FEATURES
- 100% Brand New
- It only requires 3 lines (RX, TX and GND) to get communication, making it great for troubleshooting your serial system.
- Supports reliable signal transmission over long distance: up to 4000ft over RS485 link at a high speed.
- Supports 2 wire half duplex communication; point to point, point to multi-point network.
- 600W static surge protection protects your value devices while ensuring high speed data communication.
- With ADDC (Automatic Data Direction Control) function to detect the incoming/outgoing data and automatically switch into the send / receive mode.
- It comes with a well labeled terminal block, making your wiring a breeze.
- Get Reliable Asynchronous Signal Conversion over Long Distance
- 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.
- 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.
