I have got myself a couple of the Alpha Panel Layout panels for NCE and Roco and I have connected one of them to my Z21 with an RJ12 cable for LocoNet  but the blue power LED is not lighting. Have I missed a setting or something? Any help greatly appreciated

John

Are you sure it is meant to work with the Roco Z21 Loconet port? It doesn't actually say that in the documentation (such as there is)

Hi Iain
I bought them because the card says "Also works great with Roco" but perhaps that is not the full story. I will email support for some clarification.
Thanks for the reply

They do work very well with Roco, but you do need to connect them as we clearly show in the instructions, and that is clearly NOT to the loconet port.

Plugging digital things together is not wise unless you do read the instructions first.... for example the +/- 12v power wiring in a loconet RJ12 socket is different to the power wiring in the Roconet RJ12 ports... even though the connector is the same. Damage MAY happen if you connect wrongly... and damage x wrong connection is not covered by ANY warranty on any product in any field!

The best approach with Z21 is via an Alpha Shiffer into the sniffer port as then the Z21 display will also repeat what the Alpha central does. A perfect integration. (same with ESU ECoS)

I am talking about the DCD-DAP panels . quote Alpha-Panel is a universal command bus extension. I should have been clearer but I had not noticed the part number until this morning.

Same applies in relation to panels.

The wiring configuration is different for Loconet even though the connector is the same. Loconet uses a very different pin arrangement to Roco/lenz/NCE etc. To use Alpha Panels ou will need what are listed as digitrax adapters if you want to use these panels with a loconet bus successfully.... and have the switch in the correct position. I feel it would be easier to use original loconet panels really.

Ahjay,

Might it help if you were to say in the instruction which Roco ports that it will work with? As an example the Z21 has Xpressnet (X-Bus), Roco Bus (R-Bus), Loconet (L-Bus) and Booster Bus (B-Bus) ports all of which will take the RJ12 connector.

Which bus port would this work with?

All except Loconet. Systems evolve all of the time, and exceptions will always exist. Alpha panel is a natural fit for most of them... Most brands inclusing us sensibly use a standard RS485 bus wiring that is common across digital devices in many product areas.

The problem child has only ever been Digitrax which specified its bus wiring differently for no really useful reason that I can see.... not a problem except they did not also take the logical and sane path of using a different connector as well. Fits well in a way as also, the Digitrax waveform would never pass standards either... On every one we have tested it has always had a weak chin in its square wave that is well outside standards specification.

Should add. The difference between Xbus and Rbus or NCE for that matter is zero in the wiring. It is only the digital handshake that differentiates them, much as various computer printer drivers are only different because of a proprietary handshake within the code.

Thanks very much for this information, I am wondering if I would be better off selling the DR5088RC and sticking with the Roco Detector and use the CAN bus.If
anybody is using the Digikeijs unit can you let me know if it is working satisfactorily?

Regards
John

I have 5 x DR5088RC and they all work perfectly for me 🙂

Thanks Iain that helps.
one of the unknown unknowns now known?😊
