SOLVING PROBLEMS
This Section helps you solve common problems that might arise when installing or
using your protocol converter. There are three major areas of difficulty:
• Missing printer output
• Incorrect printer output
• Host communication problems
Missing Printout
If the installation has been done correctly and you still don’t get printouts as expected,
check the following steps for problem determination.
Q: Is the POWER indicator on?
A: No: Your printer can’t supply the protocol converter. You must use an external
power supply.
Q: Is the attached printer on line (ready)?
A: No: Set the printer on line (see the printer manual).
Q: Is the printer correctly attached?
A: Make sure the protocol converter printer cable is connected to the proper port. If
your printer has both parallel and serial input ports, the printer must be set for the
printer cable type (parallel/serial) you are using.
Q: For serial attached printers: Are the serial parameters correct?
A: Make sure that the baud rate, stop bits, parity and word length settings match your
printer settings. If XON/XOFF protocol is used #039 PC-Host Time-out must be set
to 0.
Q: System printouts: Is the SYSTEM indicator on?
A: No: The protocol converter isn’t correctly connected to the host, or the power-up
routine has been disturbed. (See “Host Communication Problems” on page 73)
A: Flashing: The protocol converter is in Test Mode. To exit set the rotary switch to
‘9’, or switch the protocol converter off and on.
Q: PC printouts: Is the PC-Host Sharing configuration correct?
A: Refer to Section 6 and the User’s Manual.
