XLR connector pinout
To connect Stagebar 54 fixtures to a controller with an XLR output, for example, connectors are suitable if
DMX cable is used for the data link. XLR pin numbers are normally marked on connectors. Connectors
must be wired using the standard XLR DMX pin-out:
• Pin 1: Cable shield
• Pin 2: DMX Data 1 - (cold)
• Pin 3: DMX Data 1 + (hot)
Pins 4 and 5 on 5-pin XLR connectors are available for Data 2 connections in DMX 512-A or similar
systems. They must be wired as follows:
• Pin 4: DMX Data 2 - (cold)
• Pin 5: DMX Data 2 + (hot)
To avoid ground/earth loop interference, ensure that the DMX cable shield does not come into contact with
the shell or body of XLR connectors.

Connecting the data link

To connect the data link:
1. Cut power to all devices. If the luminaire has been in use, allow it to cool for at least 10 minutes.
2. Connect a suitable cable to the DMX output socket on the DMX controller and route it to the first
luminaire on the link.
3. Connect the cable to the first fixture's DMX input socket, using an XLR to RJ-45 converter cable if
necessary.
4. Continue adding fixtures, connecting DMX output to DMX input sockets.
5. On the last fixture in each chain on the link, insert an RJ-45 DMX termination plug in the DMX output
socket.
6. When you have made all connections, set up the fixtures as described in the next section of this manual
before applying power.
