Echo DMX Scene controller voltage output on Echoconnect Bus

Greetings,

I recently installed a DMX Scene Controller and an Echo Inspire Control Station and also the 24V aux power supply.

I wasn't getting any power to the control station to begin programming. I went to the Scene Controller and metered 0V coming off the Echoconnect bus.

The power led is working, the DMX in and out leds are working and it was blinking red when there was no DMX present.

One note, there is only 22.9V coming from the power supply which is new. So I don't know if that 1v drop if affecting the output or if the controller is bad.

I assume there should always be +24v coming from the Echoconnect output, but I'm getting 0V.

I did buy the controller from Ebay; however it looks brand new with all the appropriate paperwork, heat shrink, tie-wraps, etc.

DMX is passing through the controller properly.

Thanks for the help,

Glenn

Hi Glenn!

It sounds to me like you might be missing the EchoConnect power supply. The Echo communication bus requires its own power supply to power devices. Some devices, like the DMX Scene Controller, require a separate 24V aux power as they draw more power than the bus alone can provide. The Inspire station doesn’t require 24V, but does require bus power.

Measuring 22.9V for the 24V supply is fine! That’s still within the acceptable range there.

Hope that helps!

Thanks for the response.

I have the Echo APS 2 powering the controller. So I would need a 2nd separate power supply just for the Echoconnect bus?

I assumed the controller would have passed the 24v through it to the bus.

Hey Glenn,

That is correct. The E-APS2 just provides 24V Aux power. The E-SPS is a separate product that provides station bus power. Alternatively, the E-SPS-DIN can provide both station bus and aux power from a DIN rail form factor.
