G-L-T B-4 User Instruction

Product Descriptions

This is a 4-way DMX booster with a 3-pin and 5-pin XLR input jack. This unit takes the incoming DMX
signal and splits the signal into four separate output channels. Each output channel and the input channel
are completely electronically isolated from each other, all four output channels have independent output
drivers to boost the DMX signal. In addition, a Link out/Terminate selector is used for secure linking when
you intend to terminate DMX signal.

Set-up

Power Supply Setup:

Before plugging your unit in, be sure the source voltage in your area matches the required voltage for your
B-4 Booster power supply. The B-4 Booster is only available in a 230v version. Due to variations in line
voltage from venue to venue, be sure to plug your power supply into a wall outlet with matching power before
attempting to operate.

DMX Setup:

Data Cable (DMX Cable) Requirements:
The B-4 Booster can be controlled via DMX-512 protocol and your DMX controller requires a standard 3-pin
XLR connector for data input and data output(Figure1). Connect the B-4 Booster and your fixtures together
using standard 3 pin DMX cables. The B-4 Booster uses DMX-512 protocol to operate your fixtures.
