1 Introduction
1.1 System Overview
The connected instrument transmits and receives data on an IrDA interface. The Infrared
Interface Module (IRIM) allows the user to connect the Instrument to a specific USB printer,
serial printer or to a PC using a USB connector.The IRIM is a middleware for translating the
IrDA protocol to USB/Serial protocol as per user selection. A PC should be used for receiving
the data from IRIM through USB. If a photometer is connected, it transmits test results through
the IrDA according to the test method. The IRIM will receive the data through IrDA. IRIM will
receive and transmit the data to any one of the following channels as per user’s selection.
USB Printer•
USB COM Class•
Serial RS232•
1.2 Manual Overview
This manual serves as a reference for IRIM users and also for device firmware up gradation.
User must have prior knowledge of using windows based applications.

LED Indications:
POWER indicator will be illuminated if software is running.•
PC interface indicator will be illuminated if the PC interface mode selected and cable •
connected with PC.
USB printer interface indicator will be illuminated if the USB printer interface mode is •
selected and the cable is connected to printer.
Serial printer interface indicator will be illuminated if the RS232 printer interface mode is •
selected. It will not check presence of serial printer.
1.5 Power supply to IRIM
The IRIM gets optional power from two sources:
It will first get power from USB device if available1.
If USB device is not available, it will get power from 4xAA batteries.2.
Only one power source will be active based on the availability.
If the software is running the Power LED will be illuminated.

3 Start of Application
Infrared data from the instrument will be received by IRIM at 9600 Baud rate.
3.1 USB Printer interface mode
When the unit is switched "ON" it will be in the last selected interface mode.
Initially if USB printer is not connected the interface status LED will be illuminated.
If data arrives while the device is not ready, it will be lost.
3.1.1 Connection to USB printer
Connect the USB printer cable to USB host port next to RS232 DB9 connector .If the printer
is successfully connected and ready to print the LED in front of the USB printer port will
illuminate.
3.1.2 Data transmission
Keep the IRIM and the transmitting instrument (e.g. Photometer) in single line of sight (face
to face). Activate print command in the transmitting instrument. The data will be sent to the
IRIM board and it will be printed on USB printer.
Note: The IRIM software does not support and will not indicate any printer related errors
(Paper jam, paper tray empty, etc).
3.2 Serial interface mode
Press the SELECT key to scroll. The current SELECT functionality will exit and switch over to
serial printer mode.
The LED in front of DB9 connector will illuminate to indicate the serial interface mode.
3.2.1 Connection to serial printer
Connect the serial printer to the DB9 IRIM connector using a straight cable.
Serial straight cable Pin information
Pin 2 is connected to Pin2 of other DB9 connector
Pin 3 is connected to Pin3 of other DB9 connector
GND is common (Pin 5 to Pin 5)
If you want to see the result in HyperTerminal use Cross cable between PC and IRIM board:

3.2.2 Data transmission
The following settings should be entered in the HyperTerminal:
Start >> Programs >> Accessories >> Communications >> Hyper Terminal
Figure 5 Setting on HyperTerminal when PC used
for receiving
After configuration keep the IRIM and the transmitting instrument in single line of sight (face
to face). Activate print command in the transmitting instrument. The data will be sent to the
IRIM and will be printed by the serial printer.
Note: If the printer is not connected the data will be lost. Reset the serial printer settings if
firmware is changed.
3.3 PC interface mode
Press the SELECT key to scroll. The current functionality will exit and switch over to PC
interface mode.
3.3.1 Connection details
Connect the USB cable between the PC and the IRIM device port.

3.3.2 Data transmission
Before the IRIM can be used for the first time the correct driver must be installed.
Install the driver delivered with the IRIM.

Figure 8 CDC enumeration
Launch the HyperTerminal application and select the right Com port as indicated in the device
manager and set the following configuration.
Figure 9 CDC class settings
Note: The HyperTerminal resource should be closed before enumeration occurs.
After configuration keep the IRIM and the transmitting instrument in single line of sight (face
to face) as close as possible. Activate print command in the transmitting instrument. The data
can be seen on the HyperTerminal.
All three interfaces can be connected at power up. The interface can be selected by pressing the
SELECT key of the IRIM. On Power up the default mode is the USB printer interface mode.

4 Device Firmware Upgrade (DFU)
4.1 Programming with USB boot loader:
This IRIM board has a pre-programmed USB boot loader located in the "On-chip boot section"
of the AT90USB. This is the easiest and fastest way to reprogram the device directly over the
USB interface. The “Flip” PC side application, is available from the Atmel website, offers a
flexible user friendly interface to reprogram the application over the USB bus.
The “Flip” software is the tool used to upgrade the firmware (available freely in the Atmel
website).
http://www.atmel.com/dyn/products/tools.asp?family_id=604
The following steps should be completed to allow the device starting DFU mode, and load
the hex file:
Install Flip software (Flip version 3.0 or above is required)1.
Connect the IRIM board to the PC using the USB cable (Standard A to Mini B)2.
Push the ON/OFF (Hardware Boot loader) key and hold3.
Push the RESET key and hold4.
Release the RESET key5.
Release the ON/OFF key 6.
If your hardware conditions explained above are correct, a new device detection 7.
wizard will be displ ayed on the PC. Pleas e follow the instructions as shown
below (the INF file is located in the USB sub directory from Flip installation:
“Install path:\ATMEL\FLIP\FLIPx.x.x\usb”).
