Troubleshooting
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:
1. Make sure all PC/104 cards are removed from the PC-510. This ensures
that other cards are not interacting with the PC-510.
2. Change W2[1-2]/W3[1-2]. Depending upon your current ROM enable
and jumper state, these jumpers disable the video section. See the
Console devices
chapter for further instructions on how to enable/disable
the video BIOS device.
3. The VTC-20F serial cable turns the PC-510 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-20F serial cable is connected to J7 of the
PC-510.
4. Make sure your power module pr5V (+/-0.25V) and at least 2.5A
of current.
5. After verifying the above conditions, you can monitor voltage levels by
connecting an oscilloscope between the TxD* line on J7 (pin 5) and
ground. After powerup, you should see a burst of activity on the oscillo-
scope screen. The voltage level should switch b/-8V. This test
verifies that the CPU is active and that the transmit from COM1 is
functional.
Garbled serial console screen activity
If you do get activity on your console screen but the message is garbled,
check the following:
1. Remove USESETUP W2[9-10] to force 9600, N, 8, 1 for COM1.
2. 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.
3. 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-510: 9600 baud, 8 bits, 1
stop bit, no parity.
