Master VDA38
You may connect up to 8 more VDA38s to the outputs of a
master
VDA38, for a total
of 64 TV outlets. The longest recommended coax run should not exceed 150’. That
is a total of the coax from
master
to
slave
and
slave
to TV.
Slave VDA38s
Expanding the VDA38:
Typical Installation:
Each VDA38 must be powered individually. Each
slave
VDA38 can have local
modulators and a zoned IR system for TVs connected to the eight outputs. Any
modulator signals injected into a
slave VDA38
will be viewable only on the eight
TVs connected to it. Modulators connected to the
master
VDA38 will be viewable
on all TV outputs including
slave
VDA38s.
Circuit Breaker:
6
The VDA38 has a built-in circuit breaker. If the power LED is not lit, reset the circuit
breaker by disconnecting and reconnecting the power supply. If the system does
not reset, look for an installation error.

Note:
Connecting a 75ohm
terminator directly to an
output of a VDA38 will
cause the circuit breaker to
trip.
The VDA38 works like a zero-loss splitter. The signals you put on the
antenna/CATV input will appear on the outputs with about 3dB of gain.
