Code Check
Code Check identifies the tablet’s firmware version. It does this by issuing a number called
the checksum, to the host. Each firmware version has a unique checksum.
We recommend that you record the checksum when the unit first arrives and periodically
thereafter. The checksum should always be the same. A change indicates a change in the
firmware.
The checksum is in a six byte format: .#HHHH
HHHH is a hexadecimal number in ASCII. This is the format, regardless of the report
format being used by the tablet.
