Looking for an example of Checksum Calculation for sending commands to HP-1 via the serial port.
Prior the the HP-1 Checksums were not required for serial port commands sent.
Example:
I want to send this command (from the protocol doc) to the HP1 via serial port.
RMT MODEL<cr>
I am calculating the checksum incorrectly apparently since I am receiving a response of ERR 242 from the Home Patrol.
Could someone provide an example for this command so I can figure out what I am doing wrong?
I tried as follows:
R - 82 + M - 77 + T - 84 + M - 77 + O -79 + D - 68 + E - 69 + L - 76 Total 612
I also tried 625 (612 + 13<cr>)
The following all result in ERR 242 from Home Patrol
Sending RMT MODEL 612<cr> or RMT MODEL, 612<cr>
Sending RMT MODEL 625<cr> or RMT MODEL, 625<cr>
Any help would be appreciated. Also what does the Serial Port for the Home Patrol Default to when selected and how would I change the Home Patrol Baud Rate it uses when the Serial Port is connected?
Thanks in advance.
