Warning!
To prevent or reduce the risk of electrical shock or re, do not expose
this unit to rain or moisture. Clearing memory often may cause damage
to the memory chip, be careful not to re initialize your unit frequency
often to avoid this risk. Only use the recommended AC/DC power
adaptor.
® DP-DMX20L™ is controlled via a standard DMX controller.
Your unit and your DMX controller require a approved DMX-512 110
Ohm Data cable for data input and data output (Figure 1). We recommend Accu-Cable DMX cables. If you
are making your own cables, be sure
to use standard 110-120 Ohm shielded
cable (This cable may be purchased at
almost all professional sound and lighting stores). Your cables should be made
with a male and female XLR connector
on either end of the cable. Also remem-
ber that DMX cable must be daisy
chained and cannot be split.
Notice: 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 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 termi-
nate the line. Using a cable terminator will decrease the possibilities of
erratic behavior.
