Computer Diagnostics
TracVision 6 has been designed to provide diagnostic readouts
viewed on a personal computer having an RS-232 serial
communication port. If you are unable to isolate a system
problem, set up for computer diagnostics as described below.
System problems will most likely be found somewhere through
the diagnostic readouts.
The diagnostics procedure requires terminal emulation software
such as PROCOMM, Windows Terminal, or Windows 95/98
Hyperterminal. Use the settings appropriate to your application.
1. Connect one end of the PC cable to the DB9
connector on the front of the switchplate. Connect
the other end to the serial port on the PC (a 9-
pin/25-pin connector adapter may be needed for
some PCs).
2. Open the terminal emulation software and
establish the following settings:
• 9600 baud
• no parity
• 8 data bits
• 1 start bit
• 1 stop bit
• no flow control
3. Apply power to the TracVision 6 system and allow
the system to complete full initialization. Data
should be scrolling on the PC display to identify
any system problems detected. If no data is seen,
recheck your connections and the terminal
software setup.
4. After completing the diagnostic, shut down the
system.
