Digital Optical coupler
The CA 4211 digital opto-coupler is used to convert the NetRateBus signals on two optical fibres for distances of up to 2000 metres to combine two buildings or for large buildings with central control room and distant conference rooms. The CA 4211 is connected between the MCS-D 200 control unit and the CA 4146 power supply unit or between the MCS-D 200 control unit and microphone units when using the external DC voltage input. The CA 4211 is powered via the 6-pin system cable or the separate DC connection. The CA 4211 can only be used in pairs with a crossed connection of the Tx and Rx connectors.
