B-4 Booster
4 WAY DMX-BOOSTER
Users 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.

General Functions
Front Panel View
- Power Switch: This switch turns on and off the main power.
- Link Out / Terminate selector: This switch is primarily used for troubleshooting. When the switch is in the “Terminate” position, DMX output(4) is turned off and you can not link any more units. When the switch in the “Link Out” position, this unit allows you link a second unit.
- DMX Input: These jacks are used to receive an incoming DMX signal.
- DMX Output: These jacks are used for linkup only.
- DMX Output/ W Driver: The four DMX output channels are completely electronically isolated and each features an independent driver that boost the DMX signal.
- Fuse: F0.5A 250V 5x20mm
- Power Input: AC 230V~50/60Hz, 0.5A
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.
If you are constructing your own data cables, be sure to use standard two
conductor shielded cable (This cable may be purchased at almost all
professional sound and lighting stores). Your cables should be made with a
3-pin male and female XLR connector on either end of the cable. Also remember
that DMX lines must be daisy chained and can’t be split.
*Note:
Be sure to follow figures two and three when making your own cables. Do not
use the ground lug on the XLR connector. Do not connect the cable’s shield
conductor to the ground lug or allow the shield conductor to come in contact
with the XLR’s outer casing. Grounding the shield could cause a short circuit
and erratic behavior.
*Special Note:
Line Termination. When longer runs of cable are used, you may need to use a
terminator on the last unit to avoid erratic behavior. A terminator is a 120
ohm 1/4 watt resistor which is connected between pins 2 and 3 of a male XLR
connector (DATA + and DATA -). This unit is inserted in the female XLR
connector of the last unit in your daisy chain to terminate the line. Using a
cable terminator will decrease the possibilities of erratic behavior.
Termination reduces signal errors and avoids signal transmission problems and
interference. It is always advisable to connect a DMX terminal, (Resistance
120 Ohm 1/4 W) between PIN 2 (DMX-) and PIN 3 (DMX +) of the last fixture.

DMX Signal Cable. 120 ohm impedance DMX signal cable MUST be used for signal
connection.
5-Pin XLR DMX Connectors.
Some manufactures use 5-pin XLR connectors for DATA transmission in place of
3-pin. 5-pin XLR fixtures may be implemented in a 3-pin XLR DMX line. When
inserting standard 5-pin XLR connectors in to a 3-pin line a cable adaptor
must be used, these adaptors are readily available at most electric stores.
The chart below details a proper cable conversion.

Conductor| 3-Pin XLR Female(Out)| 5-pin XLR Male(In)
Ground/Shield| Pin 1| Pin 1
Data Compliment(-signal)| Pin 2| Pin 2
Data True(+signal)| Pin 3| Pin 3
Not Used| | Pin 4 – Do Not Used
Not Used| | Pin 5 – Do Not Used
WARNING!!!
