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, including RTS/CTS modem handshake signals, are available on an industry-standard DE-9P (DB9)connector. • The module is powered from the host USB port and therefore does not require an external power supply. • Pin 9 of the DE-9P (DB9) connector provides 5V power to external devices. The maximum power is 250mA dependent upon the capabilities of the USB host. • Local Echo of data may be enabled or disabled. • The maximum RS485 level data rate is 3Mbps. • The product works with the royalty free FTDI drivers for Windows, MAC, Linux. • The USB-COM485-PLUS1 is fully RoHS compliant and is CE and FCC approved. • Operating temperature range -40oC to +85oC
