DESCRIPTION
The Industrial IO Development Kit provides all the hardware and software support for
system designers and developers to evaluate the AM1810, AM1808 or OMAPL138
Microprocessors. 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.

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.

RS-232 Interface Description
The on-board RS-232 level driver provides standard serial interface at data rates up to
115,200 baud. 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.

Ethernet Interface Description
The on-board Ethernet interface features a network PHY capable of running at
10/100Mbit including link auto-negotiation and MII/MDIO capability. An industry
standard RJ-45 connector is provided for external connection. This Ethernet interface
may be used to perform remote code download and FLASH upgrades on an attached
MitySOM or MityDSP module.
QVGA/WQVGA LVDS Interface Description
The Industrial IO Development Kit provides a flat-ribbon cable low profile interface for
five Low Voltage Differential Signaling (LVDS) pairs
.
The interface design is intended
to support high speed off board interconnects. In addition to custom user interfacing, the
pairs may be used to interface to a Quarter VGA LCD screen using the MitySOM /
MityDSP hardware and software development kit LCD interface libraries and an
appropriate daughterboard interface. Off-the-shelf display solutions for WQVGA
interfaces are provided by Critical Link.
The interface can also be customized to support 17 IO lines at +3.3V CMOS/LVTTL
signaling levels based on FPGA configuration. This interface is available only with an
FPGA based MitySOM or MityDSP module installed.
DVI Interface Description
The Industrial IO Development Kit provides a standard DVI interface for external
monitor connection. Based on CPU utilization, recommended resolution should be
limited to VGA (640x480) with 5-6-5 color pallet.
CAN Interface Description
The on-board CAN provides a CAN V2.0B compliant interface. This interface is
managed by a Microchip MCP2515 CAN controller connected to MitySOM / MityDSP
via the SPI1 interface. The galvanic isolation is provided by a dedicated TI ISO1050
transceiver. The ISO1050 is powered by an isolated power supply with 1000V* isolation
from the primary supply.
Jumper JP504 can provide dedicated bus termination of 120Ohm. To enable termination,
place shorting jumper across JP504.
The Electrical interface is provided via J501, 10-pin shrouded header.
Linux Driver and API examples are available to support CAN functionality.

UART Expansion Interface Description (80-000268RI-2 Assemblies)
The on-board dedicated UART port provides standard serial interface at data rates up to
115,200 baud. The serial interface is routed to the UART2 serial port of MitySOM /
MityDSP. This expansion port can accept an optional PROFIBUS/RS485 Expansion
Board or an RS232 Expansion Board. Please contact your Critical Link representative.
See the compatibility chart below to determine which modules can support the
PROFIBUS protocol.

The port also provides a +5.0V@100mA power via isolated power supply with 1000V*
isolation from the primary supply as well as +3.3V@300mA from the main non-isolated
power supply with a common ground. A single enable GPIO is also routed to this port in
addition to the TX and RX UART signals.
The Electrical interface is provided via J504, 10-pin shrouded header
When the PROFIBUS/RS485 Expansion Board is used it provides galvanic isolation by a
dedicated TI ISO1176 transceiver. The ISO1176 is powered by an isolated power supply
with 2500Vrms* isolation from the primary supply. Jumpers on the PROFIBUS/RS485
Expansion Board can provide dedicated bus termination.
Please see the PROFIBUS/RS485 Expansion Board documentation found here:
http://www.mitydsp.com/products-services/base-boards/interface-modules/expansion-profibus-rs485/
When the RS232 Expansion Board is used the transceiver on it is powered from the
+3.3V supply of the Development Kit. It does not provide any isolation.

Note: On older Industrial IO Development Kit base boards, 80-000268RI-1 assemblies,
the PROFIBUS/RS485 hardware was installed directly on the base board. The expansion
board was not necessary and therefore not included. Please contact Critical Link for
details or a previous datasheet if necessary.

The Industrial IO Development Kit includes a battery used to provide power to the
installed modules real time clock. This battery has been sized to allow for approximately
6 months of unpowered time with a module installed until the battery will be depleted.
