Application requirements mean that customers are increasingly looking for solutions which are equipped with an increased number of COM ports. In response to these demands, NEXCOM has introduced a USB to COM module which enables the user to expand the number of COM Ports. The NEXCOM USB to COM port is specifically designed for award winning NISE fanless computer system, but is also suitable for use with other NEXCOM products. Housed in a compact 52mm (W) x 72mm (H) enclosure, the module is available in two formats, the first has a RS485 output, and the second is with dual RS485 output via USB cable connector. With external switch, RS485 mode can be switched to RS422 to meet the needs. Both US485I and UD485I have 2.5KV isolation protection and are therefore designed to avoid the potential severe damage of components connected to the bus. The uCOMM also provides +/-15KV ESD protection on transceiver interface using the human body model (HBM). These designs enhance the reliability of uCOMM when running in a harsh environment.
