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 (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.

UDM40 is programmable by PC by means of the UdmSoft software (available on
request). The user can program all parameters of UDM40 that will be subse-
quently uploaded and set in the instrument by the RS485 network (BR SX).
Should UDM40 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 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.
