The latest additions to our coaxial switch controllers offer SNMP and a web server.

The TRC Series “N” controllers have all the features of our standard single or dual switch controllers, with added SNMP capabilities.

Users can remotely perform commands and check status via SNMP (v2c) or a built-in web server. An RJ45 jack is located in the rear of the unit for the LAN connection. Remote connections can also be made via rear mounted terminal strips.

Key switches and pushbuttons on the front of the controllers allow for local mode operation, locking out SNMP control as well as wired remote commands. SNMP and wired status will work with the local key switch on.

The front panel switch position indicators clearly show the RF signal path and load status. An auto transfer mode allows for changing transmitters automatically if the main fails. Load testing is protected via the automatic load interlock.

As with all Tunwall controllers, there is no end user programming required. The TRC Series “N” controllers are compatible with all coaxial switches, and can also be used with AM contactors.

Three single switch controllers are available: TRC-1N, TRC-1P-N and the TRC-1PA-N. The dual switch units in the series are the TRC-2N and TRC-2A-N. Data sheets for all of these units are available for download here.

Custom designs can also incorporate the SNMP feature. If you are interested in a custom design, please contact us.
