Wireless echo back test
The wireless echo back test verifies the correct operation of a device on the wireless network. Because this test loads a diagnostic program into the card, ensure that all lines from the communications I/O adapter are varied off before running the test.
- RS-485 cable connection
- Radio connection (that uses the system configuration)
- Radio connection (that uses a test configuration)
The Echo back test on RS-485 cable connection verifies communication to any device on the RS-485 wired network. If this test completes successfully, the adapter and RS-485 wired link are working correctly. If this test fails, run the I/O adapter tests in the order they are listed on the display to further analyze the problem.
The Echo back test on radio connection using system configuration verifies communication to any device on the radio network by using the configuration for the line selected. If this test completes successfully, the adapter and radio link are working correctly. If this test fails, run the Echo back test on radio connection using test configuration.
The Echo back test on radio connection using test configuration verifies communication to any device by using a test configuration. The device must be within radio range of the antenna that is connected to the Wireless LAN Adapter card. If this test fails, run the I/O adapter tests in the order they are listed on the display for further problem analysis. If this test completes successfully, the adapter and radio link work successfully with the test configuration. If you performed this test after an Echo back test on radio connection using system configuration test failed and this test passed, a configuration problem exists.
