Hi-Speed USB to 4 Port Serial RS232 / RS485 Industrial Adapter

Description

The USB2-H-9004-M adapter provides a simple method of adapting four legacy serial devices with RS232 or RS485 interfaces to a modern USB 2.0 Hi-Speed port. This is accomplished by incorporating the industry standard FTDI FT4232H USB to Serial bridge chip mounted inside a metal enclosure capable of withstanding industrial temperature ranges. The integrated electronics includes RS485 level shifters and RS232 level shifters plus TXD/RXD LEDs to provide a visual indication of data traffic through the adapter. Selection of RS232 or RS485 signaling is made using DIP switches on the front of the adapter. Each of the dual channels can be independently configured as either RS232 or RS485. The USB2-H-9002-M adapter requires USB device drivers, available for free for Windows, Mac OS X, and Linux platforms.
