SET UP (continued)
Data Cable (DMX Cable) Requirements (For DMX and Master/Slave Operation):
The Stinger II can be
controlled via DMX-512 protocol. The Stinger II is has 2 DMX channel modes, a 2 channel mode and 9
channel mode. The DMX address is set electronically using the controls on the back
panel of the unit. 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 remember that DMX cable must be daisy chained and
cannot be split.
Notice:
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 con
nect 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
behaviour.
XLR Pin Configuration
Pin1 = Ground
Pin2 = Data Compliment (negative)
Pin3 = Data True (positive)

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 behaviour. A terminator is a 110-120 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 (ADJ part number
Z-DMX/T) will decrease the possibilities of erratic behaviour.
Termination reduces signal errors and avoids
signal transmission problems and interference.
It is always advisable to connect a DMX
terminal, (Resistance120 Ohm 1/4 W) between
PIN 2 (DMX-) and PIN 3 (DMX +) of the last
fixture.

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.
