General The LLD8021 is a Data Receiver and Video Transmitter.
The Data Receiver is used in Video Systems for low speed data communication interfaces over Fibre. It is compatible with LL232 which is a RS232 to fibre interface and the LL422 or LL8422 which is a RS422 or RS485 to fibre interface.
The Video Transmitter converts an composite video signal from a BNC connector to optical signal transmitted on fibre. When the video signal is present a led indicator will light up.
This unit are to be mounted on a Din Rail at the PTZ Camera.
This unit operates autonomously. Basic System Description The main purpose of this unit is to provide a cost effective fibre optic interface for PTZ Camera installations. (Pan Tilt Zoom)
The Data Receiver is used to control the camera. It converts the optical converted RS422 or RS232, one directional data, signal back to an electrical signal and transmits it on the copper lines. The Video Transmitter converts the composite video signal into an optical signal. Features - Repeat data without interference.
- Interface directly to the LL8023 Dual channel RS422 Transmitter and Video Receiver.
- Compatible with standard composite video.
Uses - Ideally suited for Pan tilt zoom systems in video applications.
Indications Data TX - Data Receiver on Fibre
Video RX - Video Transmitter on Fibre
