PiCap and LOR CMB24D 24 Channel Dumb RGB Board
« on: February 06, 2019, 07:58:35 PM »
So continue to run into challenges with getting these two to cooperate

Hardware side:

PiCap is jumpered to DMX and I am using the RJ45 Port on the PiCap
Normal piece of CAT6 (no crossover)

CMB24D is jumpered to DMX and switches are set to DMX70


FPP Side:

Other tab - Active, DMX-Open, Start Channel 3133, Channel Count 24, Port ttyAMOA
Channel Output - Line 10, Active, FPP start=3133, Universe 70, Size 24, Unicast, same IP as PI



Light on CMB24D blinks red, when I click "enable test mode" it goes solid, but no lights work

This set-up worked off a F16 last year with no issue.   I also have this same set-up three times over and none seem to work off PiCap, CMB24D works fine using LOR Hardware test (after moving jumpers to LOR)

Is this FPP v2.x?

I have tested pixelnet with FPP v2.x but not DMX.  I will try to test in the next couple days.

Forgot to include - three setups doing the same.  Two on 2.6 and one on 2.5

Not sure if this info helps but I got DMX output from the PiCap working great using FPP 2.6.  I have two DMX floods directly connected to the DMX output on the PiCap using this wiring diagram:

I just tested DMX output on a FPP v2.6 system with a PiCap talking to a 3-channel DMX controller and it worked correctly.  I'm thinking it must be your jumper settings or cable.

If you are using a LOR controller, don't you have to use the LOR jumper settings to get the signal on the right pins that the LOR controllers are using?  The LOR vs DMX vs REN jumpers are for the RJ45 pinout, not the protocol going over the wire.

make sure that you have this check,  Always transmit channel data:
this on the FPP Global Settings page.

Some DMX devices need the ground as well.  Connect the XLR pin 1 to RJ45 pin 7 and/or 8. (Caution- doing this from memory as I am away from my notes.   ::) )

Sequencers: Vixen3 and xLights
Players: FPP and xSchedule Controllers:  Renards - SS24/SS16; E1.31 - San Devices E682 - Falcon F16, F4, F48 - J1Sys - DIYLEDExpress E1.31 Bridges.  Much more!

I don't have any LOR stuff so I'm probably wrong, but I thought LOR uses different pins ... even if its running DMX protocol

Thanks, it is all connected through standard CAT6 Cables

Okay, that's good then - so probably hardware side......

I am using the DMX jumpers on the PiCap and this is a DC LOR board so it also has jumpers to go between LOR and DMX (they are jumpered to DMX as well).  I agree these jumpers are all about the pinouts on both boards, not the protocol.

I have this set-up three times over - so doubt bad cables or boards on all (plus they work from LOR dongle)

it does for sure, but this is one of their DC boards and has jumpers to move the wiring config over to standard DMX setup (like on right)  So there shouldn't be a need for a crossover cable as the PiCap is also jumpered to DMX.

This was not checked on any of them.   I have updated all of them, but still no luck.   I will rejumper one back to all LOR and see if that does anything.   The importance of this checkbox being ticked makes sense.

I use this setup for my singing pumpkin and remember having trouble getting it going but can not remember for sure what the issue was.  It seems like it was something with jumpers that did not make any sense.  I have not messed with since I got it going. I will look at it tonight.

Rejumpered to LOR on both and "heartbeat/sync" light on LOR board works, but still cannot get a test from FPP to run.
