PictureTel III ISA manual Starting the DOS Configuration and Diagnostic Program

6-2CHAPTER 6: WINDOWS 3.X TROUBLESHOOTING

Diagnostic tests are divided into three groups:

■The Group 1 tests check the physical components, connectors, and circuitry on the NIC.

■The Group 2 Network Loopback Test (for the 3C509B-TPC and COMBO NICs only) checks to see if the NIC can transmit and receive data through the coaxial transceiver.

■The Group 3 test (the Echo Exchange Test) tests to see if the NIC can transmit and receive data while on the network.

If the NIC passes the group tests successfully, the NIC is functioning correctly. If the problem remains, look at cabling, software, driver configuration, and issues that can affect network functionality.
