Agreed. Going "digital" is definitely a continuing customer request. Most customers don't know what a ground offset is and have a hard enough time understanding analog input & analog ground. Unfortunately, logging systems have varying standards. As you know, CAN has different speeds, identifier, & message structures. Serial is, in effect, just a loose term for do whatever you want in the aftermarket. I suspect J1939 is the simplest way to go but it will leave a lot of other users with only one CAN bus or a non configurable bus out in the dark still. It is a want but we will need to hit some further volume targets first.
In a related point, it looks like the AFRM is going on national backorder just as the season is coming on here. So, for those on the fence the AFR500 is available!
