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 90-120 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.

1. Drain Switch -
Selects the mode in which the water is
drained out of the unit, either automatic or manual. See
page 12 for details.
2. XLR Input Jack
-
This jack is used to accept an incoming
DMX signal.
3. XLR Output Jack -
This jack is used to transmit the incom-
ing DMX signal to another DMX fixture, or transmit a Master/
Slave signal to the next unit in the chain. For best results in
DMX or Master/Slave mode terminate this jack if it is the last
unit in the chain.

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 stan-
dard 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.
