The modern USB-4COM Plus 232 adapter connects 4 x RS232 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-4COM Plus 232 works in bus-powered mode, but a DCin connector for external wide range voltage is also provided.
All serial ports support RS232. Standard Drivers are available for all major operating systems.
The USB 2.0 High-Speed enables serial data rates of up to 1000kbps. The device also allows every non-standard bitrate.
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.
