There are some differences in DMX connectors where some some fixtures comes with a 5 pin connector or some has a crossed polarity in the connector. (+ and – are swapped.) This has, among others, been a issue with some older Martin Fixtures. text/html 2019-07-18T06:13:09+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.freestylersupport.com/wiki/dmx_basics:dmx_addresses?rev=1563430389&do=diff DMX Addresses. DMX512 is basically a system where up to 512 addresses / channels are send one by one. Only address 1 to 511 are valid for fixture because address 0 is used as sync or start frame. Each address contains 8 bit which gives the possibility of sending a value from 0 – 255 on each address / channel. text/html 2013-03-11T03:45:42+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.freestylersupport.com/wiki/dmx_basics:dmx_fault_finding?rev=1362973542&do=diff DMX Fault finding This is a small guide of how to find the most common errors when a setup doesn’t behave. First of all is to be systematic in the fault finding even in the panic phase. Nothing happens at all.

The setup consist of a PC or Console as controller and some light fixture that are to be controlled. The Controller sends some digital values using a standard named DMX512 and the fixtures then receives these values. text/html 2013-03-11T03:45:42+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.freestylersupport.com/wiki/dmx_basics:dmx_measurements?rev=1362973542&do=diff Measurement on the DMX cable.

Traditionally DMX comms cables are terminated at each end with a 5 pin xlr plug (male one end and female at the other). Only 3 of these pins are acually used and as a result many lighting fixtures now have only 3 pin xlr connections although some do have both types. text/html 2013-03-11T03:45:43+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.freestylersupport.com/wiki/dmx_basics:ltp_and_htp?rev=1362973543&do=diff LTP and HTP Introduction LTP and HTP When a stage lighting desk / Software controls channels for intensity, position, colour etc. it treats them in one of two ways – HTP and LTP.
