* To test the data link with an ohm meter, disconnect the link from the controller
and measure the resistance across pins 2 and 3 of the XLR male plug. The reading
should be around 120 ohms. Readings from 400 - 20,000 ohms indicate the data
link is not terminated. Infinite resistance indicates a bad connection, broken wire, or
a defective fixture. Very low readings indicate a short circuit in the link or a
defective fixture.
