Output Monitoring
Note Output Monitoring applies only to standard Apex systems.
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 19 .
Figure 19. Example of Output Monitor Connection
For a standard Apex system, 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) 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 the
Planning and Installa-
tion Manual . Note that some pins on this connector are used for 110 Ohm
AES Reference cabling.
For example, in a
1
based system, to monitor Output #1 in a 256 x 256
system, route Source #1 to Output #257.
