Description: Main function The dtech USB 2.0 to RS422/RS485 interface converter supports the following four communication modes 1. Point-to-point/four-wire full-duplex; 2. Point-to-multipoint/four-wire full-duplex; 3. Point-to-point/two-line half-duplex; 4. Point-to-multipoint/two-wire half-duplex When the converter is connected as a full duplex or half duplex, a matching resistor (120 ohm 1/4W) should be connected at the end of the line to prevent signal reflection and interference. Three, hardware installation and application -Before installing the USB to RS485/422 interface converter, read the product manual carefully and connect the communication cable provided with the product to the USB port. This product uses USB/DB-9 and the universal connector is input/output -The interface automatically realizes RS422 or RS485 communication mode without jumper setting. It can be connected and disassembled easily by twisted pair or shielded cable. Four wires T/R , T/ r-rxd , and RXD- are connected for point-to-point, point-to-multipoint, full-duplex communication. Two wires T/R and T/R- are connected for point-to-point, point-to-multipoint, half-duplex communication. performance parameters: 1, standard: in line with USB2.0 standard, downward compatible, in line with RS422, RS485 standards; 2, USB signal :VCC, DATA , DATA-, GND; 3, RS422 signal: T/R , T/R-, RXD , RXD-, GND; 4RS485 signal: T/R , T/R-, GND; Working mode: asynchronous operation, point-to-point or multi-point, 4-line full-duplex, 2-line half-duplex; Direction control: using data flow automatic control technology, automatic discrimination and control of data transmission direction; Baud rate :460800bps.
