The following examples are based on the video signal paths shown in Figure 15 and a
VS-6464DN-EM device installed as follows:
•
64 inputs and 64 outputs.
•
The test module is configured (see Installing the Test Module on page 45 ).
•
65 configured inputs and 65 configured outputs (see Configuring the Number of Installed
Input and Output Ports on page 32 ).
