1.3.1 Block description
USB B Client Connector
This connector provides the interface for connection to a USB Host or Hub port. The maximum cable
length is 5 meters, according to the USB 2.0 specification.
FTDI FT2232H
FT2232H Hi-Speed USB2.0 (480Mb/s) is a dual serial UART interface IC device. Operating system device
drivers are required in order to work with the one to provide the Virtual COM Port serial functionality.
Dual RS422 Level Shifter
The RS422 level shifter converts the signals provided by the FT2232H into the voltage levels required by
RS422 devices.
Dual DE-9P Connector (Male)
The DE-9P connector is configured in an industry standard (TIA/EIA-574) pin-out to provide connection to
RS422 peripherals through standard cables. See section 3.1.2
