Is there a reason why the XC2x family of modules is missing +BAT diagnostic channel? I'm wondering if its a hardware limitation as the XA2 (below) and other modules appear to support it:
My customer needs to know the value of supply voltage on XC21 to read out on the master display. Unfortunately it needs to be a live readout rather than a digital flag if the module was to drop comms due to a low supply voltage. I will place a simple voltage divider circuit in if there is no workaround possible within the software but thought I would check first.
