ASCII OPERATING COMMANDS

ASCII protocol uses the ASCII character set to transmit and receive commands between an ASCII device (such as a personal computer or
ASCII keyboard) and the CM6800E.

The ASCII protocol communicates in a standard asynchronous, byte-oriented protocol that includes: 1 start bit, 8 data bits, 1 parity bit (odd
parity), and 1 stop bit. The default communication rate is 9600 baud.

A lowercase “a” ends each command. The ASCII translator acknowledges accepted commands and rejected commands with the following
responses:

AKa

command accepted

NAa

command rejected or the ASCII translator does not recognize the command

If the command requires a numeric value, enter the number first.

Table I provides examples of ASCII commands. Table J lists all of the commands.
