The modern USB-8COM Plus adapter connects 8 x RS232 or RS422/485 devices to your PC by one USB 2.0 High
Speed port. The serial ports, USB and the power supply are ESD protected, compliant to IEC 61000-4-2 (8kV
contact/16kV air discharges). USB-8COM Plus may work in bus-powered mode on stronger than minimum ports, but a
DCin connector for external wide range voltage is provided.

All serial ports support RS232, RS422 and RS485 in Full-/Half-Duplex operation modes. The operation modes of the
serial ports are either configured by a single DIP switch common for all ports, or for each port individually by software.
The configuration also activates built-in RS485 termination if required, no jumpers needed. Standard Drivers are
available for all major operating systems.

The USB 2.0 High-Speed enables serial data rates of up to 12Mbps in RS422/485 or 1000kbps in RS232 modes. The
device also allows every non-standard bitrate up to 3.5Mbps.

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.
