Line-Light

Artistic Licence Line-Light
Line-Light
Basic DMX Tester

The Line-Light is a simple DMX512 and CMX tester. The product is built into a standard XLR connector and is available in both 5pin and 3pin versions.

Operation is simple, and can test for and indicate the following conditions.

No DMX present on cable

Connect Line-Light to the DMX output. If Line-Light does not illuminate, either no DMX is present on the cable or the cable is damaged.

DMX512 pins 2 & 3 miswired

Connect Line-Light to the DMX output. Set all channel levels to full at the console. Line-Light should illuminate in GREEN. Set all channel levels to off at the console. Line-Light should illuminate in RED. If the colours are reversed, then pins 2 & 3 of the cable are swapped.

Faulty DMX512 output from console

When a DMX512 cable driver fails, the signals on the cable do not change. If Line-Light illuminates in either RED or GREEN and does not flicker or change, the DMX output from the console is probably faulty.

Good DMX512

In normal operation Line-Light will flicker between RED and GREEN to produce an ORANGE colour as the information output by the console changes.

Features

Compatible with DMX512, DMX512 (1990), DMX512-A
