Supports USB to RS485/RS232 communication (switched through a toggle switch).<br/><br/>2. Adopting the brand new CH343G chip, plug and play, compatible with Windows series, MacOS series, Linux and other systems.<br/><br/>3. On board TVS (transient voltage suppression tube) can effectively suppress surge voltage and peak voltage in the circuit, and prevent lightning and static electricity.<br/><br/>4. The board is equipped with self recovery fuses and protective diodes, which can ensure stable output of current and voltage, prevent overcurrent and overvoltage, and improve impact resistance.<br/><br/>5. Three LED indicator lights on board for easy viewing of power signal transmission and reception status.<br/><br/><strong><span style="font-size:20px">Product parameters:</span></strong><br/><br/>Product type: Industrial grade USB to RS485/232 converter<br/><br/>Communication speed: 50bps~1000000bps<br/><br/>Host interface: USB<br/><br/>Device interface: RS485/RS232 (switched by dial switch)<br/><br/>USB interface:<br/><br/>Working level: 5V<br/><br/>Interface form: USB-A type interface<br/><br/>Interface protection: 200MA recovery fuse, ESD static protection<br/><br/>Transmission distance: approximately 5 meters<br/><br/>RS485/RS232 interface:<br/><br/>Interface form: wiring terminals<br/><br/>Interface pins: GND, A+(TXD), B - (RXD)<br/><br/>Direction control: Hardware automatically determines and controls the direction of data transmission<br/><br/>Interface protection: Provides 600W lightning protection, surge and 15KV static electricity protection (onboard 120R balanced resistor)<br/><br/>Transmission distance: RS485 (approximately 1200 meters), RS232 (approximately 10 meters) under low speed conditions<br/><br/>Transmission mode: point-to-point (up to 32 nodes, with a maximum of 16 nodes.
