System Setup
The 2500 programming electronics receives CRC commands and sends
responses to the host computer through the RS-232C port labeled
“Programmer Port” on the back of the 2500. This is the only port that will
respond to programming electronics CRC commands.
To ensure correct operation of the 2500 port with the host computer, set
the parameters for the 2500 port according to the host computer
requirements.
Halting CRC Operations
To halt any command or any ongoing CRC operation, send one of the
following commands to the Programmer port (neither command requires
a
↵
). Both commands act immediately, terminating any preceding
command operation.
