SETTINGSM o d e sThe communication modes are set by switches on the front panel.Fig. 7 – Front panel switches, module UC485 (they are all OFF in this figure)Table 1 – Settings of the communication line modesPage Papouch s.r.o.UC485Page 7L i n e t e r m i n a t i o n a n d i d l e m o d e TERM485This device connects the impedance termination of the RS485 or RS422 line on the transmitter's side. It prevents signal from reflection at the line ends. These resistors should be connected at both ends of the communication line.TERM422This device connects the impedance termination of the RS422 line on the receiver's side. It prevents signal from reflection at the line ends. These resistors should be connected at both ends of the communication line.BIAS485This device connects the resistors which define the idle mode of the RS485 or RS422 line on the transmitter's side. They determine the idle-status levels of the communication line. (More detailed information can be found in the section "Idle mode" on page 10.)A u t o m a t i c c o n t r o l s e t t i n g sWhen automatic (time) control is used for the RS485 or RS422 line, the value T of the time delay can be set, for which the driver remains switched to transmission.Fig. 8 – Time delay for which the driver remains switched to transmissionThe default value of this delay is 460 μs; it can be changed using jumpers inside of the module. First open the module case. Unscrew the two screws (opposite to each other) on the modulecase's bottom side, loosen the screws on the top lid, and tilt the top lid out.Fig. 9 – Locations of the screws securing the top lidUC485Papouch s.r.o.Page 8There are four jumpers inside.Fig. 10 – Jumpers for setting the time delay valueThe jumpers' configuration defines the time delay value T. The default value of this delay is 460 μs; it can be changed using jumpers inside of the module. The configurations and their meanings are shown in the Table below.Table 2 – Time delay value settingSW1 SW2 SW3 SW4Papouch s.r.o.UC485I n s t a l l a t i o n f o r t h e R S485/422l i n eThe following steps are used for the UC485 converter installation for communication on an RS485 line:1) Set the switches SW3 through SW8 according to Table 1 on page 6.2) Connect the RS485 wires to the D-SUB 9M connector according to Table 3. (Cf. theconnector diagram on page 5.)Table 3 – RS485 line connection3) Connect the RS232 wires to the D-SUB 9F connector according to Table 4 using anuncrossed cable.Table 4 – RS485 line connection4) If the converter is at a line endpoint, the termination resistors should to be connected bya TERM485. Switches consider connection of resistors which define the idle status.5) Connect to the power supply.1The DTR or RTS signal is only used within modes with the DTR line control. The mode settings are described on page 6 under "Modes". Page 9UC485Papouch s.r.o.Page 10Idle modeWhen communicating on the RS485 line or the RS422 multimaster line, there may be a no-transmission status (all lines are in the receiving mode). In this case, the status of the line is undefined and it is extremely sensitive to any induced voltage (interference), which is deemed incoming signals. Therefore an idle mode should be defined by connecting suitable resistors to a line. If the line is long, the best point is at the UC485 end-of-line modules or equipment.With the UC485 converter, built-in resistors can be used, connected by the BIAS485 switches; or the resistors may be connected directly to the RS485 connector (cf. Fig. 11). For long lines, the resistor values should be higher and the termination should be connected simultaneously.SGND can also be used for connection of the cable shielding contact.Fig. 11 – Connection of resistors which define the idle modeI n s t a l l a t i o n f o r t h e R S422l i n eThe following steps are used for the UC485 converter installation for communication between two devices on an RS422 line:1) Set the switches SW3 through SW8 according to Table 1 on page 6.2) Connect the RS422 leads to the D-SUB 9M connector according to Table 5 (a drawing ofthe connectors is on page 5).Table 5 – RS422 line connection3) Connect the RS232 leads to the D-SUB 9F connector according to Table 6 using anuncrossed cable.Table 6 – RS232 line connection4) If the converter is at a line endpoint, the termination resistors are to be connected by theTERM422. For the multimaster mode, consider connection of resistors which define the idle status.5) Connect to the power supply.5The DTR or RTS signal is only used within modes with the DTR line control. The mode settings are described on page 6 under "Modes".R S232l i n e e x t e n s i o nBy using two UC485, you can extend an RS232 line to a distance of up to 1,200 m.61) Connect the RS232 line and the power supply to the UC485 converters on both ends.2) Both converters should be set to the RS422 mode according to the above-mentionedinstructions.3) Connect the cable between the converters according to Table 7 (a drawing of theconnectors is on page 5).Table 7 – RS232 extension line connection6 An RS232 line can also be extended with the aid of a special LD232 set.RS485 AND RS422 LINESAn RS485 line consists of a pair of wires, denoted by symbols RxTx+ and RxTx-7, preferably by a twisted pair. In the idle mode, the RxTx+ wire's potential is more positive than that of RxTx-. The topology is a stem line with short branches. Impedance termination devices should be connected at both ends of the stem line. The RS485 line is a half-duplex bus: data is sent and received on the same wires. Therefore the communication direction must be switched between transmission and receipt.Fig. 12 – An example of a system with an RS485 line interconnection. Termination is connected inModules 1 and 5.The DTR signal of the RS232 line can be used for the direction control, or automatic (time) control can be used.Fig. 13 – An example of a system with an RS422 line interconnection. Termination is connected inboth modules.7 Notation A (for RxTx+) and B (for RxTx–) is sometimes used.Fig. 14 – An example of a system with an RS422 line interconnection in the multimaster mode.An RS422 line consists of two symmetric pairs of conductors. It is duplex line and directly substitutes the RxD and TxD signals of the RS232 lines; one pair is used for data receipt, the other pair for transmission. The transmission conductors are denoted by symbols Tx+ and Tx-; the receipt pair are denoted Rx+ and Rx-. In the idle mode, the + wire’s potential is more positive than the – wire. Impedance terminations are connected to the line endpoints. An RS422 line can have branches; in this case, transmitters must be disconnected –mode Multimaster must be set according Table 1.POSSIBLE PROBLEMS DURING INSTALLATIONRecognising RxTx+ and RxTx- conductors:In the idle mode of an RS485 (RS422) line, the RxTx+ conductor's potential is more positive than that of RxTx-. Before measuring, we must ensure that the equipment at the other endpoint is a transmitter and either idle or sending data with a very low frequency of occurrence. If the polarity of the RxTx+ and RxTx- conductors is correct, the yellow RxD indicator must be on when data is transmitted (test it when the control signal is off and the "positive control signal during transmission" option is set).Even thought the power supply is switched on, the green indicator is off: Make sure that power supply is on, the power supply voltage is accordant with converter installing option and polarity is not reversed.The RxD remains on even if no data is being transmitted:There may be several causes of this defect:–The RxTx+ and RxTx- conductors of the RS485 line may be mutually interchanged.–An impedance termination on the receiver side is connected, but there are no resistors which would define the line's idle mode.The impedance termination is connected to the module. On the opposite side, resistors –are connected which define the line's idle mode. However, the line or one of its wires is broken.Data transmission in industry, line and protocol conversions, RS232/485/422/USB/Ethernet/GPRS/ WiFi, measurement modules, intelligenttemperature sensors, I/O modules, and custom-made electronic applications.Address:Strasnicka 3164110 00 Prague 10Czech RepublicTel:+420 267 314 267Fax:+420 267 314 269Internet:E-mail:****************。
