Output Monitoring
Setting the Output Monitor Address
The Monitor rotary switch on the back panel is used to set the control
address for the available monitor outputs. For example, with a 128 x 128
Routing switcher equipped with redundant NR-33000 boards, the quality
control monitor could be connected to output monitor connector 1 and the
monitor switch set to 128; the control system would then select Output 129
*For Jupiter-controlled (0-based) systems, subtract one (1) from these numbers.
*
for monitoring purposes. See Table 40 .
The 512x1024 Routing switcher does not use the “512” Monitor position.
Figure 117. Output Monitor Address Switches
Note Some units in the field may have incorrect labels on these switches. The
labels shown in
Figure 117 are correct. On all the rotary switches, use the tri-
angular arrowhead for pointing and selection (not the screwdriver slot).
If the router has been output-expanded, then each Monitor switch would
be set to the highest output number for the system. For example, if a TRX-
NXT-256x256 has been output-expanded to 128 x 256, the Monitor switch
would be set to 256 on both frames.
The second BNC connector of each pair provides an inverted output signal.
Note For Jupiter-controlled (0-based) systems, subtract one (1) from these
numbers in the following tables.
