RS232 PORTS
The 306 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 306
configuration.

ETHERNET COMMUNICATIONS
Ethernet communications can be established at either 10 BASE-T or 100
BASE-TX. The 306 unit’s RJ45 jack is wired as a NIC (Network Interface
Card). For example, when wiring to a hub or switch use a straight-through
cable, but when connecting to another NIC use a crossover cable.
The Ethernet connector contains two LEDs. A yellow LED in the upper right,
and a bi-color green/amber LED in the upper left. The LEDs represent the
following statuses:
On the rear of each unit is a unique 12-digit MAC address and a block for
marking the unit with an IP address. Refer to the CTVue manual and Control
Techniques’ website for additional information on Ethernet communications.
