WARNING
Use the RS232 serial port only after disconnecting the high voltage input.
This communication port can only be used to program the module. Z-NET or Easy Setup are our
configuration software. The RS 232 serial port uses the following communication parameters:
2400,8,N,1.
During the use of the RS232 port, the bus will be inactive; it will reactivate automatically a few seconds
after the last message exchanged on the COM port. The DB9 connection cable 3.5 mm stereo jack can
be assembled as shown in the figure below or purchased as an accessory (code PM001601).
