Features

• Save You Money: The Pknight CA8402GA features optoisolated RJ45 DMX ports， which allows you to use cheaper Ethernet （Category 5） cables instead of expensive XLR cables, saving you money and making it perfect for fixed installations.
• Terminal Switch: Equipped with the 120ohm Terminal switch, our RJ45 DMX512 splitter can reduce the effects of signal reflections in the transmission line to ensure that a safe and reliable connection is made and maintains proper impedance for the signal
• Flexible Mounting： there are flexible mounting options to cover any situation, Not only you can place the device directly on the table, but you can also use 2 light hooks to mount it on a truss rack or install it on a standard 19‘’ rack with a few screws.
• Being Opto-Isolation: Optically isolated DMX ports provide a physical barrier between the transmitting and receiving equipment. This ensures that signals are transmitted and received cleanly, without interference. It also prevents voltage spikes and other electrical noise from damaging the connected expensive equipment.
• Standard Pinout: this unit designed initially strictly follows the ESTA Standard DMX over CAT5 pinout, so it can be compatible with most RJ45 to XLR adapters on the market.

How to transmit DMX512 over RJ45？

ESTA Control Protocols Working Group found that Category 5 or higher UTP cable, or the slightly more expensive STP cable, was as suitable for the transmission of DMX–512 data as the recommended EIA–485 data cables.

Incorporating cables for DMX data into the Ethernet cable plant of installations can provide for the use of existing DMX protocols while allowing for the future use of Ethernet protocols.

Keep in mind, this refers to DMX512A data being transported over Category 5 or 6 wiring with RJ45 termination. Though the wire is physically the same as Ethernet, the electrical properties are very different and can damage Ethernet equipment such as network switches and Ethernet adapters in computers

The datasheet below details the wiring scheme for cables linking 5-Pin or 3-pin XLR DMX connectors to standard RJ45 Ethernet connectors:

If you want to avoid wiring, it is recommended that you can buy the adapter, but before buying, please make sure that the RJ45 to XLR adapter you bought meets the ESTA standards.
