The USB2-F-1001 provides a simple method of adapting legacy serial devices with RS232 interfaces to modern USB ports. This is accomplished by incorporating the industry standard FTDI FT232R USB-Serial bridge chip.
Each USB2-F-1001 adapter contains a small internal electronic circuit board which utilises the FTDI FT232R, mounted inside a rugged plastic enclosure capable of withstanding industrial temperature ranges. The integrated electronics also include RS232 level shifters and TXD/RXD LEDs to provide a visual indication of data traffic through the adapter.
Flexible mounting allows the USB2-F-1001 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-B device connector for connection to an upstream host or hub port. RS232-level signals, including modem handshake signals, are available on an industry-standard DE-9P (DB9) connector. The maximum RS232-level data rate is 1 Mbps.
The USB2-F-1001 adapter require USB device drivers, available free from www.easysync-ltd.com, which are used to make the USB2-F-1001 appear as a Virtual COM Port (VCP). This allows existing serial communications software, such as HyperTerminal, to exchange data through the USB2-F-1001 to a legacy RS232 peripheral device.
In addition to the device drivers, a configuration utility is available to change the definition of Pin 9 of the D-sub connector. The USB-COM-Plus Configuration Utility is available free from www.easysync-ltd.com.
