CABLE TERMINATION

When total run of Control cable is 90" or over it is necessary to terminate
the Cable. This can be accomplished as follows.
1: Many Fixtures have some type of built in termination either auto
matic or by some type of function switch,select this in the last fixture in
the link.
2: Make or buy a Termination Plug and insert it into the last Fixture in the
link.
To make a termination plug use a Male XLR plug and solder a 90 to 120
ohm 1/4 watt resistor between pins 2 & 3 of the plug.
