SAFETY
The Mulswitches are intended for indoor use only.
Do not install the Mulswitch in damp, humid, hot or dusty areas.
Switch o and remove the power supply when making connecons to the
Mulswitch to avoid damaging the unit.
Always earth bond the Mulswitch using the Earth Bonding Lug and/or the
Earth Terminal Bars to a suitable earth bonding point using minimum 4mm²
diameter earth cable.
PRECAUTIONS
To ensure trouble free operaon:
Do not remove the cover of the Mulswitch or disassemble it as this will
invalidate the guarantee.
The female F connectors on this unit were designed for use with '100' type
coaxial cable with a centre core diameter of 1mm². When using larger CT125
or CT167 cables, you must ensure that suitable F connectors with reducing
pins are used otherwise damage to the unit will occur which will invalidate the
guarantee.
Do not over ghten the F connectors (nger ght only).
GUARANTEE

purchase against defects. Within this guarantee period, Whyte Technologies
will repair or replace the faulty product. In the unlikely event, please return
any faulty products to your dealer.
The Guarantee will be deemed as void if the serial number on the product

GENERAL DESCRIPTION
Whyte Series D is a range of advanced Cascadable Hybrid dSCR Mulswitches.
Seamless integraon with convenonal IRS Systems due to extremely low
power consumpon, low loss passive trunks and high gain TERR, make the
new Series D range from Whyte the most versale and easy to install dSCR
Mulswitch range available.
The Series D range can be directly conjoined with Series 5 convenonal
Mulswitches using the supplied F type couplers to seamlessly create Hybrid
IRS Systems.
Use Series 5 Launch Ampliers, Taps, Spliers and Power Supply Units to
create large scale dSCR only or Hybrid IRS Systems.
Each Subscriber Output provides Satellite (SkyQ, dSCR & Legacy), TV and
Radio. Satellite subscriber signal levels in both Legacy and dSCR mode are
automacally set to 89dBμV (self-commissioning/AGC). dSCR and Legacy
mode is automacally detected and switched over on a per-subscriber port
basis.
Terrestrial signal levels are controlled via a manual Gain Control knob and a
selectable Protean Tap which permits a wide range of TERR input signal levels
ranging from 50 to 108dBμV.
The recepon of 2 satellites can easily be achieved by ulising 2 Wideband
LNB’s and switching the unit to Wideband LNB mode.
The unit can be powered directly via the DC input port or be remotely powered
via the trunk lines.

TECHNICAL DESCRIPTION
DC POWERING
The Whyte Series D range can be Line Powered via any of the SAT input
and output Trunk Lines. All SAT Trunk Lines are DC passing, whilst the TERR
Trunk Line is DC isolated.
The Mulswitches have an Auxiliary DC Input which will power the Mulswitch
as well as provide power to the SAT input and output Trunk Lines when ed
with a Whyte PSU.
A 12V DC switch is available to power a Mast Head Amplier connected to
the TERR input. If a Mast Amplier is not being used this must be le in the
OFF posion.
SUBSCRIBER PORT MODE INDICATION
Each Subscriber Port has an LED indicator to conrm the mode status.
Legacy Mode: Solid Green dSCR Mode: Blinking Green
Legacy Mode:
This is the default mode of the Mulswitch. In this mode the Mulswitch
funcons like a convenonal legacy Mulswitch.
dSCR Mode:
When a dSCR Set Top Box is connected, the corresponding port will
acknowledge the dSCR DiSEqC commands and switch to dSCR mode. To
revert back to legacy mode the power to the Subscriber Port needs to be
interrupted momentarily. A reboot of the Mulswitch is NOT necessary to
revert back to legacy mode.

STANDALONE MODE
Series D Mulswitches can be used in stand alone mode when powered
directly via the 18V Auxiliary Input by using a Whyte Power Supply Unit (sold
separately).
Any unused (open) SAT/TERR Trunk Outputs must be terminated using 75Ω
DC Blocked F-Type Terminators.
CASCADE MODE
Mulple Whyte Series D Mulswitches can be connected in cascade using the
supplied F Type Couplers. In Cascade Mode, the PSU can be connected to
any Series D Mulswitch, Splier, Tap or Amplier within the system for ease
of installaon. Hence, all Series D Mulswitches will be remotely powered via
the SAT Trunk Lines.
Care must be taken to select the appropriate type and number of PSU's
required depending on the current requirements of the system as a whole.
Remember to calculate the total current consumpon of all Mulswitches,
Ampliers and LNB's within the system.
Always terminate the SAT/TERR Trunk Outputs of the last Mulswitch in a
cascade using 75Ω DC Blocked F-Type Terminators.
QUATTRO/WIDEBAND LNB SWITCH
The Series D range is compable with both Quaro and Wideband LNB’s.
To enable compability with a Quaro LNB (5 Wire Trunk) place the switch
in the posion marked “Q”. To enable compability with a Wideband LNB (3
Wire Trunk) place the switch in the posion marked “WB”. Note: when using
wideband mode ensure that any ampliers, taps or spliers that form part of
a system are wideband compable.
2 SAT RECEPTION
The recepon of two satellites can be achieved via a 5 wire trunk by ulising
2 Wideband LNB’s. The required satellite can then be selected by the STB
using simple diseqc Satellite A and B commands.

INSTALLATION INSTRUCTIONS
MOUNTING THE MULTISWITCH
Select a suitable locaon to install the Mulswitch. Do not install the
Mulswitch in damp, humid, hot or dusty areas. Using the screw slots on the
Corner Brackets, secure the Mulswitch using the appropriate xing screws
and wall plugs to suit the relevant wall surface or cabinet.
CONNECTING THE SAT & TERR INPUT AND OUTPUT TRUNK CABLES
Use a suitably sized Satellite Dish to provide adequate signal levels from the
satellite being received. Ensure that the Satellite Drop Cables are connected
correctly to the LNB's. Ensure that the F Connectors are properly sealed
against water ingress. If a Composite Cable (mul core coaxial cable) has been
used, ensure that the outer jacket is not facing upwards and cannot collect
rain water.
Check the Terrestrial Drop Cable and ensure that this has also been sealed
against water ingress. If a Triplexer has been used to combine FM and DAB
aerials with the UHF Terrestrial Aerial, ensure that this is also water ght.
Ensure that all drop cables have drip loops prior to their entering the building.
Connect the SAT and TERR drop cables to the corresponding Satellite and
TERR Inputs on the Mulswitch. Connect any addional Mulswitches or
Trunk Cables to the Satellite & TERR Trunk Outputs as applies. Ensure that
you terminate the last Mulswitch in a cascade using 75Ω DC Blocked F-type
Terminators.

EARTH BONDING
Earth bond the Mulswitch to the Earth Bonding Lug and/or the Earth
Terminal Bars using minimum 4mm² Earth Bonding Cable. It is best pracse
to earth bond across all Mulswitches using a single unbroken Earth Bonding
Wire. To achieve this, strip away 3cm of the insulaon of a length of 4mm²
Earth Bonding Wire. See Figure 1.
Unscrew the Earth Bolt on the Earth Terminal Bar to provide enough clearance
to wrap the Earth Bonding Wire around the Earth Bolt. See Figure 2.
Tighten the Earth Bolt and route the Earth Bonding Wire to all other Earth
Terminal Bars and terminate as detailed above. Make sure that the Earth
Bonding Cable is connected directly to the building’s PME.

CONNECTING THE POWER SUPPLY UNIT (PSU)
Calculate the total current consumpon of the Mulswitch(es), LNB and
any Launch Ampliers that make up the complete IRS System. The current
consumpon of the Series D Mulswitch range can be found in the Specicaon
secon of this manual. If in doubt, assume the current consumpon of each
LNB to be 200mA max (0.2A). Connect a suitable Whyte PSU to the Auxiliary
18V DC Input. If more than one PSU is required, the addional PSU(s) may be
connected to any other Mulswitch, Launch Amplier, Tap or Splier within
the system. When all connecons have been made, connect the PSU to a
240V supply to power up the IRS System. It is highly advisable to isolate and
hence divide the system in to DC Groups containing only a single PSU per
group, by using F-type DC blockers (not supplied).
CONNECTING THE SUBSCRIBER CABLES
Terminate the Subscriber Cables with good quality F Connectors and connect
to the Subscriber Outputs. The F Connectors should be ed to the coaxial
cable correctly, ensuring that the centre core protrudes 3mm above the F
Connector body. See gure 3. Ensure that you do not exceed the bending
radius of the Coaxial Cable being used.
