USB to RS-485/422 8 Ports Converter with Isolation
This product is a universal USB to RS422/485 converter, compatible with USB, RS422, RS485 standards, can convert single-ended USB signals into 8 RS422/485 signals, providing surge protection power per line, ensuring RS422/ The high-speed transmission of the 485 interface, the RS422/485 terminal is connected through the connector of the DB9 male connector, which makes it easy to realize the data transmission between the computer host of the USB interface and the multi-channel RS422/485 bus system and the device.
Main communication methods:
1. Point-to-point four-line full-duplex; 2. Point-to-multipoint four-line full-duplex; 3. Point-to-point two-wire half-duplex; 4. Point-to-multipoint two-wire half-duplex
When the converter is used as full-duplex or half-duplex wiring, in order to prevent signal reflection and interference, it is necessary to connect a matching resistor at the terminal of the line (parameter: 120 ohm 1/4W).
Performance parameters:
Comply with USB1.0, 1.1, 2.0 standards;
Compliant with EIA RS422, EIA RS485 standard
USB signal: VCC, DATA-, DATA+, GND
RS-422 signal: T/R+, T/R-, RXT+, RXD-, GND; RS-485 signal: T/R+, T/R-.GND
RS-422 working mode: point-to-multiple full-duplex two-way communication
RS-485 working mode: point-to-multiple half-duplex two-way communication
Maximum transmission distance: USB port does not exceed 5 meters, RS-422/485 terminal 1200 meters (9600bps)
Transmission medium: twisted pair or shielded cable
Load capacity: RS-422, up to 10, including the main equipment; RS-485, up to 32
Baud rate: 300 baud to 230400baud automatically detects the serial port transfer speed;
Flow control: none, hardware and xon/xoff
Interface protection: surge protection, ±15KV static protection
Signal indicator: send (TXD), receive (RXD)
USB cable with magnetic ring, shielded, can resist signal interference;
Optional DC jack (DC 5V) or patch panel power connection (9-36 DC)
