Output Monitoring
Output Monitoring
Note Output monitoring is a standard Apex system feature.
Output monitoring allows verification of switcher performance without
interrupting normal operations. A separate internal switching system is
used to switch the selected output signal to the Output Monitor connector.
See
Figure 42 .
Figure 42. Example of Output Monitor Connection
Using a standard system control panel, the operator picks an output as
usual—in this case, the Output Monitor. (The physical number of the
Output Monitor connector is determined by the Max Size switch setting
plus 1—see Max Size Switch
on page 102 .) The operator then selects an input,
but this input is actually one of the switcher outputs.
Two connector sets are provided on each chassis: OP MON A, which corre-
sponds to the A Matrix board; and OP MON B, which corresponds to the
optional B (secondary) Matrix board. Within each set are two connectors: a
BNC type for 75 Ohm cabling, and a 9-pin D female type for 110 Ohm
cabling. Pinouts for the D connector are shown in
Figure 36 on page 89 .
Note that some pins on this connector are used for 110 Ohm AES Reference
cabling. The signal selected by the control system for monitoring is always
present on both the BNC and the D connectors.
