You can configure the port for open-drain or push-pull output.*+5 V Output+5 V—The voltage source provided by the USB host.The voltage is nominally 5 V, but varies from system tosystem.GND—Ground—The reference for the digital signals and the+5VDC supply.NC—No Connect—Do not connect any signals to thisterminal.* If you configure the DIO port for open-drain output, you must supply pull-up resistors to V cc (3.3 or 5 V). The resistor value must not be lower than 1 kΩ.USB-8451 OEM Digital I/OThe USB-8451 OEM has eight single-ended digital lines, P0.<0..7>.Static DIOEach USB-8451 OEM DIO line can be individually programmed as a staticDI or DO line. You can use static DIO lines to monitor or control digitalsignals. All samples of static DI lines and updates of DO lines are softwaretimed.Digital Output InformationThe default configuration of the USB-8451 OEM DIO port is push-pull,allowing 3.3 V operation. You can add an external pull-up resistor (Rp) toachieve 5V operation, as shown in Figure4. Do not use a pull-up resistorof less than 1 kΩ.Figure 4.

SDA and SCL must be pulled upexternally. Refer to the I2C specification to select the correct resistor valuesfor your bus.Figure 7. I2C Interface to Two PeripheralsI/O ProtectionEach DIO, SPI, and SPI CS signal is protected against overvoltage,undervoltage, and overcurrent conditions, as well as ESD events. However,you should avoid these fault conditions by using the following guidelines:•If you configure a line as an output, do not connect it to any externalsignal source, ground signal, or power supply.•If you configure a line as an output, understand the currentrequirements of the load connected to these signals. Do not exceed thespecified current output limits of the USB-8451 OEM.•If you configure a line as an input, do not drive the line with voltagesoutside of its normal operating range.USB-8451 OEM © National Instruments Corporation 9USB-8451 OEM Specifications•Treat the USB-8451 OEM as you would treat any static sensitive device. Always properly ground yourself and the equipment when handling the USB device or connecting to it.CautionTake special care with respect to the I 2C SDA and SCL lines. To allow for externalpull-ups, the circuit protection has been removed. Do not exceed the specified voltages for these signals.Power-On StatesAt system startup and reset, the hardware sets all DIO lines tohigh-impedance inputs. The USB-8451 OEM does not drive the signal high or low.+5 V Power SourceThe USB-8451 OEM supplies a nominal 5 V from two pins, one on each screw terminal block. The voltage source is provided by the USB host. The voltage is nominally 5 V, but varies from system to system. Refer to the Specifications section for more information about USB bus power specifications. This source can be used to power external components.NoteWhile the device is in USB suspend, the output is disabled.CautionWhen using the 5 V source, understand the current requirements of the loadconnected. Do not exceed the specified current output limits of the USB Vbus.SpecificationsThe following specifications are typical at 25 °C, unless otherwise noted.Digital I/O and Chip SelectsNumber of linesP0.<0..7>.........................................8CS <0..7>.

You must have all coversand filler panels installed during operation of the device.Do not operate the device in an explosive atmosphere or where there maybe flammable gases or fumes. If you must operate the device in such anenvironment, it must be in a suitably rated enclosure.If you need to clean the device, use a dry cloth. Make sure that the deviceis completely dry and free from contaminants before returning it to service.Operate the device only at or below Pollution Degree 2. Pollution is foreignmatter in a solid, liquid, or gaseous state that can reduce dielectric strengthor surface resistivity. The following is a description of pollution degrees:•Pollution Degree 1 means no pollution or only dry, nonconductivepollution occurs. The pollution has no influence.•Pollution Degree 2 means that only nonconductive pollution occurs inmost cases. Occasionally, however, a temporary conductivity causedby condensation must be expected.•Pollution Degree 3 means that conductive pollution occurs, or dry,nonconductive pollution occurs that becomes conductive due tocondensation.You must insulate signal connections for the maximum voltage for whichthe device is rated. Do not exceed the maximum ratings for the device. Donot install wiring while the device is live with electrical signals. Do notremove or add connector blocks when power is connected to the system.Avoid contact between your body and the connector block signal when hotswapping modules. Remove power from signal lines before connectingthem to or disconnecting them from the device.© National Instruments Corporation15USB-8451 OEM SpecificationsOperate the device at or below the Measurement Category I1. Measurementcircuits are subjected to working voltages2 and transient stresses(overvoltage) from the circuit to which they are connected duringmeasurement or test. Measurement categories establish standard impulsewithstand voltage levels that commonly occur in electrical distributionsystems. The following is a description of measurement categories:•Measurement Category I is for measurements performed on circuitsnot directly connected to the electrical distribution system referred toas MAINS3 voltage. This category is for measurements of voltagesfrom specially protected secondary circuits. Such voltagemeasurements include signal levels, special equipment, limited-energyparts of equipment, circuits powered by regulated low-voltage sources,and electronics.•Measurement Category II is for measurements performed on circuitsdirectly connected to the electrical distribution system. This categoryrefers to local-level electrical distribution, such as that provided by astandard wall outlet (for example, 115 V for U.S. or 230 V for Europe).Examples of Measurement Category II are measurements performedon household appliances, portable tools, and similar E Series devices.•Measurement Category III is for measurements performed in thebuilding installation at the distribution level. This category refers tomeasurements on hard-wired equipment such as equipment in fixedinstallations, distribution boards, and circuit breakers. Other examplesare wiring, including cables, bus-bars, junction boxes, switches,socket-outlets in the fixed installation, and stationary motors withpermanent connections to fixed installations.Measurement Category IV is for measurements performed at the primaryelectrical supply installation (<1,000 V). Examples include electricitymeters and measurements on primary overcurrent protection devices andon ripple control units.1 Measurement Category as defined in electrical safety standard IEC 61010-1. Measurement Category is also referred to as Installation Category.2 Working V oltage is the highest rms value of an AC or DC voltage that can occur across any particular insulation.3 MAINS is defined as a hazardous live electrical supply system that powers equipment.
