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.
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 serial ports, USB and the power supply are ESD protected, compliant to IEC 61000-4-2
(8kV contact/16kV air discharges).
