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 Multiswitches have an Auxiliary DC Input which will power the Multiswitch 

as well as provide power to the SAT input and output Trunk Lines when fitted 

with a Whyte PSU.

A 12V DC switch is available to power a Mast Head Amplifier connected to the 

TERR input. If a Mast Amplifier is not being used this must be left in the OFF 

position.

SUBSCRIBER PORT MODE INDICATION

Each Subscriber Port has an LED indicator to confirm the mode status.

Legacy Mode: Solid Green

dSCR Mode: Blinking Green

Legacy Mode:

This  is  the  default  mode  of  the  Multiswitch.  In  this  mode  the  Multiswitch 

functions like a conventional legacy Multiswitch.

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 Multiswitch is NOT necessary to revert back to legacy mode.

STANDALONE MODE

Series D Multiswitches can be used in stand alone mode when powered directly 

Whyte

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

Multiple Whyte Series D Multiswitches can be connected in cascade using the 

supplied F Type Couplers. In Cascade Mode, the PSU can be connected to any 

Series  D  Multiswitch,  Splitter, Tap  or Amplifier within  the  system  for  ease  of 

installation. Hence, all Series D Multiswitches 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 consumption of all Multiswitches, Amplifiers and 

LNB's within the system. 

Always  terminate  the  SAT/TERR  Trunk  Outputs  of  the  last  Multiswitch  in  a 

cascade using 75Ω DC Blocked F-Type Terminators.

QUATTRO/WIDEBAND LNB SWITCH

The Series D range is compatible with both Quattro and Wideband LNB’s. To 

enable compatibility with a Quattro LNB (5 Wire Trunk) place the switch in the 

position  marked  “Q”.  To  enable  compatibility  with  a  Wideband  LNB  (3  Wire 

Trunk) place the switch in the position marked “WB”.

2 SAT RECEPTION

The reception of two satellites can be achieved via a 5 wire trunk by utilising 2 

Wideband LNB’s. The required satellite can then be selected by the STB using 

simple diseqc Satellite A and B commands.
