2x USB to RS485 Serial Converter Bidirectional Half-duplex Communication Module

USB 2.0 to RS485 Converter and all kinds of 485 interface docking, transmission distance up to 1000 meters Mainchip: CP2102(SILICON LABS), Industrial chip The Lead PINS include: A+, B-, GND, GND, 5V0 Industrial Product, With 15KV ESD protection and TVS overvoltage protection Features: 1. Industrial level protection: TVs transient suppression protection, ESD protection, surge protection, signal line short circuit and power supply short circuit protection (short circuit does not burn) 2. Transmission distance up to 1200 meters (tested at 9600bps) 3. Support the baud rate of 921600, which is much higher than 115200, and the baud rate of pairwise mutual transmission is higher 4. Multi system supports hot plug, WIN98 / 2000/2003/2008 / xp/wn7/wn8 / wn10 / Vista / Linux / OS X system, and USB interface can be hot plug 5. Automatic identification and control of data transmission direction, without any handshake signal (such as DTR, etc.) and without jumper setting, mode conversion can be realized to ensure compliance with existing communication software and interface hardware 6. With TXD, RXD indicator light Specification 1. Power supply: usb5v 2. Transmission distance: up to 1200m (9600bps) 3. Chip scheme: ch340 4. Communication protocol: hardware only, not limited by protocol 5. Baud rate: up to 921600bps, supporting mutual transmission supports higher baud rate 6. Protection: TVs transient suppression protection, ESD protection, surge protection, signal line short circuit and power supply short circuit protection (short circuit does not burn) 7. Temperature range: -40 Celsius - 80 Celsius 8. Provide external 5V power supply with fuse to limit current 9. Support system: support hot plug, support WIN98 / 2000/2003/2008 / xp/wn7/wn8 / wn10 / Vista/ Linux / OS X system, USB interface can be hot plug 10. Automatic identification and control of data transmission direction can realize mode conversion without any handshake signal (such as DTR, etc.) and jumper setting, so as to ensure compliance with existing communication software and interface hardware 11. weight: 32g colour: blue Material: ABS size: 70 x 27 x 13mm Package Contents: 2 x usb to rs485 communication module
