תיאור

 

    • This converter is compatible with RS-232C,RS-485,RS-422 standard ,enable transfer RS232 Signals to Balance Difference RS485 or RS422 signal.

 

    • Converter can extends RS232's transmission distance to 1.2KM, drive by using special RS232 charge pump without external power, get power withoutinitialized RS

 

    • 232.Inside,there is zero-delay auto transfer, and unique I/O circuit automatically controlling Data flow direction without any hand-shake signals(e.g.:RTS,DTR,etc).

 

    • The exchange of Full-duplex (RS-422) and Half-Duplex modes can be realised without jumper,so it ensure the programm under the way of RS232 full-duplex and half-duplex to

 

    • run without any modification, so to ensure it compatible with current operation software and interface hardware, and transmission speed as 300-115.2Kbps.

 

    • It can be used between main controllers,between main controller and panel machine or external equipment to creat point-to point,point-to-multipoint remote multi-machine

 

    • telecommunication network and multi-response communications

 

    • Interface feature:meets or beats EIA-232 to EIA-485 and EIA-422 Specifications(with external power)

 

    • Electronic Interface:DB-9 hole connector of RS-232,DB9 pin connector of RS485/RS422, posts

 

    • Working method:Asynchronous full-duplex,half-duplex Differential transmission automatic selection,no need jumper setting

 

    • Transmission Media:shielded twisted pair or line

 

    • Transfer speed:300-115.2KBS

 

    • Dimensions:60mm x 35mm x 18mm

 

    • Using environment:-25 degrees to 70 degrees,and relative humidity of 5% to 95%

 

    • Transmission distance:1200 meters(RS-485 terminal);five meters(RS-232 terminal)
