5. Communication Protocol
The controller communicates with the host by serial communication via RS232 (57.6K, 1 start bit, 8 bit, 1
stop bit). The controller receives the data via an interrupt routine that places the data on the circular receive
buffer. When the controller detects data in the circular receive buffer, at Step 5G, it reads one byte and
executes the following:
When the controller executes a subroutine and expects additional information:
Commands are one byte in the range of 20H to 2FH and 01H and are transmitted in hex format. The proper
format for all command options and data is specified for each command.
Commands to the controller
Command to reboot the controller
Command to check communication
Command to download a Legend block
A. If the byte is a command, the controller transmits a 61H and executes the subroutine for the command
B. If the byte is not a command, it is ignored.
A. A timer is set. If the expected data byte is not received in 50ms, the controller transmits 6EH and
B. If the byte value is not acceptable (invalid range, option, etc.), the controller transmits 6EH and
The command reboots the controller to power-up state.
The command is used to check if the controller is on-line.
The controller transmits back 61H to the host.

and upon completion of command the controller transmits 79H. All of the commands are explained in
