PROBLEM SYMPTOM CAUSE SOLUTION
check pin 20 of peripheral to pin 5 of
Model 24SII DES and/or pin 11 on
parallel ports for continuity by using an
ohm meter to check resistance from end
to end.
Parallel cable
length
Parallel cable should not exceed 15 feet.
Use shorter length or higher-quality
cable.
Configuration
problem
Check baud rate, word size, stop bits
and parity on serial ports. It is best to be
at 8 word size and no parity. BayTech
does not recommend a configuration of
7 word size with odd or even parity.
