8. Troubleshooting
Problem:
The mouse works in the configuration program, but it freezes when I
load run the MCNRCD Remote Comparator Display program.
Using the wrong COM port
This problem will happen if you specify a COM port that conflicts with your
mouse in your command line switch.
To recover from this, exit from MCNRCD and edit your CONFIG.SYS file.
Specify the proper COM port on the device driver command line. Refer to section
5.2 and use the /Pn option.
Conflict with the COM port IRQ
This problem will happen if the interrupt request number (IRQ) being used by
device driver is also being used by another device in the system.
To recover from this, exit from MCNRCD and edit your CONFIG.SYS file.
Specify, on the device driver command line, an IRQ number for the COM port
that does not conflict with any other device in your PC. Refer to section 5.2 and
use the /Un option.
Problem:
The system doesn’t respond.
•
Check the network and power connections. Also refer to the troubleshooting
sections of the MCN System Manual and the Hardware Reference manual for
the HIB and the Comparator I/O Modules (CIBs and AIBs).
Problem:
When MCNRCD is initializing the HIB, I get the HIB communications
failure error message.
•
Verify that the HIB is connected to the proper COM port on the PC.
•
Verify that the baud rate specified on the MCNRCD command line matches
the settings of the HIB’s OPTION A switches 1, 2 and 3. If not, change the
command line baud rate setting or change the HIB’s baud rate switches and
reset the HIB.
•
Verify that the HIB’s OPTION A switch 5 is in the DOWN position if the HIB
is connected directly to the PC or UP is the HIB using modems. If not in the
correct position, change the switch and reset the HIB.
