4INTRODUCTION
The Lynx Receiver range are highly flexible, high performance products based on compact DVB-T and LMS-T
demodulators using VISLINK’s Maximum Ratio Combining diversity algorithm, and a combined HD/SD
decoder.
The ultra low delay MPEG2 SD/HD Decoder has been speed optimised to operate with the Link Research Ltd
family of MPEG2 Encoders, which utilise field encoding. This range of decoders will not support frame
decoding. A licensable upgrade will allow support for B-Frame or ‘Generic’ MPEG2 Decoding that will support
frame decoding, but at higher delay.
The Decoder can also be licensed to support H.264 decoding. This will be available in different levels from
Main Profile 4:2:0 8 bit, up to High Profile 4:2:2 10 bit.
The product range is based on three hardware variants: Demodulator-only (L2074), Decoder-only (L2170) and
Demodulator-Decoder (L2174). All other variants are licensable and therefore allow for field upgrades by
changing the license to enable extra features as required. Please contact VISLINK for details.
This document has been written primarily for the complete L2174 Receiver. Where there are major differences for the L2170 and
L2074 variants they will be indicated, however some minor differences may not always be documented.
4.1 L2174 Internal Architecture
The L2174 is based on 3 main hardware components: Demodulator card, Decoder board and Controller board.
The L2074 & L2170 products do not have the Decoder and Demodulator boards fitted (respectively). Please
note that upgrading one of these to a full L2174 requires the unit to be returned to VISLINK.
As shown in the block diagram above, the Demodulator board generates an ASI stream from the RF inputs
and/or the external ASI, then passes this to the Decoder board to generate the Video and Audio outputs. In
addition, the Decoder extracts embedded (or ’wayside’) RS232 data if it is present in the transmission, as well as
return data from a VISLINK Camera Control System. There are 2 ASI connections between the boards to
allow extra flexibility in how the unit is configured (see later).

This displays, at a glance, the current frequency selection and modulation parameters. The top line also displays
the lock status of the individual RF and ASI inputs ( 9= locked ), and the video format detected by the
decoder. The bottom line displays the currently selected Decoder and Demodulator Modes.

Pressing the MENU key will take the operator to the main setup menus; pressing MENU again at any point
returns to this display.
If any parameter has not yet been initialised (e.g. shortly after power-up), then it will display as dashes (“---“).
The L2074 Main display is identical, except the Video Format is not displayed.
The L2170 Main display shows the Service selection menu (see section 9.2.1), plus the ASI lock status and
Video Format.
9.1 Demodulator Menus (L2174, L2074)
9.1.1 Input Mode
Allows the operator to select the required Modulation scheme being used (DVB-T, LMS-T).
When the unit is first switched on, and when switching modulation modes, the unit performs a self
test routine on the RF front end. This causes a slight delay (15-30s) before the demodulator will lock.
For more details see section 10.2
Individual inputs can be turned on and off as required. Note that in 20MHz LMS-T mode, only Inputs
1 & 2 are active.
The Receiver supports the Link Remote Triax System (L1273/4), which allows downconverters to be
sited remotely (up to 1km from the receiver). This can be set to Single or Dual mode; in Single mode,
2 downconverters are mounted remotely, and the triax system is connected to RF1 and RF2 on the
Receiver. The other 2 inputs can be connected directly to downconverters. In Dual mode, two triax
systems are connected, to RF 1/2 and RF3/4 respectively. This feature defaults to Off.
9.1.2 Demodulator Setup
Operator can configure Frequency, Bandwidth, Guard Interval and Polarity. Apart from Frequency, all
have ‘Auto’ modes, which allows the Demodulator to detect the correct configuration from the
received signal.
If a frequency is entered that is outside the range of the currently selected downconverter, then an
‘Invalid Frequency’ alarm will occur, and reception will not be possible,
9.1.3 Downconverters
For each RF input, select the downconverter type, and turn on power to the downconverter. All
current Vislink downconverters are listed, or the Local Oscillator (LO) frequency of any unlisted
downconverter may be entered by selecting OTHER. To enter the incoming UHF frequency directly,
select NONE. When NONE is selected, downconverter power is disabled.
To change all RF inputs to the same downconverter settings at the same time, SET ALL INPUTS
should be set to ON; to set them individually, turn this setting OFF.
Example Home screen
(when locked)
All manuals and user guides at all-guides.com
all-guides.com

Document: CL140072 L2174 Manual Issue 2.0 Page 17 of 26
Note that the Receiver frequency will not change according to the downconverter type, unlike
previous Link products. This greatly simplifies setting up the unit to work with multiple
downconverter types, and also when switching between downconverters that cover the required
frequency range.
9.1.4 Deinterleaving
The Lynx Receiver has a licensable deinterleaving option, to match the interleaving option in the
L1500 transmitter. This option adds an extra layer of error correction to the ASI data steam that allows
long breaks in RF reception to be corrected. In the transmitter, the user can select the amount of FEC
used and the duration of RF break that can be corrected. When Enabled, the Receiver automatically
detects these settings and adjusts the deinterleaving appropriately. The settings are displayed for
information but cannot be altered. Adding interleaving to an ASI stream reduces the ASI bit rate
available for video/audio etc. and adds a delay to the signal. The additional delay is shown in the
menu. For more details see section 10.5.
9.2 Decoder Menus (L2174, L2170)
9.2.1 Services
Number of Services: Displays the number of services in a particular incoming multiplex.
SERVICE: In Auto mode, displays the currently selected service. In Manual mode, allows the
decoded service to be selected as follows:
Press ENTER on this menu item followed by UP/ DOWN arrow keys; the
service “NAME” of each service available in the incoming multiplex will be
displayed on the line below. When the desired service is shown press ENTER.
This will then be decoded in to video / audio outputs provided the signal is of the
correct format (SD/HD), and is not scrambled or a valid descrambling key has
been entered.
Once selected, this service name will become the “preferred” (or Default) service,
such that on power / signal interruption this particular service will be the only one
that is decoded, on restoration of power / signal. If the preferred service name
appears in a particular multiplex, this is the one that will be decoded unless another
is chosen.
If the Default service name is not present then no service will be decoded. NB
This means that if the service name is altered in the encoder, then decoding will
stop.
If a service has not been given a name (some encoders default to this mode), then
the decoder will create a name of the format “Prog00001”, which will allow it to
be selected.
Auto: When ON will always select the first service in the multiplex. Once a service has
been selected in this way, it will remain selected even if other services are added to
the multiplex. Auto mode defaults to ON.
Default: Displays the current Default service name. It is only valid, and can only be edited,
when Auto Mode is Off.
9.2.2 Video Output
Output 1/2: Select the output mode of the two rear panel connectors. In HD mode this is fixed
to SDI; for SD it can be switched between SDI and CV (Composite Video).
In both modes a Status overlay can be added to the video output which gives an
at-a-glance update on the status of the link.
Overlay Type: This is only displayed if the overlay is turned on. There are 2 types, Basic and
Service. In Basic mode, the following information is displayed: Frequency, Guard
Interval, Mode, Constellation, FEC, Camera Volts (when used with a Link L1500
Wireless Camera Transmitter). In Service mode, just the selected service name and
the Camera Volts are displayed. In both modes there is also a bar across the screen
that represents the MER from the best RF input.
All manuals and user guides at all-guides.com

Document: CL140072 L2174 Manual Issue 2.0 Page 18 of 26
Background: This is only displayed if the overlay is turned on. This allows the opacity of
background of the overlay to be varied from Off (transparent) to 100% (opaque).
Default Std: This selects the format of the output video when no video is present on power-on.
If video lock is subsequently achieved and then lost, the format of the locked
video is used.
NTSC Ped: Selects whether Pedestal is inserted on the NTSC output (SD only).
PsF Mode: Tells the decoder whether to interpret the incoming video as segmented frame or
interlaced video (HD only).
9.2.3 Audio Output
Audio A/B: Selects the output format on the rear panel: Analogue or AES digital (output on
Right channel only). Also displays status information from the decoded audio.
9.2.4 Decoder Config
9.2.4.1 Decoder Options
Video Mode: Select between the available Decoding modes
Video Loss: Select behaviour on loss of video – display blue screen or freeze display
Frame Lock: Select between SD Black&Burst and HD tri-level sync (HD mode only) on the rear
panel input, or disable this function.
Pixel Offset: If Frame Lock enabled, enter the offset required in pixels.
9.2.4.2 Descrambling
Select Descrambling mode (if licensed) and enter key(s)
9.2.4.3 RS232 Data
Enable extraction of embedded data from the MPEG stream. Displays the detected baud rate and
parity. Displays dashes if no data detected.
9.2.4.4 Identifiers
Audio DIDs: Selects into which SDI Group the two Audio channels will be embedded.
PIDs: The PIDs detected in the currently selected service are displayed.
9.3 Stream Management Menu
These menus control aspects of the transport stream handling in the unit not directly related to the
Demodulator or Decoder.
9.3.1 Routing
DIVERSITY: When enabled, packet diversity is performed between the output of the Demodulator
and the external ASI input.
SOURCE: Select the source of the Transport Stream used for each of the 3 outputs (Decoder, ASI
and IP). If Diversity is enabled, then DEMODULATOR is replaced by DIVERSITY in
each list of options.
9.4 System Menu
9.4.1 Presets
Up to 16 preset configurations can be saved in the unit.
Save To Memory: Specify the number of the preset to be saved. It is possible to enter a name
for the preset if desired. Change SAVE to YES and press ENTER to save
the preset.
Recall From Memory: Specify the number of the preset to recall; if a name has been assigned this
will be displayed. Change RECALL to YES and press ENTER to load the
preset.
All manuals and user guides at all-guides.com

Document: CL140072 L2174 Manual Issue 2.0 Page 19 of 26
Defaults: To restore the unit to factory defaults, change RESTORE DEFAULTS to
YES and press ENTER.
NB. Performing a Restore Defaults will clear all stored Presets
9.4.2 Diagnostics
Detailed information on the performance of the unit can be displayed by function:
Demodulator: pre- & post-Viterbi errors; TPS & FEC Lock, Downconverter currents & SELF
TEST results.
Decoder: Video Lock, TS lock, Frame Lock, Chroma & GOP formats. In h.264 and Generic
MPEG2 modes, also displays picture format information
Unit: Temperatures
System: Camera volts (when used with a Link L1500 wireless camera transmitter)
9.4.3 Control Interfaces
Configure external control interfaces:
Web Identifier: Set a text string to be displayed on the unit’s web page. This helps to identify which
unit is being controlled when working with multiple units.
Ethernet port: Set the IP parameters for the Ethernet control port. NB This is not related to the
Video IP port (see section 1.1).
Status pin: The Status pin in the CC/ALM connector (see section 6.9) is an open-drain output
that connects to Ground when active. By default this is when an Alarm occurs; it is possible to select
whether it is active high or low. It can also be driven manually using this menu, however.
9.4.4 Service
9.4.4.1 HELP
These menus display information useful when contacting Vislink Service, in particular the versions
of the various modules in the unit. There is also an option to dump the unit’s current configuration
to a USB memory stick. This file (configuration.txt) can be emailed to customer support in order to
assist with any problems.
