Bộ chuyển đổi RS-232 sang RS-485 3Onedata SW485A
The RS-232 port of SW485A adopts hole-type DB9 interface, which could connect to PC directly and obtain power from PC serial port via TXD, RTS and DTR signal line. SW485A can obtain enough power from those data/handshake signals regardless of whether the signal is high or low.
The design index of SW485A fully complies with the requirements of industrial standard. It’s receiving sensibility ranks top among its kind, which particularly suits for industrial system with requirement in fast collecting speed and large amount of data.
Features
Support bidirectional data conversion between 1 RS-232 serial port and 1 RS-485 serial port
Serial port has high sensitivity of receiving
Unique port-power technology, no need for external power supply
Low power consumption, equal to that of normal light-emitting diodes in static operation, can be truly called passive
Automatic serial port signal rate detection , zero-delay automatic forwarding
Serial port provides 600W surge protection and 15kV electrostatic protection
Support -40～80℃ wide operating temperature range
