A. PRINTER I/F
Checks the printer I/F when the printer does not function properly. You need to
connect the printer prior to performing this check.
Connecting the printer buffer may cause an error. Therefore, connect the GLC and
the printer directly.
If no error exists, (ASCII Code: 20 to 7D<HEX> and A0 to DF<HEX>) will be
output (printed) and the message
OK
will appear on the screen. If an error exists,
an error message will appear.
B. SIO CHECK
Checks the RS-232C and RS-422 SIO lines for areas where communication
problems develop. In the menu, select which check to run. To run the check,
connecting the SIO cable is necessary. If everything is normal,
OK
displays. If a
problem exists, an error message appears.
