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.
