: Troubleshooting
If you have any trouble starting your system after installing the card,
the card may not be properly seated in the slot. Remove and re-
insert it or try a different slot. Check BIOS is set for PnP OS.
If you are unable to communicate with the card using your software
and hardware devices:
1.
Check your pinouts. In RS-422 or RS-485 mode the "A" lines
should match your "A" or "
−
" lines. "B" lines should match your
"B" or "+" lines.
Note: RS-422/485 pinouts are non-standard.
2.
Use the ComTest program provided on the Disc with a
loopback to check the card. Double-click on the ComTest folder
to open it.
3.
Run Setup.exe to install COMTest on your program menu
under B&B Electronics.
