3.2.4 Frame Counter

Each message has an 8-bit embedded frame counter that changes on every data frame; this prevents frozen data
and data frame hacking.

3.5

System Parameters

The system parameters, including the system address and the selected RF channel, are set by programming the
TransKey. This is a removable radio frequency identification device (RFID) located inside the OCU and MCU. It is
programmed by the manufacturer.

Note:

Please refer to the separate 'Configuration Data' documents for the specific system parameter settings

of your system.
