High-quality USB to RS485 Serial Converter Cable by PIISUN.
Incorporates FTDI's FT232RQ USB to serial UART interface IC device for reliable performance.
Enables fast and easy connection between devices with RS485 interface and USB.
Features a small internal electronic circuit board with integrated RS485 transceiver.
Tx and Rx LEDs provide visual indication of cable traffic.
Customizable connectors available to support different applications.
Professional-grade product designed for seamless data transmission.
Ideal for industrial automation, control systems, and other RS485-based applications.
Ensures stable and reliable communication between USB and RS485 devices.
Compatible with various operating systems, including Windows, Mac, and Linux.
The USB-RS485 cable is a USB to RS485 levels serial UART converter cable incorporating FTDI’s FT232RQ USB to serial UART interface IC device which handles all the USB signalling and protocols. The cable provides a fast, simple way to connect devices with a RS485 interface to USB. Each USB-RS485 cable contains a small internal electronic circuit board, utilising the FT232RQ, which is encapsulated into the USB connector end of the cable. The FT232RQ datasheet, DS_FT232R, is available at https://ftdichip.com/. The integrated electronics also include the RS485 transceiver plus Tx and Rx LEDs which give a visual indication of traffic on the cable (if transparent USB connector specified). The other end of the cable is bare, tinned wire ended connections by default, but can be customised using different connectors to support various applications. The USB-RS485 cable is designed for use at the end of an RS485 network up to approximately 10m. For longer networks or placement of the USB-RS485 cable in the middle of an RS485 network it is recommended that the attached wire is cut to 20cm or less to ensure signal integrity. Cables are FCC, CE, UKCA and RoHS compliant
