Troubleshooting & Maintenance

Troubleshooting & Maintenance  B

If you encounter problems when installing or using your
IOLAN+, try the suggestions given in this chapter.  Hopefully,
the problems can be solved quickly, otherwise contact your
distributor or Chase support.   Email or fax as described in
section 1.3, 

Getting Support.

B.1 Terminals/PC

Problems

If your terminal or PC connection is not working properly,
symptoms are usually no output at all, 'garbage' on the
screen, loss of characters or ports locking.  Here is the
common solution checklist to these problems:

Cable error 

Replace the cable with a known good one or test the cable
ends.  Check the wiring against Appendix C, 

Cabling Guide.

This is the number one problem.  It is helpful to have a null
modem cable and a RS-232 mini-tester.

Port settings
incorrect

Check the set-ups of IOLAN+ and the terminal ensuring that
they are the same at both ends.  Check parity, bps rate, flow
control, data bits and stop bits.

No flow control 

Set flow control to be the same at both ends and ensure that
the cable installed is capable of supporting it.

Port flow
controlled

It is possible that an 

XOFF character has been received by

mistakenly typing 

 or other condition.  Power the

terminal off and on and type 

.

Wrong flow
control

If the 

XON and XOFF characters are configurable on the

terminal check that they are set to 

 (0x11) and 

(0x13).  If the application you are using is transferring binary
data then software flow control cannot be used as some of the
binary data may be interpreted as flow control characters.
