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 090112 **UDM35** ## **Front anel descri tion p p** **==> picture [179 x 70] intentionally omitted <==** **----- Start of picture text -----**
