Usage
Each driver can be embedded in the fixture or mounted directly to it. The driver is powered and physically connected
by the Transcend POE Gateway with a rugged and reliable Transcend harness cable using a Molex Micro-Fit 4-pin
connection. If the power requirement for a group of devices is below 50W, a single Transcend PoE Gateway can power
and control multiple drivers in a daisy-chain configuration, with the easy-to-use input and output connector scheme.
