Multiple UA840 Setup (Figure 9)
1.
Connect the CASCADE ports (port 5) for RF OUTPUT
Channels A and B of one UA840 to the ANTENNA IN-
PUT, channels A and B, of a second UA840.
2.
If desired, connect additional units in the same man-
ner.
3.
To daisy-chain units together with Power OUTPUT
cables, connect the Power OUTPUT port of the UA840
to the Power INPUT port of one receiver. Connect the
remaining receivers similarly. Connect the POWER
INPUT of the unit to a power supply.
WARNING: When adding additional UA840’s to a sys-
tem, each UA840 should be connected to a separate
power supply. No more than five (5) receivers can be
powered from a single UA840. Daisy-chaining multiple
UA840’s through the Power OUTPUT ports will overload
a single power supply, possibly causing damage to the
equipment.
