Product Overview

The USB-COM485-PLUS1 module is a single channel USB to RS485 communication device. The integrated electronics of the USB-COM485-PLUS1 utilise the FTDI FT232R and includes RS485 level shifters plus Power/TXD/RXD LEDs to provide a visual indication of data traffic through the module. The module uses a standard USB-B device connector for connection to an upstream host or hub port. RS485-level signals are available on an industry-standard DE-9P connector. The maximum RS485-level data rate is 3Mbps. Pin 9 of the DE-9P connector can provide +5V DC at 250mA. The USB-COM485-Plus1 module requires USB device drivers, which are used to make the USB-COM485-Plus1 appear as a Virtual COM Port (VCP). This allows existing serial communications software such as HyperTerminal to exchange data through the USB-COM485-Plus1 to a legacy RS485 peripheral device.
