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.
