1 Overview
This document describes the details of the FIM application kit board. This board will be called in
advance FIM_APPKIT.
The FIM_APPKIT board provides the external interfaces needed to test the different FIM interfaces
available on the ConnectCore 9P 9215 and Digi Connect ME 9210 modules.
The FIM_APPKIT is designed to be connected to the ConnectCore 9P 9215 development board
and to the Digi Connect ME 9210 development board.
For the purposes of this document, and since the ConnectCore Wi-9P and 9P 9215 modules share
the same development board, the shared development board will be referred to only as the
ConnectCore 9P 9215 development board.
The FIM_APPKIT is powered from the base board where it’s connected.

5.2 Board configuration
The FIM_APPKIT board provides interfaces to test the different firmware implemented on the
FIMs of the ConnectCore 9P 9215 and Digi Connect ME 9210 modules. The FIMs are 8-bit
microcontrollers embedded in the main microcontroller of the ConnectCore 9P 9215 and the Digi
Connect ME 9210 modules.
To test an interface implemented on one of the FIMs, the correct configuration jumpers have to be
connected on the FIM_APPKIT.
In the FIM_APPKIT board the configuration jumpers are separated in three areas:
-ConnectCore 9P 9215 FIM0
-ConnectCore 9P 9215 FIM1
-Digi Connect ME 9210
The following figure shows the configuration area of the FIM_APPKIT.

In the following paragraphs the specific configuration for each interface will be described.
5.3 Types of interfaces
According to how the interfaces of the FIM_APPKIT are connected to the FIMs of the
development kits they are classified in two different types:
Dedicated interface: the interfaces of this type are duplicated in the FIM_APPKIT board,
one is connected to the FIM0 and the other one is connected to the FIM1. The UART and
the CAN are the dedicated interfaces implemented on the FIM_APPKIT. The advantage of
these interfaces is that they can be used at the same time in the two FIMs (i.e. CAN0 can be
connected to FIM0 and CAN1 can be connected to FIM1).
Shared interface: the interfaces of this type are connected to the FIM0 and to the FIM1.
Selection between FIM0 or FIM1 will be done with the configuration jumpers. These
interfaces cannot be used at the same time in two FIMs.

5.5 Interface specification
5.5.1 UART_0
A UART interface is provided in the FIM_APPKIT to test the UART firmware implemented on the
FIM0 of the ConnectCore 9P 9215 and Digi Connect ME 9210.
The UART_0 interface provides RXD, TXD, RTS and CTS signals. To test the UART interface
using two wire mode, only the TXD and RXD jumpers must be connected. To test the UART
interface using four wire mode, all the jumpers must be connected.
Eight LEDs are used to show the status of the four lines of the UART interface.
One 9-pin, sub-D, male connector is provided on the board to allow the UART interface to
communicate to an external serial port device like a modem or a PC terminal.
Note: there is an RS232 transceiver between the UART interface and the 9-pin connector.
The following figure shows the block diagram of the UART_0 interface.

FIM1 of the ConnectCore 9P 9215.
The UART_1 interface provides RXD, TXD, RTS and CTS signals. To test the two wire UART
interface, only the TXD and RXD jumpers have to be connected. To test the four wire UART
interface the four UART_1 jumpers must be connected.
Eight LEDs are used to show the status of the four lines of the UART interface.
One 9-pin, sub-D, male connector is provided on the board to allow the UART interface to

A CAN interface is provided in the FIM_APPKIT to test the CAN firmware implemented on the
FIM_0 of the ConnectCore 9P 9215.
One jumper (P10) is used on the board to connect or disconnect one 120R termination resistor to
the CAN bus. If the jumper is connected (default configuration) the termination resistor is
connected to the bus.
One 9-pin, sub-D, male connector is provided on the board to connect the CAN interface to an
external CAN port.
Note: there is a CAN transceiver between the CAN interface and the 9-pin connector.

5.5.5 USB device
One USB device interface is provided in the FIM_APPKIT to test the USB device interface for the
FIM0 and FIM1 of the ConnectCore 9P 9215 and Digi Connect ME 9210.
The interface is fully compatible with USB 1.1 and USB 2.0.
The USB device interface operates at low (1.5Mbps) speed.
The USB device interface provides a power save mode, controlled by the “USB_SPND” signal. A
pull-down resistor is used in the FIM_APPKIT to set the USB device interface to normal operation
if this signal is not connected (i.e. in the Digi Connect ME 9210).
The USB device interface allows for the enumeration function that allows software control of USB
enumeration, simulating the removal of the device from the USB cable.
The USB device interface is not self-powered. One +5V external power supply must be connected
to the VBus pin (pin-1) of the USB connector.
One USB type B connector is provided on the board for this interface.

5.5.6 SDIO-Card
One SDIO card interface is provided in the FIM_APPKIT to test the SDIO interface using FIM0
and FIM1 of the ConnectCore 9P 9215 and Digi Connect ME 9210 modules.
The SDIO interface supports 4-wire and 1-wire SDIO controllers. Due to the reduced number of
GPIO available on the Digi Connect ME 9210 module, the SD controller implemented on this
module is a 1-bit SDIO type.
The SDIO interface provides a card detect signal. This signal is connected in the ConnectCore 9P
9215 to an interrupt input (GPIO101/EINT3). This signal is connected in the Digi Connect ME
9210 to an interrupt input (GPIO9/EINT0).
The SDIO interface provides a write protect signal. This signal is connected in the ConnectCore 9P
9215 to an standard GPIO not assigned to the FIM. In the Digi Connect ME 9210 this signal is
connected to the GPIO6.
One SD Card connector is provided on the board for this interface.
