Note: Maximum eye current loading on RF outputs (without external PSU)
■ Using PROception proSAT1EYE (Mk 2 or later) a maximum of three eyes may be connected, two
via a splitter on one output and one directly connected on the other.
■ Using other makes of eye (where current loading may exceed 7.5 mA) only one eye is
permitted.
■ Exceeding these limits will overload the internal DC-DC voltage converter and may damage the
unit.

proLINK22
UHF Modulator
For use with Sky Satellite Receivers
INSTRUCTIONS FOR INSTALLATION AND USE
The proLINK22 is a versatile UHF analogue modulator intended for use with newer Sky
set-top receivers without RF outputs (e.g. DRX595). This unit connects to the I/O port on
the Sky receiver and replaces the RF distribution and remote control functions previously
available from the RF - OUT 1 and RF - OUT 2 connectors.
Additional features
■ RF loop-through for Freeview, etc., replaces Sky ANT - IN connector.
■ Modulator output coverage: RF channels 21 – 60. Simple RF channel setting using
the Sky box Setup menu.
■ Remote control capability on both RF outputs – supports up to two remote outlets
with IR ‘eyes’, (where no local RF output is required).
■ A third output location can be supported by using a splitter (see text).
■ External power supply option allows construction of larger systems.
■ 3-colour power status LED.
Location
The modulator can be located in any convenient position close to the Sky receiver box
and does not require fixing. Clearance of at least 25 mm should be allowed around the
front and sides of unit for ventilation. Avoid positioning the modulator on top of a stack
of other equipment as this may result in overheating. The fixing lugs may be used if
desired to secure the unit to a cabinet etc. (screws not supplied).
Power supply and indicator
The modulator is powered from the associated Sky receiver via the I/O link cable. No
separate power supply unit is required unless a larger distribution system (usually 4 or
more output locations) is to be installed.
For larger systems, where a line-powered distribution amplifier such as the proAMP104X
or proMHD14R is used, an external proPSA123 or proPSA125 power unit must be
connected to the modulator. If a locally powered distribution amplifier is used (proAMP-R
series or proAMP310X with local PSU) the modulator will not require a separate power
unit.
The power status LED on the front of the unit works as follows:
LED colour Sky box power External PSU Status
Green ON
OFF or not
installed
Normal condition for system with no
external power unit.
Orange ON ON
Normal condition for system with
external power unit.
Red OFF ON
Sky box powered down or booting up.
Invalid or fault condition if persistent.

Output connections and control ‘eyes’
The proLINK22 has two RF outputs each of which can be connected directly to a TV
receiver or connected via an infrared receiver ‘eye’ to provide remote control of the Sky
box. These outputs work as follows:
■ When no external power unit is connected, the two RF outputs are interchangeable.
■ However when an external power unit is used RF-OUT 2 must be used to feed the
distribution amplifier. RF-OUT 1 can then be used if desired to feed an additional TV.
■ Each output may be split 2-ways (use 2-way splitter type proSPL204), provided that
the eye current limits are observed – see table and note on Page 4.
RF Channel setting and remote receiver tuning
To set the desired modulator output channel use the Setup menu of the Sky box, and
choose the RF Outlets option. The Setup menu (normally hidden) is accessed by entering
SERVICES, 0, 0, 1, SELECT on the Sky handset. (Note that the RF outlet power option in
this menu has no effect for the proLINK22.)
Choose an output channel in the range 21–60 which does not coincide with any off-air
DTT multiplex in the area. See http://www.digitaluk.co.uk/coveragechecker/ (select the
detailed view box) to find the local broadcast channels.
With the Sky box switched on, tune all connected remote TVs to the chosen analogue RF
channel. Refer to the instructions for particular TV models if necessary.
Application examples
■ Fig. 1 shows a basic 1+2-way system with two remote TVs. Either of the RF outputs
could alternatively be used to provide an RF feed to the main TV if necessary (making
a 1+1-way system).
■ Fig 2 shows a 1+4-way system using a proAMP104X (or proMHD14R) amplifier.
■ Fig 3 shows a 1+10-way system using a proAMP310X amplifier. In this system the
power unit must be connected to the amplifier, not the modulator. (Alternatively a
proPSU112X may be used in-line between the proAMP310X and the proLINK22.)
