EXPO204 RS485 Serial Data Distributor - 2 x Master / 4 x Slave

For systems with multiple PTZ cameras and controllers, serial data control through DVR’s or encoders and for ancillary equipment such as video switching matrices, Serial Data Distributors help to simplify the installation by providing a central point to connect data lines, whilst balancing the control signals, filtering out noise, preventing dropped data packets or over-runs and broadcasting commands across an RS485 network.

The IRIS-EXP0204 is a small form-factor module with two RS485 data inputs (controllers, CMAC etc), four RS485 data outputs (Cameras).

Any device that controls camera movement, or switches a video matrix is regarded as a controller. RS485 data from control devices connects to an input.

The IRIS-EXP0204 operates from a 12VDC and draws very low power. Data lines connect into the unit by means of screw terminal connectors (2 wire RS485).

Not only can the IRIS-EXP0204 be used to drive up to four slaves (cameras, matrices etc) from up to 2 control devices but it can also be used to provide extra inputs for larger scale systems by ‘daisy chaining’ a data line from an output into another serial data distributor.
