Hi Brad, I can't help much on the Maxim side, but regarding the AP V2 driver, I'll mention two things:
I'm sure you are aware, but just in case, the pier side is displayed on the driver's window just above the direction buttons.
You can verify in the log files with a search for :pS# (tell the search to match case). The response is coming directly from the GTOCP5, and will be what the driver reports to all other software.
