Enttec Splitter RDS4 - RDM Problem

[RenZO]

Hello,

I made test with the Enttec Splitter RDS4 : RDM doesn't work for me.
It is this product :
http://www.enttec.com/index.php?main_menu=Products&pn=70037&show=description&name=rds4

Let's see, I try with RDM-TRI as controller and DMX-TRI as responder.
First, I plug a direct cable between both. It's OK (Discover/Get/Set).

Then, I plug on the splitter : Timeout. If I run discover again,
nothing.
But the RDS4's rdm led blink when i send requests.
On get request, both leds blink on both TRI.
On discover, tx red led blink on RDM-TRI and rx green led blink on DMX-
TRI (with direct cable, both leds blink on discover).

-with direct cable-

dmx@voyage:~$ ola_rdm_discover -u1 -f
6864:000000cd
dmx@voyage:~$ ola_rdm_get -u1 --uid 6864:000000cd manufacturer_label
JESE Ltd. GB

-then plug on splitter-

dmx@voyage:~$ ola_rdm_get -u1 --uid 6864:000000cd manufacturer_label
Error: Response Timeout
dmx@voyage:~$ ola_rdm_discover -u1 -f
dmx@voyage:~$ ola_rdm_discover -u1 -f
dmx@voyage:~$ ola_rdm_discover -u1 -f
dmx@voyage:~$ ola_rdm_get -u1 --uid 6864:000000cd manufacturer_label
Error: The RDM device could not be found

-plug a direct cable again-

dmx@voyage:~$ ola_rdm_discover -u1 -f
6864:000000cd
dmx@voyage:~$ ola_rdm_get -u1 --uid 6864:000000cd manufacturer_label
JESE Ltd. GB
dmx@voyage:~$

On OLA debug, it was :

Is there something to do ?

Which mode is the Enttec splitter operating in?

The splitter operates in RDM mode (that's why its rdm led blinks).
Anyway, I've tried in all modes without success.

When doing full discovery request, in RDM mode, only rx led blinks on
DMX-TRI (responder). But in bypass mode (which acts as a simple
splitter), both tx and rx leds blink on DMX-TRI (responder). So, we
could imagine that rdm processing of this splitter makes change on the
sent request, which isn't understood by the responder. Maybe it could
work with another devices.

I'd get in contact with Enttec and see if they have any ideas.

Enttec told me to monitor the dmx signal, but I don't have
oscilloscope right now.
The good news is I've tried with an IST Quad driver, and RDM works
through Enttec splitter :)

If you could make it to the UK plugfest this would be good to debug.
Hamish will be there and I suspect he could find the problem pretty
quickly.
