3.5 Computer Diagnostics
TracVision 4 has been designed to provide diagnostic readouts
viewed on a PC 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 Windows Hyperterminal (or
other terminal emulation software, such as PROCOMM). Use the
settings appropriate to your application and follow the steps
below.
1. Connect one end of the PC data cable to the DB9
connector on the switchplate. Connect the other
end to the serial port on your 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:
• Bits per second: 9600
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
3. Apply power to the TracVision 4 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 for the correct COM port.
