SETTING THE DIP-SWITCHES
The position of the DIP-switches defines the Modbus communication parameters of the module: Address and
Baud Rate The following table shows the Baud Rate and Address values according to the DIP-switch
setting:

Note:
When DIP switches 1 to 8 are OFF, the communication settings are taken from programming (EEPROM).
Note 2
: The R S 485 line must be terminated only at the ends of the communication line.

SETTING THE DIP-SWITCHES
The parameters of each of the 4 inputs can be set using the Z-NET and EASY-Z-PC configuration software. It is
possible to get a voltage signal or a thermocouple signal. The following table indicates the start and full scale values
for each type of thermocouple and for the voltage.
