Single ended cable test
The SINGLE ENDED TEST display shows the short circuit status of pins 2 and 3 of the
DMX512 output connector. The display will show the following when there is a connection
between pins 2 & 3.
This test can be used to test for short circuit in the cable or to confirm that the cable is
properly terminated.
Network test
The NETWORK TEST provides a more sophisticated test for installed DMX512 networks.
This test is capable of confirming that both data distribution amplifiers and cables are
working correctly.
The test makes use of a new feature of DMX512-A, the Test Packet. This is a specific
DMX512 packet, with an alternate start code, that is designed to exercise the DMX512
network in a worst-case scenario.
The worst-case data is generated by ensuring that every bit position includes a transition.
Whilst this menu is active, ‘The Wife’ DMX Tester transmits the test data and searches for
received test data.
The ‘The Wife’ DMX Tester output is then connected in place of the lighting console. Each
DMX512 outlet can then be tested for good data. If the lighting console has the ability to
transmit test data, this can be used instead of the ‘The Wife’ DMX Tester output.
The display gives a simple Good / Bad indication.
