Now as you send a command from the 1775–KA or the RS–232–C
device, ASCII characters will appear on the industrial terminal. Use
Table A.A to find the command bytes (DLE, FNC, etc.) that these
characters represent. You may not care what the actual numeric value is
for control characters such as DLE STX; on the other hand, you will
probably want to know the numeric value of DATA sent with a command.
Figure A.3 shows an example of a command as it might appear on the line
monitor, and how it is translated.
