Troubleshooting

If you are unable to communicate with the card from your software:

1.Consult your software manual to make sure it supports the address and interrupt that you have configured.

2.Double check that the address and interrupt are properly set.

3.Try another software package for troubleshooting. Download SimpTerm (DOS Terminal Emulator) or Comtest (Windows Terminal Emulator) from B&B Electronics’ web site. SimpTerm and Comtest are shareware Simple Terminal Emulators which can be used to vary the setup of any serial card. Both can be downloaded from the following site location:

4. Troubleshooting with a Loopback Test.

Load Simpterm or Comtest on the test PC. When loading Simpterm you must set up the port address and IRQ you have set on the B&B Electronics serial card.

Jumper TD to RD on the DB9 male connector located on the serial card. You may have to make a “loopback connector” in order to do this. This is done by jumpering pin 2 and pin 3 of a DB9 female connector and plugging it into the DB9 male port on the serial card.

To test the RS-232 handshake lines you can also jumper RTS to CTS and DTR to DSR. When you raise the RTS line you should see CTS also go high. When you raise the DTR line you should see DSR also go high.

Send data from the Serial Port (B&B Electronics serial card) and see if the data is echoed back to the port. When a character is typed on the keyboard you must see a duplicate character after the first character to verify that the same character was received. Perform this test on all ports of your serial card to verify the ports can (or cannot) transmit and receive data.
