    - To Perform a PCH Tx/Rx Test
      The PCH Tx/Rx test allows you to test the various serial communications ports on the control panel. This test helps to diagnose communication problems with external devices that you may be having on a particular serial communications port on the control panel.
    - To Perform an LVDS Test
      The Low Voltage Differential Signalling (LVDS) test allows you to test the various communications between the Panel Communications Hub (PCH) and all the Panel Module Controllers (PMC) installed on the switcher. This test includes both internal and external modules.
    - To Perform a Tally Test
      The tally test allows you to test the standard parallel tally system of the control panel. A Tally Test Box is required to ensure that the tally relays are operating properly. The number of tallies you have available to test depends on whether you have the Extended Tallies option installed.
    - To Perform a PCI Bridge Test
      The Peripheral Component Interconnect (PCI) Bridge test allows you to test the PCI bridge that is used to pass information between the control panel CPU and the PCH.

To Perform a PCH Tx/Rx Test

The PCH Tx/Rx test allows you to test the various serial communications ports on the control panel. This test helps to diagnose communication problems with external devices that you may be having on a particular serial communications port on the control panel.

A loopback adapter is required to be connected to the port you want to test.

Press HOME > More > Diagnostics > Panel Diagnostics > PCH Test > Tx/Rx Test.
Use the Com Port knob to select there serial port that you want to test.
- REMOTE X — test one of the remote ports.
- ExtLnk X — test one of the external link ports.
Use the Mode knob to select the transmission standard that you want to use to test the selected port.
- RS-422 — use the RS-244 (TIA/EIA-422) transmission standard.
- RS-422 Null — use the RS-422 (TIA/EIA-422) transmission standard configured for a null modem cable.
- RS-232 — use the RS-232 (TIA/EIA-232) transmission standard.
Press Test.

The outcome of the test is reported on the menu as passed or failed.
