Yes, probably your cable is meant for connection to Victron, but we dont know that. You can see that by looking at the RJ45 connector. Is there cables on PIN 7 and 8? Or is there cables on...

Configuration and even more monitoring thru the Victron VRM system would be optimal. Download and upload of config file. But I guess that would be a bit optimistic.

I hear you.  Our Windows app was originally designed for BT support but I understand they couldn\'t get it to be reliable.  If they do, most of the code is already roughed in.  I hear they are work...

Ben, Much appreciate the detailed response. Here is where I am: just updated firmware to latest rev I will deactivate Overcharge altogether. I had to read up on Finish Charge to understand....

Michael,   Trond makes a good point here.  Wakespeed uses a different pinout than most devices such REC and Victron so you need to be careful as if you were to connect a standard Etherne...

Hey Rich, I am guessing that might be to power the RS485 to USB in the custom programming circuitry but you would need to contact REC directly to confirm.  On that note your programming software in...

I would like to connect a PC to the Active BMS using a USB-to-RS485 adaptor.  As a first step I examined the pin assignments for the DB9 connector.  These are shown on Table 5 in the user manual. ...

Its all in the manual. https://www.rec-bms.com/wp-content/uploads/2022/02/UserManual_ABMS_Victron_Wakespeed.pdf The command to set the canbus speed to 250kbps is: CANF 250 After that, y...

Hi Rick Thanks for your helpful reply I have certainly not done any of the communication settings you have detailed above. Which profile would you suggest that I use to do the initial inst...

Hey Mike, When I set up a system, I first install the default profile for my battery type and set my CANBus speed to 250K.  (Some people prefer 500K but I have seen some comms problems at the hi...

Hi, I have just built up my REC BMS and the WS500, I have connected up the alternator and the WS500 as per the instructions and I am not getting any field coil output, hence my alternator isn\'t wo...

Nice that you post all your settings. Looking at your uploaded files at 29 august. I see Battery Bat cap ovrd at 3.6 This means that the 3 amp (accept amp exit) under bulk , multiply 3,6 is 10....

If my set-up had been one and done, the USB would be fine. But I am still fussing and have had the covers (twin engine) off about ten times in the past week. And logging data is a challenge. An ext...

thanks, I should have rephrased all that about the alternators. My guess is, they are putting in as much as the batteries will accept. About the same current as when I engage my 3X chargers. (300A)...

Thanks for your quick replies.  Using the Oil pressure sensor is not an option because a real failure would then also \"activate\" the charge lamp giving the alarm system the same state as if the e...

Thanks Al, I will upgrade the sw today.

Gregory, Hello.  I have reached out to support to have then follow up to your question.  Please be looking for that and sorry for the delay.  (In short, all the phases are documented in the WS50...

Al, can you help out on this one? @al-thomason

Alternator Centric is an older term that I understand from WS is not being used anymore.  Basically it means control to the limits of the alternator, instead of the limits of the battery, and to do...

I have the same question and I cant see anywhere in the manual that discusses the twin engine/twin shunt issue. No idea what \"Alternator centric\" might mean. In my case, twin large case altern...

Jon, I have a similar issue: system drops to Float early. I dont think I am pulling amps down at the time. No luck getting any response from Wakespeed. ANy luck at your end?

No matter how I adjust the various settings in my custom profile I cannot keep my alternators at Acceptance level voltage long enough. The WS500s drop to Float at about 96% and 20A in. With my Fire...

It would be helpful if I could call up and export my custom profile settings in readable text. I am having some issues in setting up my system and i would like to have my settings reviewed by an ex...

Off the top of my head I was thinking you could use the tach wire from the alt to drive a relay that would basically give you an output whenever the alt was turning.  You are going to get a pulse o...

I guess you could partually solve this letting the WS500 Charge lamp output drive an small relay. Then you would have to use an \"Normal Closed\" output on the relay. This should give you the...

I have a setup with 2 WS500 connected to two ElectroMaax Cruiser High-Output 140A.  My boat has an alarmsystem that requires the traditional charge lamp signal (GND when alternator not running/faul...

You are right, with the US language setting it works. A little bit strange. Thx for the help.

The Android App has an function for updating FW. So far i have NOT been able to get this to work. Is there some trick to it?

Some customers are having issues with trying to update their WS500 to the new 2.5 firmware. There seems to be two potential issues the STM driver seems to have issues with USB3 ports and sl...

Thanks for sharing!  I will see if I can get this build posted to the REC-BMS-NA website in the next few days for everyone that might need it.
