The USB-16COM Plus provides easy serial port expansion over USB 2.0 connecting to high speed RS232 or RS422/485 devices. The device is fully ESD and surge protected, bus powered and accommodated in a ruggedized metal housing. Furthermore, it can operate across a large range of temperature levels to cope with harsh operating conditions. The ISO version is 2.5kV electrically isolated to withstand unbalanced ground loops that arise in hazardous industrial environment. Lastly, both DIN-Rail and wall-mounting options are available.

Flexible Three-Way Serial Ports

The serial ports allow different operating modes — which are easily configured via a single DIP switch — to fully support RS232, RS422 and RS485 protocols. The operating mode of serial ports chosen via DIP switch is either same for all ports or individually for each port by "USBCOM Configuration Utility" software. The differential line termination for RS485 (120Ω) is automatically controlled by choosing the appropriate operating mode. High/Low biasing resistors are not needed; as such, hassle-free usage is guaranteed for the user.
Models marked with "232" are fixed to the RS232 mode. Com Port drivers are available for Windows, Linux and Mac OS X. A configuration tool allows easy access to special Windows driver options.

High Speed and Isolation

USB 2.0 High Speed connection allows serial data rates of up to 12Mbps for RS422/485 and 921.6kbps for RS232. Every non-standard bitrate (e.g. 500kbps) can easily be set up in the range of up to 3.5Mbps.
USB-xCOM Plus adapters are 16kV ESD and surge protected at USB and serial ports interfaces. Additionally, the serial ports are 2.5kV electrically isolated (ISO version only), making them ideal for deployment in harsh industrial environments.

Power and Port Expansion

Multiple USB-xCOM Plus devices can be concatenated via the USB Type A at the rear side, creating up to 32 serial ports. In concatenated configuration, the local power input of each expansion module must be used.
Standard drivers are available for all major operating systems.
The USB 2.0 High-Speed enables serial data rates of up to 1000kbps in RS232. The device also allows every non-standard bitrate up to max. speed.

A USB-out (type A) connector at the rear side allows easy expansion of serial ports by simple concatenation of further USB-COM Plus modules; we call it "USB-Through" feature.

The really small and robust embedded system! Low Power Consumption, Professional construction inside!
