The device features basic functions of USB to 2-channel 3KV isolation/6KV lightning protection high-speed RS485 conversion. The product is powered by a USB port and does not require an external power supply. It utilizes a unique zero-delay automatic transmit/receive conversion technology, making it plug-and-play compatible with all software. It also has transmit/receive enable control and enters a high-impedance state when not sending data, supporting multi-point communication.
Distinguishing itself from other similar inexpensive products in the market, this product offers the following features:
● Industrial-grade operating temperature range (-40℃ to +85℃)
● 3KV isolation (can withstand AC ~ 380V without damaging the USB port) and 6KV lightning protection (10/700us current wave, internal resistance of 40Ω) for the serial ports
● Built-in TVS protection for the gold-plated USB interface (±15kV in the air, ±8kV on contact)
● Equipped with 5 LED lights: red for power, orange for receiving on the two serial ports, and green for transmitting on the two serial ports.
