Re: Bypassing Boston Acoutstic amp on Jeep REC w/ Nav

Hi CHACHY, The BA Amplifier has only 1 pair of stereo inputs, usually driven by the 'rear' output of the new headunit. The fade ( front to rear ) is controlled over the CAN-bus by the factory radio. So, with an aftermarket unit, you'll have no fade control. I'm not familiar with any ability to corre...

Re: RV-C connection for SeeLevel tank monitor

Ooh... you could also get a small e-paper display and put it in the kitchen, to display actual % levels (not just 4 segments).

Just ideas to spin your propeller :D

Re: RV-C connection for SeeLevel tank monitor

Nicely done, JimmyM. Some thoughts on other features you may consider -- code this up on an ESP32 (or esp8266) with a small web page and MQTT support. This way, you could always display the tank level on any Web browser, or feed it into home automation or other alerting systems ( Thinking HomeAssist...

Re: RV-C connection for SeeLevel tank monitor

FYI -- For any other off-spec things you find, there's probably an entry for it in the rvc-spec.yml file from rvc-proxy project:

Re: RV-C connection for SeeLevel tank monitor

Hey JimmyM, congrats on the progress! The 0FECA DGN is an off-spec duplicate of 1FECA which is a diagnostic message ( DM_RV ). Completely safe to ignore.

Re: RV-C connection for SeeLevel tank monitor

Hi JimmyM, the Pinout starting from the release clip side is:
Release clip -> (12v) (CAN-Hi) (CAN-Lo) (Gnd)

The cable I use, that produces color pattern:
Release clip -> (Red) (White) (Green) (Black)

Re: RV-C connection for SeeLevel tank monitor

Hi JimmyM,
The connector is a 3M 4 pin connector... Here's a link to the item on Mouser:

Re: RV-C connection for SeeLevel tank monitor

FYI -- for tank level, that is covered in section 6.28.2 of the PDF starting on page 177:

Re: RV-C connection for SeeLevel tank monitor

Also... for my specific use ( turning off my RO water production ), I didn't want to stop at the first sign of 100% full on the Fresh tank. Thus, why I put the counter in place and only turn off the RO when there have been 60 consecutive full readings. This is because the levels are rarely triggered...

Re: RV-C connection for SeeLevel tank monitor

Hi JimmyM, Yes, buf[0] == 1 would be the black tank. and == 3 is the Propane level ( if used ) The tank level is provided as a function of how many steps are active, out of how many steps are possible. For example, due to tank height, you may need to cut the sensor down from 20 segments to 18 segmen...

Re: RV-C connection for SeeLevel tank monitor

Ya, the RV-C spec provides details on how often each type of message should be broadcast. But since it is broadcast, you simply monitor the CAN-bus for the messages you're interested in, and process as needed. The arduino code show good examples of all that, specifically the tank level readings.

Yep, that's what comes stock on Tiffin Motorhomes. Thus, it's what my code was written for.

Ah, one catch.. Amp bypass, not using the inbuilt amp.

Re: 2005 Dodge ram srt10 radio/amp canbus

Looks like they have the details -- I added your truck, picked a head unit, and it suggested the extra parts needed for the install.

Re: RV-C connection for SeeLevel tank monitor

OH, one other thing I should point out.. I ended up modifying the mcp_can.h library to accommodate the 8Mhz chip on the cheaper CAN-bus interfaces. In case you're using one of those.. and the mcp_can library hasn't been updated upstream, here's the changes needed: Inside mcp_can.cpp, under the INT8U...
