The USB2-H-5002 is a USB to a dual interface RS485 level serial UART adaptor incorporating FTDI’s FT2232H Hi-Speed USB2.0 (480 Mb/s) to dual serial UART interface IC device. The FT2232H handles all the USB signaling and protocols. The adaptor provides a fast, simple way to connect devices with an RS485 interface to USB.
The integrated electronics of the USB2-H-5002 utilise the FTDI FT2232H and includes RS485 level shifters plus TXD/RXD LEDs to provide a visual indication of data traffic through the adapter.
Flexible mounting allows the USB2-H-5002 to be used in a variety of applications, from a portable adapter to accompany a laptop to permanent installations in industrial, commercial and retail locations.
The enclosure incorporates a standard USB-Mini-B client connector for connection to an upstream host or hub port. RS485-level signals are available on two industry-standard DE-9P (DB9) connectors. The maximum RS485-level data rate is 10 Mbps.
The USB2-H-5002 adapter require USB device drivers, available free from http://www.easysync-ltd.com, which are used to make the USB2-H-5002 appear as a Virtual COM Port (VCP). This allows existing serial communications software, such as HyperTerminal, to exchange data through the USB2-H-5002 to a legacy RS485 peripheral device.
Pin 9 of the D-sub connector can provide +5 V power output with maximum 250 mA.
