DMX512 RDM

DMX512-RDM


Many customers are confused the DMX512 and DMX512 RDM.  

"What’s the difference between the DMX512 and DMX512-RDM" .

This is the most requently asked from customers who are insterested in.


As all guys known, the DMX512 signal is transferred from DMX console (device) to led pixels.


Today let’s share our experiences on the DMX512 RDM with simple worlds.

RDM, is an acronym for Remote Device Management, it is an advanced protocol used in DMX512 lighting control.


Through the RDM protocol to do the communication between the console(device)  and individual lights.

Noticed the “communication” that means is bidirectional transmission between the devices (controllers) and pixels.


That means we can remotely check the work status for each channels’s of pixels products like port of deive, channels. voltage, current, working time ,power ,temperature and trouble reporting from individual lights or devices.

You can check the picture below for our RDM testing. Below RDM picture is DMX512-RDM IC to control RGBW leds. 


From the picture, you can monitor individually pixels status and troubleshoot easily that you don’t need to clear the problems one by one like before.


In a short word, the RDM most notable feature is the data feedback function, you can see each pixel products’s work status in the software when individually pixels working.


So we can say, DMX512 –RDM is the RDM over DMX512 protocol.


I think some guys will ask, does the RDM has extral signal ? The answer is NO.

RDM shares same signal with DMX512.


Of course, RDM working, except the software in PC, we should do not forget the controller too.

Due to most LED pixels products support Artnet, but no RDM protocol, so you need to confirm your controller if can support RDM protocol. 

But if you do not have, you can contact us that we can offer you the RDM controllers


The RDM controllers can then be used to discover RDM devices connected to the DMX outputs of those pixel products.


So, Normally the DMX-512 RDM is suitable for operation more effiecient in bigger current ouput like wall washers and 0.1 million pixels – billion pixels project like theaters, concerts and buildings lighting.


Wish above simple words can help you understand the RDM.
