plants have been tested, and at least 40 －including 13 varieties of corn, 11 varieties of tomatoes and four varieties of soybeans －have cleared government reviews.For biotech companies such as Monsanto, based in the U.S., and Novartis AG, based in Switzerland, the rise of GM technology has meant boom times.To date, there's nothing to suggest that re-engineered plants have ever done anyone any harm. Nonetheless, the European Union has blocked the importation of some GM crops, and since 1997 has required that foods that contain engineered DNA must be labeled as such. Plenty of trade watchers in Washington see the European actions as one more tweak from an increasingly powerful E. U. no longer intimidated by U.S. economic might. Even without legal action, public opinion is turning a more skeptical eye on GM technology. “There's nothingmore personal than food. "If the outcry in France indeed portends global trouble, it's by no means clear whether it ought to. For all the controversy that GM technology is causing, the fact is that biotech companies have succeeded in dreaming up some extraordinary plants. －thanks to a gene that company scientists tweezed out of the common petunia and knitted into their food plants. Other GM crops have been designed to include a few scraps of DNA from a common bacterium, rendering the plants toxic to leaf-chewing insects but not to humans.Last year in the U.S., 35% of the soy crop and 42% of the cotton crop were grown with GM seeds. Says Karen Marshall, a Monsanto spokeswoman: “These really do work and have tremendous benefits to growers.”But what happens when they don't work? Several years ago, a company developed a soybean with some genetic threads borrowed from the Brazil nut in an attempt to boost the bean's amino-acid content. The soy began acting like the nut －so much so that it churned out not just amino acids but also chemicals that can trigger allergies in nut-sensitive consumers. The company quickly scrapped the product. Last May a study published by Cornell University showed that pollen from some strains of corn with built-in pesticides can kill the larva of the Monarch butterfly, a pest by nobody's sta ndards. “When butterflies start dying,” says Kucinich, “I think it's fair to start asking questions.”Overseas, they have been asking them for some time. In recent years Europeans have become increasingly jumpy about bad food －and with goodreason. Since the outbreak of mad-cow disease in 1996, the appearance of dioxin-contaminated Belgian chickens last May and the later recall of contaminated cans of Coca-Cola in France and the Benelux nations, health officials have grown fussier about what their citizens consume.Since 1990 the E. U. has approved the sale of 18 GM products. (The U.S. Government views GM components in foods as mere additives and thus does not require the Food and Drug Administration to approve them. ) This year the E. U. banned the importation of non-approved GM corn. In the U.S., GM strains are mixed with ordinary strains, so the country's entire corn export to Europe was effectively outlawed. “Until we have new rules, we don't want new substances released,” says Jürgen Trittin, Germany's Environment Minister. “It's a de facto moratorium.”But one country's moratorium is another country's protectionism, and the U.S. is suspicious of Europe's action. Tension between the U.S. and the E. U. was already running high recently after Europe decided to continue a ban on hormone-raised U.S. beef and the U.S. hit back with a 100% tariff on some E. U. food exports. Coming in the midst of such a catfight, the GM ban looks like vengeance as much as prudence. What's more, if Europe is so worried about GM products, why is it growing them? France produces its own small crop of GM corn and uses more of the stuff than any other country in Europe.The transatlantic food fight will probably be high on the agenda of the World Trade Organization when it meets in November －good news forcompanies like Monsanto. While the move made Monsanto a Wall Street darling for a while, investors aren't as sweet on it anymore. A year ago, Monsanto stock perched at a lofty 63; today it's mired in the upper 30s.Events in Washington could make things worse. Since lawmakers have not yet addressed the labeling question, private groups are hoping to take the lead. Environmental organizations, along with Jewish and Muslim groups, have waded in, lobbying the FDA for labeling and in some cases filing suits to compel it. Their legal claim is bolstered by internal FDA memos in which the agency's own scientists expressed doubts about GM products. A scientist noted the “profound difference” between genetically engine ered crops though he stressed that different needn't mean dangerous.Still , it's becoming clear in Washington that the labeling problem is not going away. U.S. Agriculture Secretary Dan Glickman admits that ultimately the activists will probably prevail. Glickman hopes that labels will not be written to alarm consumers but instead to inform them, letting them know that while a product was manufactured with the aid of genetic techniques, it can also, say, lower cholesterol.In a demand-driven market, however, they would ignore it at their peril. In Europe the Gerber baby-food company, a division of Novartis, gave in to anti-GM sentiments and announced that its products would no longer contain genetically modified ingredients. “This decision was not a safety issue,” insists Novartis spokesman Mark Hill, “but rather a response to preference expressed by ourconsu mers.” Not for the last time, to be sure, it's consumers who will have the final word.(1411 words)(From Time, September, 1999 )D. Discussing the following topics.1. What is “genetically modified food”? Are you in favor of consuming GM food? Why? 答案：Genetically modified food is made from crops and vegetables genetically changed by scientists. GM food has aroused great dissentions among governments, scientists, farmers, and consumers. On one hand are the high quality crops due to the gene technique, on the other hand are the potential risks.（While giving your ideas, consider the interests of different peoples.）2.What's your comment on the last sentence of the article: “it's consumers who will have the final word”?From the text we can see that the food fight between the U.S. and the E. U. comes as much from the concern for their own interests as from safety considerations. While the E. U. banned the non-proved GM food from the U.S., France is still churning out GM crops. Anyway, it shows that people are more alert to the potential dangers of the GM food. （Your comments can be positive or negative. Consider that while the consumers' attitudes determine the popularity of the GM food, the government, scientific research, media propaganda and other factors can influence the consumers' decisions.）Text 2A Dinner @ Margaret'sby Margaret CarlsonI could hear the Champagne corks popping.There were a few difficulties. Everything had to be come from the Internet, no going to the store, and I would have to write about it. There's no such thing as a free dinner.Immediately, I e-mailed an invitation to our local Internet hero, American Online CEO Steve Case. A reply came by phone: Would we mind faxing the information?Not at all, but if Mr. You've Got Mail regresses to old tech, can e-commerce really be that easy? With Case onboard, and TIME's Person of the Year issue to dangle before guests, I pursued a Noah's Ark theory of who else to invite: two members of Congress, two teachers, two candlestick makers. I warned everyone they would be TIME's guinea pigs.With the party set for Sunday night, the plan was to give myself a week to order, , find a middle ground between ordering the totally exotic (alligator meat) and the reliably prosaic (ham),First things first: I needed a new salt shaker and a tablecloth that actually fit. I ordered both from Williams-Sonoma (williams-sonoma). This is where I first felt Screen Rage, a risk at many sites. This arises after you've just filled in every last scrap of personal data, except your shoe size and SAT scores, and the screen freezeson you. Don't think that Mr. Internet has saved anything for you. (If God is a woman, then the Web is a man, silent and indifferent, with a short attention span.) You have to start over. And over.Getting great coffee was a comparative breeze. I went directly to the sources －a Hawaiian plantation, cornwellcoffee, for Kona, and to bluemountaincoffee for Jamaica's Blue Mountain beans. This is also when I became a Coffee Bore. At most sites it's easier to get in than to get out, since Webmasters tend to fill all the space available, which online is infinite. Did you know that Kona beans thrive in the dark volcanic soil, sunny mornings and cloudy afternoons of Hawaii? I didn't either, but I've brought it up at three parties. I've turned into the kind of person I used to avoid.For real food I thought holiday season and went hunting for a goose. At goose I found I could acquire a rifle for the purpose －it's an outdoors store. As in life, you need a friend of whom you can ask anything: What is love? What's the GDP of Monaco? Where can I buy a goose? The easily distracted might choose to go elsewhere, for there are no nonstop flights at AskJeeves. The whimsical Jeeves served up Mother Goose, along with the chance to hear one (a nasal honk right out of your laptop) and a recipe (Remove stray pinfeathers. Place orange rind and celery leaves under the loosened skin. Truss). That was enough goose for me.The encyclopedic Jeeves brought me to goose liver, which led me to foie gras, which took me finally to France Gourmet Traditions (gourmet-tradition), a Parisian grocer that had precisely what I wanted. Jean-Marc Donce could get the foie grasto me on time －if I were in the Paris bureau. At its site a Strasbourg charcuterie posted this bad news: “Cannot at this time ship. USDA does not return our calls.” Funny, I have that very same problem with government agencies.A few more clicks, and I found the same pâté at Greatfood, which I ordered, along with mustards and cheese. It's a luxurious site with Hollywood-studio visuals. It was at GreatFood that I met temptation in the form of dinner for 24 at the click of a mouse. But the meat worked out to about $40 a pound and...it would have been wrong.GreatFood had a link to Omaha Steaks (omahasteak), which I'd seen advertised but never tried. There was a scrumptious picture of beef Wellington －very festive, very holiday －with a bonus gift of six 4-oz. sirloins. Maybe there is such a thing as a free dinner, after all.I went to Napa Valley at the eponymous wine (What luck to nail down that name), proved I was 21 and ordered better wine than I'd ever served. Since I was already in California anyway, I called up Patisserie Lambert (patisserielambert), where I'd eaten in real time －I mean, real life. It's a small shop, remarkably cybersophisticated, with visuals so good you could almost smell the madeleines. And there it was, the cake of my dreams, Chocolate Fantasia, three layers of chocolate caramel mousse cake. A dramatic dessert can redeem many a main-course sin, so I went for it. But Lambert quickly replied that a three-tiered cake was too dicey to ship. Then send the layers separately, I said. Some assembly required? No problem. Then came word that this was actually a wedding cake. Hey,pal, no problem. I'll have someone get married. One of these government officials will preside －captain of the ship, quick ceremony, that type of thing. Just send the cake.No go. I settled for two separate cakes with raspberry sauce on top. In a marvel of packaging, considering their delicacy, they arrived intact. Just to amortize the FedEx charges, I threw in a couple of tomato tarts. Major cost lesson: it's not the food, it's the shipping that kills you.There is no grocery website that delivers to my ZIP code, so fresh vegetables are hard to come by －thank goodness. I find the very sight of raw broccoli and cauliflower on a buffet table dispiriting. I don't go to parties looking to balance my diet with the four major food groups or to consume the recommended daily allowance of fiber. For my own evening party, I hit Cajun Joey's Specialty Foods (cajun-joeys), where sugar is the fifth major food group. Joey hasn't met a vegetable that can't be mashed, pureed, or creamed. The carrots, corn, spinach and artichokes looked great and ended up tasting like candy. I was thrilled.I can't tell exactly just when the task of looking for food on the Web finally began to overwhelm me. It might have been when I found out that because of the law in Washington, the wine would take at least ten days for delivery. But wait...fast delivery was possible to West Virginia. The political columnist in me wanted to know why: the power of Senator Robert Byrd? Some anomaly in the jurisdiction of the Bureau of Alcohol, Tobacco and Firearms? But the Martha Stewart in me just wanted the wine. A round trip to West Virginia would take more time than I had left,yet I needed a case of Merlot to ensure that my guests were less than keenly sensitive to the cellophane and cardboard from which their meal had so recently been liberated. I needed a way around the Rules. What if I could find a local store with a website but faxed the order? My seven years covering the Clintons were coming in handy. How do I get a case of wine to my doorstep by Saturday? Don't ask, don't tell.The trouble didn't necessarily end with delivery. When I sampled the beef Wellington, although remarkably juicy and delicious, I realized it wasn't going to slice cleanly into pieces suitable for lap dining (). I was worried enough to e-mail my editors in New York City: How about a back-up ham, that mainstay of Irish funerals? “Boring,” they replied.But not as boring as going hungry. Dinner by committee was my worst idea yet. Through Jeeves, I reached the Smithfield Collection (smithfield-companies/collection), and despite the pretentious name for a company that slaughters pigs, I got delivery of a crusty, honey-soaked ham in an ice chest left under the porch, per my instructions, in one day's time.At this point, I realized I needed a real-life Jeeves. Who better to serve food with pride sufficient to obscure its Internet origin? Ironically, my virtual Jeeves couldn't produce a human one. I located a domestic agency in Beverly Hills on my own, but its best price for a footman in a morning coat was $500, minimum. In a panic, I had our bureau administrator, Judith Stoler, call the caterer she uses for TIME functions, which, by the way, has an online site. A waiter would come onSunday night. Was this breaking the rules? Let's just say there's no controlling legal authority.There are many outlets for flowers, but it is hard to get just what you want －pale peach, but please, no pink －if your screen, like mine, bleaches the colors. The good news is that the roses I ordered arrived fresh and on time. The bad news is their color roughly matched that of the ham.On Saturday, calling frantically for items that hadn't arrived, Not to single out Williams-Sonoma －because it happens just about everywhere －but when you get your stuff depends on what a company's definition of “submit now” is. You submit, they process, and depending on the distributor, or the manufacturer, the popularity of your item, or who's out with the flu that day, you will get it overnight －or in a week. The polite “associate” at Williams-Sonoma sent me an apron and refunded my shipping costs. I guess there's such a thing as a free apron.Since the tablecloth would come too late for the party, I sponge-ironed the creases out of my old one until it almost fit. The foie gras, sourdough and olive Pugliese breads from San Francisco did not arrive until Tuesday. I became a culinary Luddite, baking two dozen rolls. On the day of the dinner, the waiter called in sick at 4 p.m. Well , that's why God made daughters －and editors visiting from Manhattan who know their way around a corkscrew.Dinner and a good time were had by all, confirming my belief that people go to restaurants for good food and to friends' houses for good company. There were lots of leftovers. And the ham was the size of an aircraft carrier. The morning after, Istaggered to my desk and clicked my way to D.C. Central Kitchen (), which recycles food to homeless shelters. A team came right away and wiped out all traces of My Cyberdinner.My effort cost more than $2 000. That's not exactly a value meal. But when I read that during the week I was dining à la Web, Internet users spent more than double what had been spent the preceding week, I felt pleased that in this little piece of Web history I had played a part. Next time I have people over, I'm likely to revert to my old ways. I could have crawled to Safeway and back in the time it took to make an Internet dinner. But it was nice meeting Jeeves, even though he didn't work out in the end.All in all, a virtual success.(2 010 words)B. Discussing the following topics.1. Please illustrate briefly how Margaret arranged her feast. If you have had the experience of shopping through the Internet, please give an account of it. 答案Since Margaret had to get all she needed though the Internet, she first ordered a new salt shaker and a tablecloth through william-sonoma, and got coffee and beans respectively at cornwellcoffee and bluemountaincoffee. After a lot of troubles, she finally got goose liver at Greatfood for real food. She then got a cake at patisserielambert in California. To solve the problem of fresh vegetables she hit cajun-joeys. And she got ham through smithfield-companies/ collection. She also ordered flowers through the Internet. She got wine, and a servant from the localstores which had a website, since she could not get them through the Internet on time or at a reasonable price. It turned out that some of her orders did not arrive on time and the dinner cost much more that it was worth. That's why Margaret called ita virtual success.2. What's your viewpoint about e-commerce?答案E-commerce is aimed to meet the customers' demands with greater efficiency. Despite its present defects, it is commonly believed to have a bright future. (Develop your own idea.)Text 1Food FightAbout the AuthorJeffrey Kluger is a senior writer at Time magazine, covering science in general and the space program in particular.

The Wireless Motherboard Hardware PlatformThe wireless motherboard platform is a demo, evaluation, and development platform for EZRadioPRO radio ICs. It consists of a wireless motherboard and interchangeable MCU and RF pico boards.Figure 2.8-Bit Wireless Motherboard PlatformEZRadio-DK User ’s Guide5.1. The Wireless MotherboardFigure 3.Wireless MotherboardThe wireless motherboard contains four pushbuttons, four LEDs, and a buzzer, which function as simple user interfaces. A graphical LCD displays menu items for range testing purposes, and a potentiometer demonstrates the analog capabilities of the MCU. A switch supports the power options of the MCU’s built-in dc/dc ing the current measurement jumpers, current consumption can be measured separately either for the MCU, the radio, or the peripherals. The motherboard contains test pins for all I/O pins of the MCU and for all digital pins of the radio. In addition, there are SMA connectors for the GPIOs of the radio for connection of test equipment. A USB communication interface as well as a built-in Silicon Labs USB-to-C2 debug adapter are integrated onto the board so that the wireless motherboard (WMB) can be directly connected via USB to the PC for downloading and debugging code on the MCU. There is also an interface connection for sensor modules. The MCU is also connected to the RF pico board through a connector pair.MCU Pico BoardRF Pico BoardCurrentMeasurement PinsRadio Test PinsRadio GPIO ConnectorsBuzzerReset Button Push Buttons Potentiometer MCU DC/DC Converter Switch MCU Test PinsPower Supply Switch Sensor Module Connector External Power Supply Connection USBCommunication and Debug InterfaceEZRadio-DK User’s Guide5.2. Power SchemeThe power source of the platform can be selected with the “SUPPLY SELECT” power supply selector switch on the WMB board. If this switch is in the “USB” position, supply voltage is provided by the PC that is connected to the “J16” mini USB connector. If this switch is in the “BAT” position, the supply voltage is provided by two AA batteries in the battery holder on the bottom side of the board. If the “SUPPLY SELECT” switch is in the “EXT” position,supply voltage is provided by an external power source through the “TP7” and “TP9” points.Using the “MCU dc/dc” switch, the internal dc/dc converter of the C88051F930 MCU on the MCU pico board can be activated if the connected pico board supports this function. If the switch is in the “OFF” position, the MCU’s dc/dc converter is inactive, and the supply voltage is only determined by the state of the “SUPPLY SELECT” switch.Positioning the switch to either “LDO (1.25V)” or “1 CELL” position will turn on the MCU’s dc/dc converter by connecting 1.25–1.5V supply voltage to the VBAT pin and removing external power from the VDC pin. The MCU will provide 1.9V in the default setting on its VDC pin to all the other connected loads. Since this current is limited,it may be necessary to disconnect or disable some loading part of the board. For further details, see the MCU data sheet and the board schematic. The board schematic can be found in the EZRadioPRO Development Kit User's Guide. A complete CAD design pack of the board is also available at .5.3. RF Pico BoardFigure 4.RF Pico Board Top SideThe RF pico board is a radio module that contains an EZRadio radio IC, matching network, and an SMA connector on the top side. These components (apart from the antenna connector) are covered by a metal shield for noise reduction. The digital signals of the radio (SCLK, SDI, SDO, NSEL, SCL, SDA, VDD and GND) can be accessed on test points at the edge of the board. The boards also have a factory-loaded board identification memory (EBID)on the bottom side that contains data describing the board properties. Any RF Pico board can be connected to the WMB via the unified RF Pico connector-pair on the bottom side of the board. Table 4 lists the connections between the MCU and the radio or other peripherals.Some GPIOs of the MCU has dual function. Primary functions are factory connected on the WMB. Secondary functions can be connected by desoldering a 0 resistor that connects the primary function and soldering it into the proper position to connect the secondary function. Secondary connections are listed in parenthesis in Table 4.EZRadio-DK User ’s GuideTable 4.
