X-Net Star Driver Module
The X-Net Star Driver module provides 8 buffered data ports for connecting multiple telemetry devices over a single data transmission channel.
The X-Net Star Driver is a companion card to the X-Net range of optical and codec modules. With the X-Net Star Driver, it is possible to connect up to 8 telemetry devices over a single X-Net data channel whilst maintaining a star wiring topology.
Therefore, the star driver is ideally suited when a star format network or large cable runs are required. Additionally, the unit also enables networks to be split into segments with different data protocols on each star driver. Each Star Driver is also independently configurable to support different data formats as required. Thus allowing for cost effective system expansion of the CCTV network without the need to re-route data cabling.
Features & Benefits
Add 8 buffered data ports - Flexibility to add new devices to the CCTV network without having to replace existing modules
Configurable data formats - Each Star Driver can be configured to support RS232/RS422/RS485 2 wire or 4 wire configuration.
Possible to Daisy Chain multiple cards - In case more data channels are required, it is possible to Daisy Chain multiple Star Driver cards together
Compatibility - The X-Net Star Driver can operate as a companion card to any X-Net module. It synthesizes up to 8 star wired telemetry devices (typically dome or PTZ cameras) to a single data channel ready for onward transmission over a network
