Chapter 22:
Troubleshooting
If your system is not working properly, check the following items.
No screen activity–checking console serial communications
If you do not get the sign-on message after bootup, check the following:
n
Make sure all cards except the PC Microcontroller are removed from
the card cage. This ensures that other cards are not interacting with
the PC Microcontroller and that a video card is not installed.
n
Remove the jumper from the “S” position at W1.
n
The VTC-9F serial cable turns the PC Microcontroller serial port
into a 9-pin AT serial port. Make sure a null modem adapter is
installed on the other end, and that the assembly is inserted into the
proper serial port on the PC. Make sure the VTC-9F serial cable is
connected to COM1 on the PC Microcontroller.
n
Make sure your power module pr5V (+/-0.20V) and at least
2.5A of current.
n
After verifying the above conditions, you can monitor voltage levels
by connecting an oscilloscope between the TxD* line on COM1 and
ground. After powerup, you should see a burst of activity on the
oscilloscope screen. The voltage level should switch b/-8V.
Garbled console screen activity
If you do get activity on your console screen but the message is garbled,
check the following:
n
Remove the jumper from the “S” position at W1 to force 9600, N, 8, 1
for COM1.
n
If you are using PC SmartLINK, make sure you have configured the
software for 9600 baud and have selected the correct serial port for
communicating with your PC. Refer to the PC SmartLINK manual
for information on selecting the baud rate.
n
If you are using communications software other than
PC SmartLINK, Octagon cannot guarantee the operation. Make
sure that the software parameters are set to match those of the PC
Microcontroller: 9600 baud, 8 bits, 1 stop bit, and no parity.
