After a Monday filled with part of the network at work being down I dug up the 'luxlite' text sign that clutters one of the desks at work. Digging up the protocol it listens to was harder as all searches with luxlite talk about a different protocol (which we do use in another text sign). So, this particular 'luxlite' uses a protocol which is known as Prolite Protocol which is not too hard to program. At this moment it signals everything works.
