SiYear DMX adapter cable, 30 cm

If your DMX lighting setup uses a five-pin XLR connection but you want to run the signal over CAT-5, this short adapter is designed to bridge those connector types. It suits a different need than a ready-made DMX cable: it lets you use ordinary CAT-5 cable for the run.

The cable has a five-pin XLR female connector on one end and an RJ45 female connector on the other. Its listed length is 30 cm/12 inches.

If you prioritize reusing CAT-5 cable, this format is worth considering, if you prefer a single, purpose-built cable with no separate adapter, a complete DMX cable may be simpler.

Where it shines

The practical use is in a lighting setup where a controller and LED equipment use DMX512, but the connection needs to transition between five-pin XLR and RJ45. Pair the adapter with ordinary CAT-5 Ethernet cable to create a DMX512 cable run, as described for LED controllers, the DMX-CON controller series, and LED RGB strips.

For example, you could connect the adapter at a five-pin XLR DMX output, then use a CAT-5 cable to reach compatible lighting equipment. That can be useful when CAT-5 is already part of your setup or is the cable format you want to use. It’s a great fit if your gear calls for the stated connector types and DMX use.

The adapter itself is short, so it works as a connector bridge rather than as a long cable run. The CAT-5 cable is separate, this listing describes the adapter, not a complete-length Ethernet or DMX cable.

Key points

The female-to-female layout matters: both the five-pin XLR and RJ45 ends are female. Check the connectors on your equipment and cable before choosing it, since this adapter is not a replacement for a different gender or pin count. Its stated purpose is to adapt the connector format for DMX use, not to make incompatible lighting equipment compatible.

The jacket is flexible PVC, with nickel-plated connectors and rubber strain relief. Those details speak to construction and contact design, but the listing does not provide performance testing or a supported cable length. It may not suit you if your setup needs a different XLR pin count, another connector gender, or a longer lead without adding a separate cable.

Best use cases

This adapter makes the most sense when you already have, or specifically want to use, CAT-5 cable for a DMX512 lighting connection with five-pin XLR equipment. It can also help keep a setup modular: use the short adapter at the connection point and choose the separate cable length to suit the layout.

For a straightforward installation, confirm the device connection is five-pin XLR, the other side needs RJ45, and the intended signal is DMX512. The product description names LED controllers and RGB-strip controller applications, but does not give a detailed compatibility list or wiring diagram. If your equipment documentation specifies a particular pinout or cable requirement, use that information before connecting it.

Is it worth it?

The appeal here is specific rather than universal: a compact XLR-to-RJ45 adapter can be handy when CAT-5 is the preferred cable format for a compatible DMX lighting setup. Its short 30 cm/12-inch length keeps the adapter itself manageable, while the separate cable provides the rest of the reach.

Choose it when the connector arrangement matches your equipment and you want to build the run around CAT-5. Skip it if you need a complete cable, a different connector configuration, or clear documentation of a particular pinout before purchase. Those requirements are not detailed in the available product information, so this is best treated as a connector adapter—not a fix for every DMX connection mismatch.
