Operational Overview
The MAP450D Operator Interface Terminal (OIT) provides the human-machine interface
between an operator and an ASCII compatible computer or host controller. Any
controller that is capable of sending and receiving ASCII characters through a serial port
can potentially communicate to the MAP450D.
The MAP450D receives and sends simple ASCII character strings. It accepts:
printable ASCII characters — which immediately display on the OIT
non-printable ASCII control characters (Control Codes) which directly affect the
OIT’s display
and special ASCII character combinations (Control Commands).
Control Commands cause the OIT to:
modify the OIT’s configuration parameters
echo back text
poll or clear the OIT’s buffers
display one of up to 500 predefined messages
or sound the OIT’s internal buzzer
