11.3 pLAN web wiring - “multi-KITA”
If the air conditioning system has more units which interact with
each other in a pLAN logical “master-slave”, you need to connect
the machines via the bipolar cable screened according to the
following scheme:
Scheda 1
(master)
Tx+
Tx+
Tx+
Tx+
tx-
tx-

GND

Scheda 2
Scheda 3
Scheda 4
The wiring should be done in the port dedicated to the “P-2 LAN”
tab (see point 11 on the scheme in chapter 12).
