PROception proLINK22 Instructions For Installation And Use

Technical data
RF input and output
RF loop-through 87.5 – 790 MHz, gain 0–3 dB to each output
Modulator output channel E21 – E60, set via Sky menu
Modulation UK System I (DSB), level approx. 70 dBμV at each output
AV and power interface Sky I/O port via 0.5 m flying lead
Remote control – see note below
IR 'eye' current available (9 V) 10 mA max via each output, s/c protected
(no external PSU) total current must not exceed 15 mA
System load with external 12 V PSU 75 mA max. via RF - OUT 2 only, s/c protected
Connectors and standards
RF-IN 'IEC' (female) (IEC 61169-2)
RF-OUT Type-F (female) (IEC 61169-24)
Sky I/O 10-pin mini-DIN (proprietary interface)
Operating temperature rang 0 – +40 °C
External DC power 2.1/5.5 mm DC jack (centre pin +ve)
EMC standards BS EN 55013 & BS EN 55020
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.

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
OFF or not
Green ON
installed
Orange ON ON
Red OFF ON

Status
Normal condition for system with no
external power unit.
Normal condition for system with

Sky box powered down or booting up.
Invalid or fault condition if persistent.
