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.
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).

UDM60 is programmable by PC by means of the UdmSoft software (available on
request). The user can program all parameters of UDM60 that will be subse-
quently uploaded and set in the instrument by the RS485 network (BR SX mod-
ule) or by the RS232 connection (BR SY module). Should UDM60 be equipped
without the RS485 or RS232 serial module, all programming parameters will be
uploaded and set in the instrument by UdmSoft and the RS232 auxiliary serial
connection (1) located on the side of the measuring input module using the spe-
cial 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.
