DL-300 Data Logger User Manual Version 1.1.0 Aug. 2015 - 1 -

1. Introduction

The DL-300 series is a data logger designed to accurately measure and record the
concentration of carbon monoxide/carbon dioxide in the atmosphere, temperature and
humidity. It can display the real-time data and log the concentration of CO, CO2,
temperature and humidity with a date and time stamp for downloading later. The logging
interval is programmable and up to 450,000 data points can be stored in built-in,
non-volatile memory.

Users can configure a DL-300 module from the touch screen or via a regular web
browser when the module and PC are both connected to the same switch or Ethernet
segment. With free iAir app on users’ iOS or Android phones or tablets, they can get the
real data over a Wi-Fi network anytime and anywhere. The free DL300 Utility is a
convenient software tool to get the real-time data, show run charts and download data
from multiple devices running on Windows platform.

The DL-300 series contains RS-485, Ethernet and PoE communication interfaces, the
most common communication interfaces in industrial network. It supports a wide
operating temperature range of 0 ~ 50°C and easy to be installed by placing on a
horizontal surface such as a desktop, mounted on a DIN-rail, or mounted on the wall.

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 DL-300 module via a
standard web browser to monitor the data and configure the settings without install
any software in the terminal.

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 DL-300 modules over a Wi-Fi network anytime and
anywhere. The iAir App can link to the DL-300 modules by specifying IP addresses
or by searching all the modules connected to the same Ethernet segment.

DL-300 Data Logger User Manual Version 1.1.0 Aug. 2015 - 4 -

Data Logging Software

The DL300 Utility can be used to configure the modules, monitor real-time data and
show the run chart, log alarm events, group DL-300 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
DL-300 series well-integrated into the HMI/SCADA systems.

Alarm

DL-300 series allows users to set high alarm level for CO/CO2/
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 DL-300 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 high level alarm occurs.
.

DL-300 Data Logger User Manual Version 1.1.0 Aug. 2015 - 5 -

Screen Lock

Users can secure a DL-300 module by setting a screen lock via the web interface. If
the lock is set, users need to enter the correct password when they would like to
configure the DL-300 module.

Automatic Baseline Correction

The built-in ABC algorithm makes the CO2 sensor on the DL-302 and DL-303
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 CO

2

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 CO

2

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 DL-300 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.

Support for MQTT protocol

MQTT is a protocol designed for the
efficient exchange of real-time data
with sensor and mobile devices. It
runs over TCP/IP and is in widest
use on the "machine-to-machine"
(M2M) and "Internet of Things"
applications today

2.4 Cabling for Power and Network

Note

y Do not install the DL-300 module near a vent, a ventilation fan or a door where the

air flows faster. Also avoid putting the module on a desktop below the nose and
mouth to prevent incorrect measurement.

y Avoid installing in locations where the temperature is below 0°C or above 50°C.
y Avoid installing in locations near a strong electromagnetic field.

For connecting with a PC or a Android device

The DL-300 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 DL-300
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.

DL-300 Data Logger User Manual Version 1.1.0 Aug. 2015 - 14 -

The iAir App and DL-300 Utility search the logger by broadcast, therefore only the
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-300 Utility. Please contact with your network administrator to make sure the DL-300
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 DL-300 logger can connect to the PC through a RS-485 network with power input
requirement of +12 ~ +48 VDC.
