Port-Powered RS232 to RS485 Converter Adapter

Port-Powered RS232 to RS485 Converter Adapter

FEATURES

  1. 100% Brand New
  2. It only requires 3 lines (RX, TX and GND) to get communication, making it great for troubleshooting your serial system.
  3. Supports reliable signal transmission over long distance: up to 4000ft over RS485 link at a high speed.
  4. Supports 2 wire half duplex communication; point to point, point to multi-point network.
  5. 600W static surge protection protects your value devices while ensuring high speed data communication. 
  6. With ADDC (Automatic Data Direction Control) function to detect the incoming/outgoing data and automatically switch into the send / receive mode. 
  7. It comes with a well labeled terminal block, making your wiring a breeze.
  8. Get Reliable Asynchronous Signal Conversion over Long Distance
  9. A built-in transient voltage suppressor (TVS) provides 600W surge protection for effectively protecting your value devices against high voltage spikes and ensuring high speed data rate up to up to 115200 bps.
  10. Up to 32 devices can be connected on one network to communicate over a single pair of wires (plus a ground wire), so you can connect multiple RS485 devices to one computer without repeater.
