Computer Diagnostics

TracVision Cruiser has been designed to provide diagnostic
readouts viewed on the TV screen (DSS only) or on a personal
computer having an RS-232 serial communication port. If you
are unable to isolate a system problem with the foregoing
troubleshooting tools, 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 Hyperterminal. Use the settings appropriate to
your application.
1. Connect one end of the PC cable to the female
DB9 connector on the end of the data cable.
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 Cruiser 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.
