Introduction
The T6613/6615
development kit is a
tool designed for
evaluating the
performance of the
T6613/6615 CO2
sensor. In addition, this
kit can be useful in
developing software
and/or firmware for
use in communication
with the T6613/6615 sensor.
The T6613/6615 Development Kit provides a graphical interface to
display and record CO2 measurements from the T6613/6615. The
software also allows for calibration of the sensor with respect to known
stable CO2 reference gas. The kit contains a USB drive preloaded with
the necessary software. The sensor uses a special USB cable provided to
connect to a PC; it is NOT intended for use as a standard USB cable.
This kit is intended for use by engineers and technicians who have a
general understanding of electronics integration and/or communication;
it is not intended as an end product. Although the included T6613/6615
CO2 sensor is a production PCB, it is not recommended to install it into a
final product for resale.
Key features include:
Note:
Hardware Installation
The T6613/6615 CO2 OEM module is a sensor on a printed circuit board
and should be treated as carefully as any other printed circuit board.
Take appropriate precautions to prevent damage from electrostatic
discharge, mechanical stresses, and thermal abuse during installation.
Please refer to ANSI/ESD S20.20-1999 for more information on
preventing ESD damage, and to IPC-610 Rev D for more information on
proper electronic assembly practices.
The software that comes with the T6613/6615 Development Kit has only
been tested on Microsoft Windows XP Professional, Service Pack 2.
While the software should work on all versions of Windows XP or later,
this cannot be guaranteed.
IMPORTANT:
Small profile of sensor allows for easy integration into any system.

The software comes on media that has an autorun.inf file in the root
directory. This file instructs the operating system to automatically load
all the files required. Insert the media into the PC and wait for the setup
program to start. Note that if you are using a Flash drive, you might first
be presented with the dialog box shown in Figure 1 on the next page. In
this case, select Install T6613/6615 Development Kit and click OK to
begin the installation process.

If you are running this application for the first time, an error message
appears that the communications port is not available. Continue running
the application. In the eCO2View Settings menu (Figure 18 below),
change the settings to the communications port to which the USB serial
port driver iterated (Figure 19 below).
The Setup Wizard installs a shortcut on the users desktop and a group in
the Start Menu. From the Start Menu (Figure 17 below), select
eCO2View from the T6613/6615 Development Kit option to start the
application.

If any of the above points are not met, inaccurate readings or even
damage to the sensor can occur. When simulating the environment, you
should remember several factors when developing a test to fully
encompass the reality of an application. Some of these factors include:

A single point calibration will set what the sensor believes is a single
concentration of CO2, and will shift each measurement correspondingly.
The CO2 concentration in an open area outdoors, free of any obstruction,
is typically around 380 to 400 ppm. This can serve as a reasonable single
point calibration concentration. There are alternative calibration
techniques. The first alternative is to soak the sensor in a known
premixed concentration of gas and then execute the single point
calibration sequence. If gas is being used, ensure the sensor readings are
stable to 10 ppm. The second alternative is to use the Telaire 7001
Reference sensor as a value for a single point calibration. To initial a
single point calibration, open eCO2View. Under the Calibration menu,
select Single Point Cal. A warning will appear specifying the proper
condition for calibration. After verifying all the condition are met for
calibration, select OK. A window similar to Figure 24 below appears:

Status:
Read a status byte from the sensor. The status byte indicates
whether the sensor is functioning, and is measuring PPM
concentrations. The response is a single byte, <status>, of bit
flags. (Note: bit 0 is the LSB.)
Bit 0: Error
Bit 1: Warm up Mode
Bit 2: Calibration
Bit 3: Idle Mode
Bits 4 - 6: (internal)
Bit 7: Self-Test Mode
If a given status bit is 1, the sensor is in that mode. If a status bit is 0,
the sensor is not in that mode.

In this set of interchanges, you first read the sensors elevation parameter
and find it is set at 1000 ft. Then you change the elevation setting to
2500 ft. Then you read back the new elevation setting and verify that it is
set to 2500 ft.

7. Select the desired binary file to transfer. The binary files included
are located in the folder named bin.
8. Click Open.
Clicking Open will send the desired command to the unit. The
HyperTerminal wont receive anything from the sensor, but the
command has been sent and the sensor has preformed the desired
operation. For a full description of the protocol, please see
