Each point-to-multipoint converter can connect to 256 rs422, rs485 interface devices, data communication rate range of 300-3000000bps. Three data indicators Easily see the working state, for your programming debugging to provide convenience. Be more thoughtful than you think and avoid minefields When connecting cables from usb to rs485 and rs422 9-pin terminals cannot be directly connected. Instead, the terminals can be connected only through the terminals provided with the products. Support for multiple technologies Compatible with usb2.0, rs485, rs422 standard protocols. Automatically determine and control the direction of data transmission. Automatic detective serial port signal baud rate. Filter magnetic ring signal enhancement  With filter magnetic ring, signal transmission is more stable. Zero delay transceiver conversion The converter has zero delay transceiver conversion to ensure high-speed data transmission without delay, to ensure that the signal faster running, for your communication to provide a reliable connection. Ⅲ. Product Size      

High gain, high receiving sensitivity, and very strong wall penetration ability. At the same distance, compared with LORA products, it can transmit more data and the transmission speed is faster. At the same time, the amount of data will not lose packets, which solves the problem of LORA's small amount of data for long-distance transmission, the problem of packet loss.

Meets various interface requirements, making work and use more convenient.
