RS422/485 COMMS PORT
The G306 has one RS422/485 port. This port can be configured to act as
either RS422 or RS485.
Note: All Red Lion devices connect A to A and B to B, except for Paradigm
devices. Refer to www.redlion.net for additional information.

RS232 PORTS
The G306 has two RS232 ports. There is the PGM port and the COMMS
port. Although only one of these ports can be used for programming, both ports
can be used for communications with a PLC.
The RS232 ports can be used for either master or slave protocols with any
G306 configuration.
Examples of RS232 communications could involve another Red Lion
product or a PC. By using a cable with RJ12 ends on it, and a twist in the cable,
RS232 communications with another G3 product or the Modular Controller can
be established. Red Lion part numbers for cables with a twist in them are
