1. Overview
The EM7162 is an evaluation module that permits easy evaluation of the characteristics of the
CDM7162 carbon dioxide (CO2) sensor module. The module is equipped with a USB connector to
output CO2 concentration measurement data, a terminal for output of the concentration signal in PWM
format, and a terminal for output of a voltage signal converted from PWM output. After installing the
measurement data management software in an external computer and connecting EM7162 with the
included USB cable, this module can be powered through the USB cable. As measurement data output
is transferred to the computer, a chart of CO2 concentration is displayed on the computer monitor in
real time.

3. Setting the Method of Serial Communication
The I2C bus or UART interface can be chosen for serial communication between the CDM7162 CO2
sensor and this evaluation module.
Set the serial communication method by using the communication mode selection switches on the
EM7162 module before connecting the USB cable or the power supply.
Caution‼ Before changing the serial communication setting, be sure to turn off the power
switch (SW1) by setting it to the lower position as shown in Fig. 2.
3-1) Switch settings for I2C bus mode
Set switches SW2, SW3, and SW4 (1 to 4) as follows:
SW2, SW3: Set to I2C position (lower position as seen in Figure 2).
SW4-1, SW4-2: Set to ON position (upper position as seen in Figure 2).
SW4-3, SW4-4: Set to OFF position (lower position as seen in Figure 2).
Figure 2 - I2C Communication Setting
Caution‼ Do not change the preset positions of SW2, SW3, and SW4. Changing switch
positions may cause damage to the CDM7162 sensor.

3-2) Switch settings for UART interface
Set switches SW2, SW3, SW4 (1 to 4) as follows:
SW2, SW3: Set to UART position (upper position as seen in Figure 3)
SW4-1, SW4-2, SW4-3, SW4-4: Set to OFF position (lower position as seen in Figure 3).

Caution‼ Do not change the preset positions of SW2, SW3, and SW4. Changing switch
positions may cause damage to the CDM7162 sensor.
3-3) Attaching CDM7162
The included CDM7162 sensor module is attached to the EM7162evaluation module at the factory.
When replacing the CDM7162or removing and remounting it, match the pin # of connectors CN1
and CN2 on EM7162with the corresponding pin # of the CDM7162(Figure 4).
Caution‼Before mounting or removing CDM7162, be sure to turn off the power switch (SW1)
by setting it to the lower position as shown in Fig. 4.
Note) The standard CDM7162CO2sensor module is not equipped with pin terminals for connection.
If you purchase additional CDM7162sensor modules, solder commercially available pin
terminals to the CDM7162and mount onto the evaluation module.

4. Installing the Measurement Data Management Software and USB Driver
Before installing the USB driver, check the version of Windows OS on your computer by following
the description on the Microsoft website.
Microsoft website:
(1) Check the version of Windows:
https://answers.microsoft.com/en-us/windows/wiki/windows_10-windows_install/how-to-find-o
ut-the-version-of-windows-that-you/9cd9df62-b195-4875-8b9c-76dcc37aef65
(2) Check whether the Windows OS is a 32-bit version or a 64-bit version:
https://support.microsoft.com/en-us/kb/827218
