RS-422/RS-530
The port checker uses the RS-232 software to check the RS- 422/530 ports. Some 422/530 ports support all RS-232 handshake lines but many do not. Therefore, when checking 422/530 ports, you should check the port after it is first installed and working properly. You will then have a record of how your 422/530 port initially tested in the file “ PORTCK.DAT “. Thereafter, if you suspect a problem with your port, you can run the port check and compare these results to the original results.
Special Note on B&B's RS-422/485 I/O Card, Model 422ICCR3: When using the port checker to check this IO card, your port checker jumper should be set to RS-530. When you run the port checker software you will get an RI (Ring Indicator) failure.
The port checker is not designed to test RS-485 cards. If your IO card is set up for RS-485 you will get multiple failures.
If you have an RS-232 to RS-422 converter and are using the port checker to test the output of the converter, you should be using the RS-422 portion of the port checker. However, it is important to note that, depending on how the handshake lines are handled, you might get handshake line failures. If the RS-232 to RS-422 converter is working properly, or if you are checking a standard RS- 422 port, you should not get a TXD or RXD failure. If they are working that test should pass.
Exiting the Test
After each test is performed, the software will ask if another test is to be performed or if you want to exit the port checker program. IMPORTANT: After exiting the port checker software program you should do a hardware reboot. The port checker software may have altered your system configuration registers that are reconfigured on each hardware reboot.
