2.2.  DESCRIPTION

Fibre Optic ADA-7040 is a device used to connect units with RS485/RS422 interface without interfering with the data format. The use

of fibre-optic provides complete isolation between connected devices and resistance to interference on the transmission bus. The fibre

connection is implemented by a line consisting of two fibres - one fiber for the TX signal and one for RX signal. Using two this type

converters, can be use for communication with devices quite distant from each other eg. Computers, controllers etc. 

ADA-7040 is equipped with screw terminal block for RS485/422 and power connections. The converter supports data rates of up to

2Mbps by four or two pairs of twisted pair connected to the screw terminals. The device use to operate lines RX +, RX-, TX +, TX-.

To   RS485/422   bus   built   on   the   ADA-7040   can   be   connected   32   devices   operating   in   half   duplex   mode   or   full   duplex   mode.

Overvoltage protection was made on base safety diodes and fuses on each RS485/RS422 lines.
