RS1,2,3...N
NON terminalized network. Terminalized network 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 USC by means of PC
To USC
1 USC is programmable by PC by means of the UscSoft software (available on request). The user can program all parameters of USC that will be subsequently uploaded and set in the instrument by the RS485 network (BR SX). Should USC 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 connector (1) by means of the HyperTerminal Windows functions of a PC. 2 Note: the RS232 auxiliary port IS NOT insulated from the measuring inputs. Ordering code of the cable (2): UCOM1
