Serial to DMX Converters?

Hi Walts_Worker,

This may help:

Connectors

DMX512 1990 states; " Where connectors are used, the data link shall utilize 5-pin "XLR" style microphone connectors." DMX512-A(E1.11) prohibits use of any connector other than a 5-pin XLR unless there is not physical space on the device for that connector, in which case an adapter must be supplied. Unfortunately non-compliant connectors and pin-outs have been used by several manufacturers. The most common non-compliant connecter is the 3 pin XLR. One of the most inappropriate connectors is the TRS phone plug.

Color scrollers and units that are powered by a data / power cable are an accepted alternate and are often fitted with 4 pin connectors.

The pin out for the 5-pin connectors is:

1. Data Link Common
2. Data 1- (Primary Data Link)
3. Data 1+ (Primary Data Link)
4. Data 2- (Optional Secondary Data Link)

5. Data 2+ (Optional Secondary Data Link)

Here's an interface with a USB connection:

I notice that this is a 3-pin connector. What is the pin-count of your DMX interface?

Maybe some of this will help.
