• If you have had a system for years, and/or it is used in an environment with a
corrosive atmosphere, you may want to periodically check and clean the contacts in
the system - the backplane connector contacts and the mating gold fingers on the
cards; the power supply Molex connector contacts; the RJ2EX connections to the
phone lines and transmitters; and perhaps even the socketed ICs on the cards.
• Check with us occasionally for new features and capabilities that may be useful to
you. The best way to do this is to make sure you subscribe to the Zetron Advantage
newsletter.
Troubleshooting the Office Computer
The office computer environment is the hardest for us to predict and control. Problems
vary from incompatibility with modems to cables not correct for the application.
Installation errors are reduced by using special installation programs so the installer need
not know much about DOS, but problems still can occur. The following table contains
information on isolating communication problems between the terminal and the office
computer.
