3.5.1.3 Serial-2 (J22) And Serial-4 (J12) Connector
On a PIP with no Serial Port Modules (SERIF modules, which are optional), the connectors J12 and J22 are
only dummy connectors with no function.
If the PIP is equipped with SERIF-1 (RS232) or SERIF-2 (RS485) modules on the Serial-2 and Serial-4 port, the
RS232 or RS485 signals will be available on connector J12 and J22.
