Congratulations! That is SPECTACULAR! I'm so jealous you have a running generator you can vampire into! I have the full 1939 spec, so I'll see what I can do about generating some of these words with values and fire them into the datastream through the PCAN-Explorer!

Good morning! Sorry for the delay. Can confirm that those are the main words I see as well. I also get retransmit requests when I switch my ENG ID in and out of modes that use CANbus, just before it declares degraded CAN bus. Does your capture give you any information about how often each of...

Good afternoon, sorry for the delay. So if you have a ground on J3-LL, your DCS should think that it is connected to a 30 kW, 120/208 VAC, 60 Hz system. Is that accurate? I've just put a meter across J3-K and J3-L, and can confirm that I see approximately the same results. My interpretation...

Based on the oscilloscope rate of 4 microseconds per bit, I chose 250kHz and it seems to be happy with that :)

Ah... fair enough, thanks for clarifying :)

I have a CAN to USB adapter from Gridconnect, PN GC-CAN-USB IPEH 002021. I'm also using a 30 day trial of their PCAN-EXPLORER 6. My 485-USB is just one I had laying around from an old security system install, no PN visible. Kloppk, I'm very interested hear what data the ECM replies with from a...

ah... an intriguing possibility, a CAN-enabled unit may not converse via 485. Standby. Can confirm that having J3-LL grounded is compatible with RMT access... Lmk if the issue persists after connecting Pin I to your serial adapter, I'll pull my DCS back off the whole harness and see if it's a...

On the Remote connector I have C and D connected as discussed. I also used pin I which is connected to the DCS' return circuit to provide a RTN to my 485-USB adapter. I have been able to get the remote software working (the RMT icon), but I had to set up my 485-USB adapter serial port in the RMT...

Nice! glad to see it powered up! The CAN data comes out the back at pins J3-K (CAN HI) and J3-L(CAN LO). The RS-485 pins on that front REMOTE connector are at C (485 HI) and D (485 LO). Thanks to your help, I'm just getting the remote software to pull values from the unit and display them in the...

Excellent news, glad to hear it's behaving as expected! Have you seen/heard anything from IceScythe or Kloppk in terms of their CAN adventures thus far? :)

100% correct. Do you know the make/model of your power supply?

Oh! excellent, I must've misunderstood your message due to the remote auto-capitalization in my first message. Just finished trial here, yanked it off full harness and connected only 2 things: +28VDC to J2-A and RTN to J2-f. When I pulled out e-stop and turned to P&R Main, it turned on the...

Hmmm. I'll pull mine off its harness and just check big A and little d to make sure I'm not forgetting anything from my original hook-up... Looking at the P2 pin out, it's unlikely that any damage was done, do you happen to remember if it was all 3 pins (Big D,E,F) or just one? So far ,I've...

Good morning! By any chance is the E-stop pushed in? On mine I have to pull out the E-stop and set rotary switch to either run/prime aux or run/ prime main. Also, do the panel lights respond to pushing the panel lights button? That might tell you if it's paying attention to inputs.

Apologies, apparently it auto-capitalized. It should be little d,e,f :)

Good morning, and apologies for the delay. As I mentioned, I only have the DCS itself and am therefore simulating the current draw of the contactor, fan relays, etc. The electronics/display of the DCS itself, however, have never drawn more than 0.75A @ 28 VDC, so based on my experience you...

Other than waiting for Cummins to approve the request, is there any legitimate way to acquire the inPower software?

I have a 1939 transceiver IC that I pulled from a different system, so yes, I can visualize / decode the stream on an oscilloscope, and I have a CAN/USB adapter arriving hopefully today.

Can confirm that ABC at 24 to 28+ and RTN at DEF will power up the DCS and that depending on selection made by the Engine ID switches it will live up the 1939 at K and L. it shouts into the abyss for a timeout period and then declares 'CAN bus degraded' . I ONLY have the DCS, so lmk if you want...

Thanks again for the assist. I know you, Icesythe7 & R1ckyb0nd moved out of this thread to keep it from growing uncomfortably large, but how is the 1939 effort moving along? tackling the CAN bus interface will be my next challenge :)
