1. Introduction
The CL-200 series of data logger devices can be used to record PM2.5, CO, CO2, H2S,
NH3, HCHO, TVOC, temperature, humidity and dew point information, including the
date and time stamps, and are able to store up to 450,000 downloadable records.
Real-time data can be accessed from the CL-200 data logger from anywhere and at any
time using the free Windows software, the iOS App, or the Android App, as long as they
are connected to the same local network as the data logger.
The CL-200 series module contains RS-485, Ethernet and PoE communication
interfaces, the most common communication interfaces in industrial network. With
additional Wi-Fi interface, the CL-200-WF series provides a WLAN connection which
makes an easy way to incorporate wireless connectivity into monitoring and control
systems.

Features
NDIR Sensor
NDIR (Non-Dispersion Infrared) is based on one of the natural properties of CO2
molecules: CO2 molecules absorb light at a specific wavelength of 4.26 µm. This
wavelength is in the infrared (IR) range. High concentrations of CO2 molecules
absorb more light than low concentrations. NDIR sensor can detect fast and
accurately in a wide range of CO2 concentration.
Built-in Web Server
With the built-in Web server, users can easily log in to the CL-200 module via a
standard web browser to monitor the data and configure the settings without install
any software in the terminal. Please note that the web server is only available to the
Ethernet interface.
Get Real-time Data Anywhere and Anytime
iAir App for iOS or Android Phones or Tablets is free and easy to install, it can
obtain the real-time data from CL-200 modules over a Wi-Fi network anytime and
anywhere. The iAir App can link to the CL-200 modules by specifying IP addresses
or by searching all the modules connected to the same Ethernet segment.
Data Logging Software
The DL-300 Utility can be used to configure the modules, monitor real-time data
and show the run chart, log alarm events, group CL-200 modules so that the status
of distribution groups can be
viewed and managed. The
utility also allows the log data
to be downloaded and
exported to a .CSV file that
can then be imported into
any industry-standard
software or spread sheet for
analysis.

Easy integration with SCADA software
Modbus is one of the most popular protocols used in the industrial world.
Supporting traditional serial protocols of RS-485 and Ethernet protocols allow the
CL-200 series well-integrated into the HMI/SCADA systems.
Alarm
CL-200 series allows users to set high alarm level for PM2.5/CO/CO2/H2S/NH3/
HCHO/TVOC/Temperature/Humidity/Dew Point and low alarm level for
Temperature /Humidity /Dew Point, and to enable/disable the alarm functions. An
Alarm LED indicator on the front of the CL-200 module will flash when an alarm
event is activated, and a relay output related to all alarm events can be use to tap
an alarm light/sound or control the IAQ devices such as ventilators, air cleaners,
and filters. Beep alarm is available when the CO/CO2/H2S/NH3/ HCHO/TVOC high
level alarm occurs.
Automatic Baseline Correction
The built-in ABC algorithm makes the CO2 sensor on the CL-202, CL-212, CL-203,
CL-213, maintenance-free. In most indoor applications, the carbon dioxide level
drops to nearly outside air - 400 ppm, and then the ABC algorithm constantly keeps
track of the lowest reading and slowly corrects it as the expected fresh air value of
400 ppm. The ABC algorithm can not apply for the places where are no periods that
the CO2 concentration drops to background level such as greenhouses, hospitals,
24-hour operation factories or stories. The ABC function needs be disabled where
the spaces the CO2 concentration may be elevated at all times.
Easy Wiring
Support for RS-485, Ethernet and Power over Ethernet (PoE) interfaces for users
to choose the appropriate one to meet the field requirements.
Power over Ethernet (PoE)
The CL-200 series features true IEEE802.3af-compliant (classification, Class 1)
PoE technology that allows both power and data to be carried over a single
Ethernet cable. PoE provides a unified power system, as well as backup provisions
for critical building functions, without any additional cables, outlets or connections.
It can reduce the power supply wiring and maintenance costs, and improve system
scalability.

2.4 Cabling for Power and Network
Note
Do not install the CL-200 module near a vent, a ventilation fan or a door where the
air flows faster.
Avoid installing in locations where the temperature is below 0°C or above 50°C.
Avoid installing in locations near a strong electromagnetic field.
For connecting with a PC or a Android device
The CL-200 logger can connect to a PoE network without a power source or connect to
a non-PoE network. When using the Search function in iAir App on Android or iOS
mobile devices, mobile devices need to connect to the same subnet that the CL-200
connected to over Wi-Fi. Similarly to using the Search function in DL-300 Utility running
on Windows, the module and the host PC need to connect on the same subnet, too.

RS-485 Network
CL-200-E
Power Supply
USB/RS-485Converter
I-7561
CL-200-E
devices on the same subnet can be searched out. It means that the host PC, Android
devices and the logger must have the same broadcast address. The broadcast address
for an IPv4 device can be obtained by performing a bitwise OR operation between the
bit complement of the subnet mask and the IP address for a device. In other words, take
the device's IP address, and set to '1' any bit positions which hold a '0' in the subnet
mask.
For example, in an entire IPv4 subnet, the host PC or the Android device uses the
private IP address space 172.16.0.0/12 and subnet mask address 255.240.0.0, the
broadcast address is 172.16.0.0 | 0.15.255.255 = 172.31.255.255. Only the loggers
which have the same broadcast address could be searched out in the iAir App or
DL-200 Utility. Please contact with your network administrator to make sure the CL-200
logger is connected to the same sub-network that your Android devices or PC is
connected to.
For connecting with PC via RS-485 network
The CL-200 logger can connect to the PC through a RS-485 network with power input
requirement of +12 ~ +48 VDC.

For connecting with PC via Wi-Fi
The CL-200-WF logger can connect to the PC through Wi-Fi with power input
requirement of +12 ~ +48 VDC.
The CL-200-WF device can be configured as station mode, such that the PC/Laptop
can be connected through Wi-Fi AP.
The CL-200-WF device can be configured as AP mode, such that the PC/Laptop can be
connected through Wi-Fi directly. Only one device is allowed to be connected to the
DL-300-WF module in AP mode.

3.5 MQTT
MQTT stands for MQ Telemetry Transport, it is a publish/subscribe, extremely simple
and lightweight messaging protocol, designed for constrained devices and
low-bandwidth, high-latency or unreliable networks.
The Publish-Subscribe messaging pattern requires a message broker. The broker is
responsible for distributing messages to interested clients based on the topic of a
message. Now the MQTT Version 3.1.1 becomes an OASIS standard, it is an ideal
protocol for communicating with connected devices in the emerging
"machine-to-machine" (M2M) and "Internet of Things" applications, and for mobile
applications where bandwidth and battery power are at a premium.
Input the IP address and port number for the MQTT broker and click on the Update
Settings button to save the parameters.
The MQTT Last Will and Testament (LWT) feature is used to notify other clients about
an ungracefully disconnected client. A CL-200-E can register an offline message (LWT)
to the broker. The LWT message will be deliver to all clients who subscribe to the offline
topic if the CL-200-E disconnects unexpectedly.
CL-200 Series User Manual Version 1.2.0 Apr. 2019 - 42 -

- Cycle: sets the time period for update the publish messages in millisecond.
- Module Topic Name: sets the module topic name.
- PM2.5/CO/CO2/NH3/H2S/HCHO/TVOC/Relative Humidity/Temperature (°C)/
Temperature (°F)/ Dew Point (°C)/ Dew Point (°F) Sub Topic Name: sets the sub topic
name for each item.
A MQTT client subscribes the messages form a MQTT broker by specifying the topic
name as
Module Topic Name + Sub Topic Name
For example, to subscribe the CO2 level in this case, a MQTT client subscribes the
topic name from a MQTT broker as
EtherIO/CO2
If a MQTT control message is published to topic name: “Module Topic Name + DO0 Sub
Topic Name ” for a CL-200 logger, the logger will follow the MQTT message described
to set the Relay Output.

3.6 I/O Settings
Users can change the temperature unit to Fahrenheit or Celsius in this field.
To Enable/Disable the CO2 Automatic Baseline Correction function.
Q & A
Q: What is ABC (Automatic Baseline Correction)?
A: ABC stands for the Automatic Baseline Correction which is used to adjust a shifted
baseline to the carbon dioxide level in fresh air. In case of normal indoor application,
the carbon dioxide level drops to nearly outside air where there are no human, green
plants or anything to elevate the carbon dioxide levels on weekday evenings or
weekends, the ABC algorithm constantly keeps track of the lowest reading and
slowly corrects it as the expected value in fresh air typically around 400 ppm.
Q: Why I need to enable the ABC?
A: When the CO2 concentration detected in a period time of unoccupied space is
greater than the base value of 400ppm, enable the ABC function to adjust the
baseline. Be careful that the ABC will not work if a space is constantly occupied such
as a hospital, 24-hr factory, 24-hr store, green house or other applications where
CO2 levels may be elevated at all times.

8. FAQ
Q1: What is ABC (Automatic Baseline Correction)?
A1: ABC stands for the Automatic Baseline Correction which is used to adjust a shifted
baseline to the carbon dioxide level in fresh air. In case of normal indoor application,
the carbon dioxide level drops to nearly outside air where there are no human,
green plants or anything to elevate the carbon dioxide levels on weekday evenings
or weekends, the ABC algorithm constantly keeps track of the lowest reading and
slowly corrects it as the expected value in fresh air typically around 400 ppm.
Q2: Why I need to enable the ABC?
A2: When the CO2 concentration detected in a period time of unoccupied space is
greater than the base value of 400ppm, enable the ABC function to adjust the
baseline. Be careful that the ABC will not work if a space is constantly occupied
such as a hospital, 24-hr factory, 24-hr store, green house or other applications
where CO2 levels may be elevated at all times.
Q3: Does the CL-202/CL-212/CL-203/CL-213 enable the ABC as the factory default
setting?
A3: No, the ABC is default disabled in a CL-202/CL-212/CL-203/CL-213 logger to
prevent the baseline from being adjusted to an incorrect value in case of using in a
constantly occupied space.
Q4: What to do when the ABC is no work?
A4: When the ABC is no work regarding baseline correction, the
CL-202/CL-212/CL-203/CL-213 needs be returned to ICP DAS.
