Computing the Checksum
The checksum is a simple arithmetic sum of the 7-bit values of all characters preceding it. The checksum reported is the
least significant 12 bits of this summation, converted to BCD ASCII.
Checksum Example:
COMP1
COMP1 enables the OSMAC Base Station to interface with any device that can output RS-232 data . All data entering
the serial port is sent to a pre-set satellite. The reception of a <CR> will initiate transmission of the command.
Manual Entry of a Command
COMP2
COMP2 enables the OSMAC Base Station to interface with any device that can output RS-232 data. It has the added
capability of selecting specific satellite or satellite groups to transmit the command.
All data entering the serial port is sent to a pre-set satellite. The reception of a <CR> will initiate transmission of the
command. If the last <CR> is not sent within 15 seconds, the OSMAC Base Station will abort this transaction, and begin
waiting for a new <Satellite #> entry.
