At present, lots of important equipment still uses RS-232 interface design. But RS-232 is a point to pointinterface, which limits the transmission distance between equipment andcomputer to 15m. To overcome the limitation, many users adopt the RS-232 to RS-422/485converter and connect RS-232 equipment to industrial RS-422 or RS-485 network, of which the transmission distance is over 12km whiletransmitting data. RS-422RS-232/RS-422,,,,.RS-232TXDRTSDTR,TXD.. RS-422 is a general RS-232/RS-422 converter with low cost, using mini exterior designand equipped with pluggable terminals,so it enjoys simple and convenient installation andcompact size. It can take power from TXDRTS and DTRsignals of RS-232 interface, and can also operate normally even if there isonly TXD signal supplying power. It is widely used in such systems as attendancechecking, entrance guard, PTZ control, meal sellingand park lot etc. feature ,,. Compact size, simple and convenient installation, high acceptance sensitivity , Thetechnology to take power from specific serial port with on need for additional power ,, Extremelylow power consumption ensures that serial port can still work normally whenthree lines are operating, DSAC, UseDSAC technique to distinguishand control data transmission direction automatically .

It can prolong communication distance 300m and support128 contacts. Full-duplex communication supports the transfer from RS-232 to RS-422/RS-232to RS-485. It is widely used in industrial automatic control system, card accesscontrol system, parking lot system, automatic bank system, automobile chargingsystem, attendance management system and toll station system etc.
