RS232
RS232 port can be used to communicate and also to program the module.
Z-NET or EASY Z-PC are the Seneca configuration softwares.
RS232 serial communication port use the following communication parameters :
2400,8,N,1
RS232 and RS485 port use the same Modbus protocol. When RS232 communication is
established, the serial RS485 bus network will be not enable. The RS485 port will return
automatically active some seconds after the last data packed received from RS232 port.
The 3,5 mm DB9 jack stereo connector for RS232 communication can be assembled as
indicated in the following figure or purchased as an accessory (cod. PM001601).
RS485
Connection for RS485 communication with the Modbus Master
system as an alternative to Z-PC-DINx bus.
Note: the indication of RS485 connection polarity is not standard,
it may be inverted on some masters.

PARAMETERS SETTINGS
The 4 inputs parameters can be selected through the configuration softwares:
Z-NET or
EASY-Z-PC.
Every input can acquire thermocouple signal or voltage signal. The table below
show the start and full scale values for every type of thermocouple and for voltage.
NOTE:
In order to avoid measurement errors caused from external interferences we suggest
to short-circuit the unused thermocouple input channels.
