Detailed Product Description

SW485C port-powered converters change TD and RD RS-232 lines to RS-485/422signals.
All are port powered and feature Automatic Send Data Control , can working if
only have TxD signal provide power. RS485/422 interface adopt beforhand aggravate
design, extend RS232 signal to 6000 feet at 115200Bps
1, Plug and play, small volume, easy installation

2, Port-powered, high efficiency obtain electricity,can also worked on

3 lines 3, RS232 to RS485 or RS232 to RS422

4, Lowest consumption

5, Automatic send data control, auto distinguish and sense direction adout data transfer
6, Auto sense serial signal rate, zero delay automatic transmit

Standard Accord EIA RS-232, RS-485, RS-422 standard
