Individual Style Power Supply - RF Cable Installation
Signal connections for an arm mounted TV powered from an individual power supply requires a single coax cable no
longer than 300 feet, connected at the Set Top
Box’s “Output to TV” connection.
Some set top boxes also allow for the connection
of an external Antenna or other signal source via an “OFF-AIR IN”
connection. Please consult your set top box installation instructions for details.
NOTE: The drawing below is representative of the typical set top box. Your box may vary in appearance.
Central Style PDI -772HE Power Supply - RF Cable Installation
Low voltage AC TV power is present on each central power supply TV coax cable. A PDi Power Passer (part number
PD167-003) is required to route the AC power on the coax cable around any externally connected device such as the
Satellite Box. A Power Passer is required for each TV/STB connection. For new installations, the use of a PDI-772HE-
IND instead of PDI-772-HE will eliminate the need for the power passers.
NOTE: The PD167-003 Power Passer is an optional device NOT supplied with the interface module and is
only required for centrally powered arm mounted televisions. Please contact your PDi distributor to order this
device.
1. Remove power from the TV at the central
power supply.
2. Connect a coaxial cable from the STB
“OUT TO TV” to the Power Passer’s “RF
IN FROM EXTERNAL DEVICE”.
3. Locate the coaxial cable from the central
power supply. Connect this cable to
“FROM POWER SUPPLY”.
4. Connect the coaxial cable from the TV to
“COMBINED SIGNAL TO TV.” The TV
coax should be limited to 150’ to
accommodate the central power supply
coax length limitations.
5. Connect an Optional Secondary RF signal
coaxial cable from the Power Passer’s
“RF OUT TO EXTERNAL DEVICE” to the
Set Top
Box “OFF-AIR IN”. This
connection is only necessary if you wish
to view TV signals that are already
present on your system in addition to Set
Top Box signals.
