General The LLD8021 is a Single Channel DIN Rail-mountable Data Receiver and Video Transmitter. Two LLD8021's can be connected via optical fibre to a single LL8023 rack-mount card - which is a two channel Data Transmitter and Video Receiver.
The Data Receiver is used in Video Telemetry Systems, for low speed RS422 data communication over fibre to PTZ cameras. It is also compatible with the LL232, which is an RS232 to fibre interface; with the LL422 or LL8422, which is an RS422 or RS485 to fibre interface; and with the LL8023 two channel data transmitter and video receiver card.
The Video Transmitter converts a composite video signal, received on a BNC connector, to an optical signal that is transmitted onto fibre. When the video signal is present, an led indicator will light up. It is compatible with LL803R three channel video receiver card. The unit can be mounted on a DIN Rail at the PTZ Camera in the field. Basic System Description The main purpose of this unit is to provide a cost effective fibre optic interface for PTZ (Pan Tilt Zoom) camera installations. It basically receives PTZ information for the camera, and transmits the video signal from the camera. Features - Repeat data without interference
- Interface directly to LL8023 Dual Channel Data Transmitter and Video Receiver.
- Compatible with standard composite video.
Uses - Ideally suited for Pan Tilt Zoom camera systems in video applications.
Indications Data - Data Received from the fibre
Video - Video Signal Transmitted onto the fibre
Power - Unit is Powered
