Bộ chuyển đổi Port-powerd RS-232 sang RS-485/422 3Onedata SW485C

Introduction:
The SW485C is an industrial grade bi-directional port-powered RS232 to RS485 or RS422 converter in a 9 pin format. It can convert any standard full duplex RS232 port to any two-wire balanced half duplex RS485 port or four-wire balanced full duplex RS485 or RS422 port. In simple terms, it will convert any RS232 signal to a RS485 or RS422 signal and vice versa. The unit is powered from the RS232 data lines. It also supports data direction auto-turnaround. Therefore, no external power or flow control is required. The data direction auto-turnaround automatically enables the RS485/RS422 driver when data is present on the RS232 side making the device plug-and-play, requiring no software drivers. The SW485C has a DB9 female connector on the RS232 side and either a DB9 male connector or 5 bit terminal block on the RS485/RS422 side.

Features:
1. Plug-and-Play, small volume, easy installation 
2. Port-powered, high efficiency obtain electricity, can also worked on 3 lines
3. RS-232 to RS-485 or RS-232 to RS-422
4. Lowest consumption
5. Automatic send data control, auto distinguish and sense direction adopt data transfer
6. Auto sense serial signal rate, zero delay automatic transmit.
