USE AND TERMINATION OF RS 485 LINES
The control unit is equipped with 2 independent RS 485 lines (RS485_A and RS485_B) both
with adaptation of the line impedance by inserting 2 riders at 2.54 pitch.
Line adaptation is necessary when the control unit is located as a "terminal" element of BUS
485 (start or end of the route).
To adapt the RS485_A line, insert the Jumper in connectors J22 and J23
To adapt the RS485_B line, insert the Jumper in connectors J20 and J21
