10 / 12 page 10 Specifications are subject to change without notice USCDS0407063 USC Programming USC by means of PC 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 connec- tion (1) located on the side of the measuring input module using the special con- nection 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. Note: the RS232 auxiliary port IS NOT insulated from the measuring inputs. Ordering code of the cable (2): UCOM1 1 2 To PC To USC BO R4: dual relay output +dual open collector output: the load resistances (Rc) must be designed so that the close contact current is lower than 100mA; the VDC voltage must be lower than or equal to 30VDC. VDC: power supply output Vo+: positive output (open collector transistor). GND: ground collector (open collector transistor). 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. RS1,2,3...N NON terminalized network. Terminalized network Wiring diagrams of optional modules (cont.) Vdc 3 2 1 SY TX RX GND LED 1 5 6 9 5 2 3 BO SY: RS232 direct connection to PC by means of COM port. RS232 has no termi- nalization. |
