2.8 Checking Out the System
Now that you’ve installed the TracVision G8, you need to verify
that the system functions properly. Check the system startup
routine to ensure that the system is operating within normal
parameters.
To view the startup routine, connect a PC to the MCU’s
maintenance port. This procedure requires Windows
Hyperterminal (or other terminal emulation software, such as
PROCOMM). Use the settings appropriate to your application.
1. Connect one end of the PC data cable to
the DB9 maintenance port connector on the rear of
the MCU. 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 G8 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.
