Included is your choice of a Critical Link MitySOM-1810, MitySOM- 1808, MityDSP-6748F or MityDSP-L138 series System on Modules. In addition, the Industrial IO Development Kit includes on board RS-232, 10/100 MBit Ethernet, Universal Serial Bus (USB) Host and USB-On The-Go (OTG) communication interfaces and an Electrically Isolated CAN interface. The single UART expansion port allows for the connection of either the PROFIBUS(module dependent)/RS-485 expansion board (optional) with 2500V galvanic isolation barrier or a simple RS232 serial port expansion kit (optional). Integrated Digital Video Interface (DVI) controller for external display connection with DDC support. Interface to QVGA WQVGA display via 5 pair LVDS link with additional SPI interface for resistive touch controller (requires an FPGA based module to be installed), Multi Media Card (MMC) interface, 3 I/O Expansion connectors for custom add-on card and integrated power supply with +3V/+5V/12V outputs from single 12VDC input. 1 Copyright 2007-2013, Critical Link LLC Critical Link, LLC Industrial IO Development Kit www.CriticalLink.com 6 March 2014 A block diagram of the Industrial IO Development Kit is illustrated in Figure 1. All available processor GPIO ports and FPGA I/O lines (if FPGA module is installed) are either used directly by the Industrial IO Development Kit or are routed to the 3 50-pin Expansion IO connectors. Control of the on-board interface hardware and connected Expansion IO cards require proper configuration of the MitySOM / MityDSP ARM, DSP, and FPGA. While not required, it is strongly recommended that the MitySOM software and firmware development kit and supplied API be used to manage these interfaces.

The serial interface is routed to the primary MitySOM / MityDSP serial bootloading port in order to allow remote code download and FLASH upgrades on an attached MitySOM / MityDSP from this connector. USB Interface Description The on-board USB interface utilizes dedicated HOST and OTG controllers inside OMAP processor. Linux drivers are available. 2 Copyright 2007-2013, Critical Link LLC Expansion Header 3 2x25 2-mm
