**BR SX: RS485 4-wire connection:** additional devices provided with RS485 port (indicated as RS1,2,3...N) are connected in parallel. The termination of the serial port is carried out only on the last instrument of the network. The serial module is provided with a jumper for the termination of the RS485 network as shown in the figure above. **Note:** particular types of cables or plants may require an external termination. For the network connections use twisted cable type AWG26. ## **Programming UDM35 by means of PC** **==> picture [147 x 209] intentionally omitted <==** **----- Start of picture text -----**

UDM35 is programmable by PC by means of the UdmSoft software (available on request). The user can program all parameters of UDM35 that will be subsequently uploaded and set in the instrument by the RS485 network (BRSX). Should UDM35 be without the RS485 serial module, all programming parameters will be uploaded and set in the instrument by the RS232 auxiliary serial connection (1) located on the side of the measuring input module using the special connection cable (2) available on request, as shown in the figures on the left. It is also possible to program the instrument using the dot connector (1) by means of the HyperTerminal Windows functions of a PC. **Note:** the RS232 auxiliary port IS NOT insulated from the measuring inputs. **12** Specifications are subject to change without notice UDM35 DS ENG 120523 **UDM35** ## **Front anel descri tion p p** **==> picture [72 x 72] intentionally omitted <==** **==> picture [134 x 36] intentionally omitted <==** **==> picture [179 x 70] intentionally omitted <==** **----- Start of picture text -----**
