The USB-16COM Plus actually is a combination of two USB-8COM Plus, mounted as a pair via a special Rack Mount kit. Both devices are connected via one USB cable, in essence the pair operates as one USB-COM Plus with 16 simultaneous serial ports.
As the separate modules the USB-16COM Plus adapter connects 16 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. All USB-COM Plus devices can be used to expand the serial ports for NetCom Plus Device Servers.
