Avaya Room Systems Commands Interface API document includes all available commands suitable for complete control of XT Series.

• Since v8.3, control of Avaya XT7100, XT5000 / XT4x00 / XTE240 and XT Telepresence based on XT5000 or XT7100 is possible using both TCP/IP and serial interface. XT1200 can be controlled through TCP/IP (serial control not supported for XT1000 series).
• The Avaya XT Series API Commands can be used to allow skilled integrators to build from scratch their own control application OR to complete the AMX / Crestron / Extron sample control applications to cover any additional customer needs not yet included in the samples currently provided by Avaya.
• IR simulator downloads include a capture file of the IR signals from the XT Series remote control; these are difficult to acquire using AMX or Crestron capture programs
• Serial connectivity requires a USB-to-serial RS232 adapter. USB-to-serial adapters based on FTD chipset are supported. The Aten UC-232A has been tested and qualified with XT Series in the Avaya laboratories.
