| SW485C รหัสสินค้า: 000465 รายละเอียด: Products Content:
The product SW485C port-powered converters convert TxD and RxD RS-232 lines to RS-485/422 signals. 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
Features
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
