1 Male 5 Pin XLR.
1 110 ohm 0.5W resistor.

To make the line terminator solder the resistor across pins 2 and 3 of the
XLR. You may like to back fill the XLR with potting compound or epoxy resin
to provide protection.


3.3 A simple DMX tester.
------------------------

This tester can be used instead of a line terminator to provide a simple
means of checking for cable continuity.

Parts required :

1 Male 5 Pin XLR
2 270 ohm 1/2 watt resistor.
1 Bi-Color LED.

The Bi-Color led has 2 LED's (one Red and one Green) back to back in the
same package. Build this into the back of a 5 pin XLR with the LED showing
out of the back. To use insert into the socket that you want to test,
Set all chanels to 0% (Preheat also = 0) The led should glow one color.
Run all chanels up to Full power (You may need to turn the dimmers off!)
The LED should glow the other color. If the led fails to light in any one of
the 2 above states then there is a short between one of the lines and pin 1.

Its limited but suprisingly useful!
