does anyone know if their is a way for the pdm to hold the count of a counter after it has been powered down. for example, i have a loop around counter for an electric ebrake. 0 is disable ebrake, 2 is nothing 3 is apply and 4 is keep button light on. 2 and 4 are holders after a set time or current limit is reached. my issue I'm having is if i apply the ebrake it will hold the button light on and ebrake on. but if i cycle the ignition off and back on the ebrake stay active because with ignition on it cycles the counter to 2 which is an empty holder. but in order to get the light to come on stating the ebrake is still applied you must press the button again and it will move counter to 3 run ebrake calipers and the…

Need help with Ft700 can config. Can't download it. I have a Pdm 28 downloaded the latest version 1.3 Thank you

Hi folks

My camper van has a PDM 15 controlling the electronics which run from the leisure battery. (Internal lights, electric pump on the sink, fridge etc)

The leisure battery failed recently, so i had it replaced. It is now working, but there's no power to anything.

The blockage seems to be the PDM. I've connected to the PDM via the USB, and managed to establish a connection, to try and diagnose the fault. I seemed to be getting somewhere, but then i must have unplugged the USB it at the wrong time, because now the computer says "the USB device has malfunctioned" (or similar error) and when I look on device manager, it has a warning sign associated with that USB port.

When I try to connect the PDM, sometimes it works, and sometimes it seems to work, and then says "device unplugged" almost immediately.

I've restarted my computer,…

I’m triggering the starter solenoid from one of the 4 high current outputs. It sounded a little odd and quickly broke a starter. After installing another starter I video’d it in action and you could see playing back in slow motion it was oscillating rapidly. The only workaround I’ve found temporary is to set minimum on time to .2 sec but this is not ideal, as it causes the starter to hang on once the motor fires. What am I doing wrong? It’s a race car, 16v lithium battery.
