Connection to privacy signs
Run a separate cable from the controller mounting location to each lighting location. Do not daisy chain
signs as this may cause the lights to be of different brightness. Two 50 ft. (15.2m) plenum rated cables are
provided with the kit.
Note that the small switch on the side of the controller must be set to the "up" position (closer to the
top of the case) for the lights to work. The "down" setting enables the external USB jack, used for
firmware updates or for the optional Bluetooth dongle supplied with the Qt100 iPad app.
