2System Description
The Link L1500 HD wireless radio camera system comprises of three main components :-
Link HD Transmitter - L1500+L1510* Upconvertor
Link RF Down Converter (2 off) - L3070 (2/7GHz) or L3050 (3GHz)
Link HD Receiver - L2132/4
*Note- In this manual L1510 is used to denote any of the optional RF / UpConverter modules.
Optional components for camera control :-
Link Wireless CCU Interface - L1255
Link HD Camera Controller - L1520
For Camera manufacturers OCP, Grass Valley OCP400; Sony 700 Series, and Link Generic (Ikegami
HDK future)
The basic system will include 3dBi Omni vertically polarized antenna for the transmitter and down
converters; a range of alternative antennas can be supplied to meet different operational
requirements.
These will provide the basic operation of the Link HD system although other configurations are
possible including diversity operation, through Triax and fibre etc.
Please contact Link Research Ltd for details.
For basic operation, connections to the L1500 HD Transmitter unit are HD/SD video, analogue audio
and if required an RS232 data link. Power is supplied either via the attached battery plate or external
LEMO connector.
The power switch on the side of the L1500 is provided to switch the L1500 / L1520. This switch
cannot be used to control the supply to the forward camera interface plate which is always fed power
from the battery or external Lemo connector.

The L1500 can be supplied with various interface plates providing mounting of different batteries and
to different camera mounts - either IDX / Sony ‘V’ , PAG Loc or Anton Bauer Gold Mount are available.
Adaptor brackets are also available to allow mounting of the L1500 to the rear of Thompson LDK6000
series of cameras and the Sony 1500 series. These interface plates provide a ‘quick release’ to
remove the transmitter from the camera
A full list of accessories and cables is given at the end of this document
3L1500 Series Encoder/Transmitter
The L1500 Series Encoder/Transmitter is a compact HD/SD MPEG2 Encoder, DVB-T and LMS-T
modulator and 100mW output power amplifier (250mW FCC only). LMS-T is a unique robust
modulation scheme developed specifically for wireless camera use.
3.1 Operation
The L1500 is configured by the operator using the menu structure displayed on the colour LCD
display, 9 membrane push buttons are used to navigate through these menus and select the required
data. Please see 3.1.2 below for details of the L1500 menu structure.

The left / right and up / down buttons are used to select the required menu, or sub-menu the
Enter selects highlighted option which can then be modified with the up / down buttons.
Enter will then select the option or Cancel (‘X’) will exit back to the level above without selecting or
changing the settings..
Two Function keys are also available and can provide ‘short cuts’ into various functions without
navigating through the menu structure.
The ‘Status’ display can be used to display the battery voltage and current consumption of the
L1500 unit.
A single ’soft’ Power switch is also provided to control the L1500 unit. This switch must be pressed
for ~3secs to switch the L1500 on or off. This is to avoid accidental switching of the unit due to
knocking the power switch.
When power is applied to the L1500 it will revert to the condition when the power was removed.
E.g. If the L1500 was off when the power was removed; the power switch will need to be pressed to
turn the unit on. If the L1500 was on when the power was removed the unit will automatically power
on.

3.1.3 Transmitter Setup
It is important that when changing between modes of operation it is necessary to check and re-select
certain operating parameters due to interaction of some of these parameters.
For example when changing from DVB-T to LMS-T mode it will be necessary to reset the required
modulation scheme.
In the following examples the menus are described by :-- Level / Sub Menu / Function.
Some of the settings can be made from either the BASIC or the ADVANCED menus; the more
‘complex’ are only available from the BASIC level.
Following a ‘Restore Factory Defaults’ (Advance/System/Restore Defaults) it will be necessary to
select the required operating mode and modulation configuration as the factory defaults will not
currently give an operational setup and may result in ‘garbage’ characters on the display.
3.1.3.1 DVB-T Operation
The following sequence defines the changes and sequence required when changing to DVB-T
operation :-
Step Menu Sub Menu Option Setting
1 Advanced Modulation Modulation Type DVB-T
2 Advanced Modulation Guard Interval Must match

The selections greyed out are available in the transmitter , but not in the current version of the
receiver firmware. Check Support for updates.
These rates can be confirmed by checking the Advanced/Multiplexer/ Bit Rate menu.
It should be noted that this corresponds to the total data rate from the multiplexer which includes the
video, audio and any user data.

7 Advanced,Basic Modulation Power As Required
8 Advanced,Basic Modulation Frequency As Required

The encoder will set the data rate appropriately to match the modulation scheme settings.
The Table below defines the corresponding bit rates for LMS-T operation for both 10MHz and 20MHz
operation.

64QAM 2/3 27.6 45.2 29.2 58.5
Note 64 QAM not available on current software.
These rates can be confirmed by checking the Advanced/Multiplexer/Bit Rate menu.
It should be noted that this corresponds to the total data rate which includes the video, audio and any
user data.
Due to the improvement that LMS-T has over DVB-T these settings give approximately 50%
improvement of bit rates for the same level of ruggedness of the RF link.
For example DVB-T 16QAM, 1/32 GI, 1/2 CR gives 12Mbits whereas LMS-T 16QAM gives 18Mbits
3.1.3.3 ASI Operation
The L1500 can be used as an MPEG2 HD encoder providing an ASI output. The modulator and RF Up
converter are not required in this operating mode.
This provides ASI streams up to 90Mbits.
Step Menu Sub Menu Option Setting
1 Advanced Modulation Modulation Type ASI
2 Advanced Multiplexer ASI Bit Rate As Required
3 Advanced Video Encoder Bit Rate As Required
The encoder bit rate cannot be set above the Mux bit rate, if an attempt is made to exceed the mux
setting the encoder value will clamp to the highest allowed rate.
3.1.3.4 Remux Operation
The L1500 can be used to re-multiplex an additional service into the ASI data stream. This allows
two services can be transmitted on one RF Channel.
Step Menu Sub Menu Option Setting
1 Advanced Remux Enable On
It is important that the remultiplexed service multiplexer rate and the internal generated service
multiplexer data rate are within the available RF modulated data rate.

The main functions that require configuration at the receiver are :-
•Type of down converter and operating frequency
•Demodulation scheme in operation; DVB-T, LMS-T or ASI input
•Frame Lock
•Audio Output
Down Converter Type
The following sequence defines the changes and sequence required when selecting the required down
converter and receiver RF frequency :-

1 Unit DConv Type Select Type
2 Unit LNB Power On
3 Demodulator IPFreq As Required
4 Demodulator Guard Inv Match Transmitter
5 Demodulator Polarity Match Transmitter
The demodulator will then automatically detect code rate.
These received demodulation settings can be confirmed by checking the Demodulator menu.

4) None ( this will disable the Display TICK boxes)
Menu Option Setting

Decoder
The Decoder can be disabled , so that no error is displayed when only operating as a demodulator. It
can be operated in HD or SD mode. It can also be switched to decode an ASI stream either from an
external source via the rear panel ASI in socket, or be used to decode the ASI stream switched
internally from the demodulator.
Menu Option Setting
1 DECODER INPUT ASI in, Demodulator
2 DECODER MODE OFF, SD,HD
Note the decoder and the demodulator can be operated independently. Typically this can be used in
cellular diversity applications, where the demodulated ASI signal is taken via the ASI out connector, to
a Link Research Diversity Packet Switch L2014. The Packet diversity corrected output of the L2014
can then be fed back into the ASI in for decoding. Contac t Support for further information.
