Backlight controller
When the ILS22 is delivered in a standard setup, an internal PC is used to control the system and the backlight and
relays controller. The internal PC has 4 serial comm ports, of which COM4 is used to communicate with the backlight
controller (see above scheme). In situations where an external PC is used, ILStranslator needs to know to which serial port
will be used to address the backlight controller inside the ILS22.
Note that only the serial port can be changed. The other communication parameters are fixed.
