Termination reduces signal transmission prob-
lems and interference. It is always advisable to
connect a Dmx terminator, (resistance 120 Ohm
1/4 W) between pin 2 (Dmx-) and pin 3 (Dmx+)
of the last fixture.

NOTICE:
• Be sure to follow figures 2 & 3 when making your own cables. 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 behaviour.
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.
Using a cable terminator (Art. No. K3DMXT3) will decrease the possibilities of erratic behaviour.
• 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. The chart below details the correct cable conversion.
