D-type telemetry external loopback connectors
These self-test external loopback tests confirm that the D-type telemetry ports are
working correctly. To conduct this test, you need to link the D-type ports for
cameras 1–16 to the ports for cameras 17–32. You do this by linking the two
removable screw terminal blocks with pairs of link wires, as shown below for the
first block of four cameras. (This pattern should be repeated for the remaining three
blocks.)

Video routing
VisiPC includes a powerful test to automatically check the routing of video signals
from all the camera inputs to all the monitor outputs, including the expansion
connection between units.
Before running this test, you should connect all available sources of clean video to
the camera inputs. This test is therefore best conducted once installation is
complete.
To run the test:
1.
Select the VisiPC Self-Test Tab.
2.
Select the Test Type to Video Routing from the Run Tests button.
3.
Press the Send button.
