Vertiv USB485I interface cards/adapter

2000V RMS optical isolation. 460.8 kbps data rate. Powered by USB port. High-retention USB port. USB cable included. How It Works. Supporting two-wire RS-485. communications, Model includes. circuitry with 2000 volts isolation to. protect against ground loops and voltage. spikes. This model uses a pluggable. terminal blocks on the RS-485 side. Two light-emitting diodes (LEDs) indicate. whether data is being transmitted or. received. The converters draw power. from the USB port, so no power supply. is required (USB cable included). Ensure Secure Communication. No special software is required to. control the RS-485 converter. The driver is automatically enabled. when the converter is plugged into the. RDU101 card. The USB485I uses a pair. of wires to send a differential signal over. distances up to 1000 feet without a. repeater. The differential signal is ideal. in applications that require security, noise. immunity and long-distance. RS-485 is. capable of multi-drop communications –. up to 32 nodes. Ports & interfaces.
