and using this determine the function of each location.
Details of Device and how to use it to follow later.
No soldering of Logic Board Required.

obtained form Pin 1 of CN2 (connects to front panel) using sewing needle
Unknown means I haven't decoded it's purpose yet
* Denotes default value on Factory reset unless otherwise stated for each firmware..
I've tried changing the unused locations to something other than their default without effect so far.

Where format above appears as LLHH then each half is converted from Hex to Decimal seperately and then swapped.
Using the default entry for Parental C.C
which is for instance 5355 (LLHH) LL is 53 Hex and HH is 55 Hex.
53 Hex is 83 Decimal
55 Hex is 85 Decimal
LL and HH are swapped so code is
85 first followed by 83 - complete code is therefore 8583 decimal
