4 Maintenance & Firmware Upgrades
4.1 Remote Control Commands
The Link XPe Transmitter (L1303) is configured using the Link Configurator software running on a PC via the RS232

This allows the configuration of the transmitter; the video input type, transmitter frequency, COFDM modulation scheme
and audio input gain settings can all be set and stored in the unit.
Please refer to the Link Research website for a copy of this Link Configurator software and the Control commands.
