How It Works

The IR T2 can be controlled remotely via RS-232 commands. The commands include:

  • Powering the unit on/off
  • Remotely setting the IR frequency (2.3/2.8 or 3.3/3.8)
  • Muting the outgoing audio without powering off
  • Turning back panel LEDs on or off
  • Troubleshooting abilities

A full list of commands is available on the downloads tab in the IR T2 Programmer’s Guide.


The IR T2 can also be powered over Ethernet using the included POE KT1 remote power kit. This kit includes the WCA  133 for wiring directly to a power supply, and does not include the alternative cable WCA 132 which is for wiring to a switch.
