1. System Description

The Link L1500 HD wireless radio camera system comprises of three main components :-

Link HD Transmitter - L1500+L1510* RF module

Link RF Down Converter (2 off) - L3025 (2GHz)

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 a full list of supported camera manufacturers models go t our website

http://www.vislinknews.com/services-customer-support-supported-cameras.htm

Manufacturers include Ikegami, Sony, Thomson, Panasonic and Hitachi.

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

2. L1500 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.

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 bbelow for details of the L1500 menu structure.

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.

The ‘RF’ function key is used to toggle the RF output on / off without the need to enter the sub

menus.

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

nocking the power switch.k

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.
