The EM7000 communication board is designed to transfer output from EM series sensor evaluation
modules to an external computer for facilitating evaluation of the characteristics of various Figaro gassensors. This communication board is equipped with a USB connector to transfer output data from theEM series evaluation modules to a PC via serial communication, an output terminal for gas
concentration data in PWM format from the CDM series CO2 sensor, as well as a terminal for voltage
output that is converted from PWM output. It facilitates an easy start to evaluating the characteristics ofFigaro gas sensors.
Once the PC application software is installed on an external PC, it allows for the transfer ofmeasurement data in serial format to the PC and the graphic display of output data on the PC monitor.
Measurement data can be imported and saved in CSV format on the computer using the PC application
software, then after gas measurements, it can be utilized for manual data processing and analysis using
other software, such as Microsoft Excel (Note 3).
The communication board includes a Mini-B USB cable. The PC application software can be
downloaded from the Figaro website. Please note that Figaro gas sensors or EM series evaluation
modules are not included, but they can be purchased separately depending on evaluation needs.

６．Using EM700 without Connecting to a Computer (for evaluation of CO2sensors only)
If the EM7000 is used without connecting to a computer, connect the 5VDC power supply between
the power input terminal and the ground terminal (see Figure 1).
- The PWM output terminal provides the PWM output signal with a 1 kHz cycle from CDM716x.
At the default setting of the CDM716x, a PWM duty ratio of 0 ~ 100% corresponds to 0 ~ 5,000ppm CO2.
- The voltage output terminal provides the concentration signal in a voltage that is converted fromthe PWM output. At the default setting of the CDM716x, the output voltage of 0 ~ 5 V corresponds
to 0 ~ 5,000 ppm CO2.
- The alarm output terminal provides the CMOS signal output according to the CO2 concentration.
At the default settings of CDM716x, CMOS output is High when the CO2 concentration is 1,000 ppm
or higher, and CMOS output is Low when the CO2 concentration is less than 900 ppm.

７．Notes7-1) Cautions in connection between EM7000 and a computer- Be sure to mount the CDM716x and the EM evaluation modules onto EM7000 before
connecting EM7000 to a computer.
- Do not remove CDM716x from EM7000 while EM7000 is connected to a computer.
- Do not remove the cable connecting EM7000 and a computer while CO2
concentration is being measured by the PC application software.
7-2) Error messages of the PC application software
If an error message is displayed, check the following items:(Note that the details of the error message may vary depending on a faulty point or cause oferror.)(1) Error message: [It failed on COM Port Open.]- Check that the COM port setting is correct on the PC application software.
"FT232R USB UART" should be displayed in Device Manager on the computer.
- Confirm that CDM716x is properly mounted on EM7000.

(2) Error message: [It failed when Lamp Interval couldn’t get in I2C Communication.][Failed on Lamp Interval Data!]- The serial communication mode set on the communication board is not consistent with thecommunication mode selected on the PC application software screen.

Note: The EM7000 communication board is a tool for evaluation of the CDM716x and other
Figaro gas sensors using the EM series evaluation modules.
This board is not designed to be embedded in other devices.
