• Zeus as REC Active follower on 500k bms can but no cerbo widget.

  I saw something similar, I just wrote it off as being a bug because I don't have a battery shunt attached to the Zeus.  I do have a smart shunt that I've drilled and tapped to allow the rec to...

  @Rick-admin thanks.  If Trond hasn't had any response either I'll start systematically shaking the tree once I'm back off this drilling rig.

  @Trond Røsvik@Rick-admin have yall gotten any traction with ARCO?

  Ok, that's disappointing, but not unexpected I suppose.

  Trond, have you tried to apply a "battery" voltage to the battery sense leads?  On mine they don't sense anything.

  Also, once it's been connected to a can buss it will ignore the battery sense.  I installed that as a backup to the can network and was dismayed to find the battery voltage measurement ignored...

  I've been speaking with an engineer (who I sense is new to Arco or the Zeus project).  But his name is written down on the boat and I'm on a drilling rig right now.

  Thanks Trond.  This sounds much like my experience.  I was approaching the "rip out the Zeus and replace it" phase. did you happen to try the REC at 250K and with the cerbo set to 250k b...

  @Trond Røsvik I'm on the newer/est version of firmware.  I should be back to the boat in a weekish.  I do know when I changed the comm rate with CANS the bms accepted the change.&n...

  @Trond Røsvik thanks.  I'm just blind.  That is what I tried.  Once I get back to the boat I'll try again just to be sure I didn't screw up my first attempt.

• Zeus as REC Active follower on 500k bms can but no cerbo widget.

  I did briefly try doing that (changing my rec to 250k and configuring the can for ve.can and bms) but didn't have any luck.  At the time I wasn't putting too much time into it as other project...

• Zeus as REC Active follower on 500k bms can but no cerbo widget.

  Odd, I'm nowhere near the boat at the moment, but that firmware seems to ring a bell.  Mine did show up on the cerbo as a Victron follower, with the can set to lynx bms ve.can but without the ...

• Zeus as REC Active follower on 500k bms can but no cerbo widget.

  Ok, glad it's not just me.  I did tell ARCO that their documentation sucked...they agreed.   I don't believe that the Zeus participates in DVCC while configured as a rec follower, but at...

• Zeus as REC Active follower on 500k bms can but no cerbo widget.

  I was told by ARCO that setting the Zeus to rec follower changed its comm rate to 500k. I briefly tried changing the REC to 250k but the cerbo didn't immediately recognize it.  Admittedly I d...

  Trond yes, I've got VE.Can port 2 configured for 500k LV BMS with the REC-A plugged into one of the ports, the other port has the Zeus connected with a 25' cat6 network cable and a terminator in t...

• Zeus as REC Active follower on 500k bms can but no cerbo widget.

  I've got a Rec active that's feeding a Victron system with a cerbo.  The Active is connected to one of the VE.CAN ports with the can set to 500k bms.  So far all good.  The Zeus is a...

• Number of inverter/charger devices, will 1 still allow the cerbo to control multiples?

  Great, that makes sense.  Thanks

  I've just purchased an Active, and am in the process of setting everything up in my garage before installing on the boat.   I'm not clear on the number of charging devices entry.  In my ...
