Installation

1. To separate the backboard and the detector, rotate the backboard clockwise according to the

direction of the arrow (Pic.1&Pic.2).

2. Use a screwdriver to pry the threading hole on the backboard, and remove the cover of the

threading hole (Pic. 3).

3. Let the cable on the wall go through the threading hole (Pic.4 &Pic.5).

4. Unplug the terminal block from the contact pin (Pic.6).

5. Contact the cable to the terminal block (Pic.11&Pic.12), then tightly lock the mounting screw

(Pic.7).

6. Plug the contacted terminal block back into the contact pin (Pic.8).

7.Aim the dot located in the middle of two arrows on the side of the detector with the vertical lines on

the backboard (Pic.9). Then rotate detector following the „FIX‟ direction until it‟s tight (Pic.10).

The installation is completed

Work Indicator

There is a circle ring of indicator light in the center of the housing. This indicator light is used to show

concentration range of measured value.

This indicator light can be controlled by any of measured values of among PM2.5 or CO2 or TVOC

through RS485 communication command, and change the color of indicator light depending on the

concentration.

Meanwhile, the measured value of the change of indicator light can be selected with one minute

average value or one hour average value of 24 hours average value in the communication

command.

The indicating light is controlled by one minute average value of PM2.5 as factory default.

DIP switches can control the ring of indicator light Open, and Green light keeps ON constantly, and

Turn Off the indicating light. Please see the following details.

Active indicators

There is a light ring in the middle of the shell, which indicates the measuring range of CO2

concentration.

The indicator light can be chosen to be controlled by PM2.5, CO2 or TVOC using the Modbus

RS485 interface, and varies according to its concentration.

The measurement value that changes the indicator light can be the average value of one minute,

one hour or 24 hours in the communication instruction.

Factory Default：The light is controlled by the average PM2.5 measurement value of one minute.

Below is indicator color changes corresponding to the measured arrange:

PM2.5 <35ug/m3Green, 35~75ug/ m3Yellow, >75ug/m3Red

CO2 <600ppm Green, 600~1000ppm Yellow, >1000ppm Red

TVOC <0.25mg/m3 Green, 0.25~0.50mg/m3 Yellow, >0.50mg/m3Red

WIFI Settings

In the side of the MSD, there is a reset button in the

hole under “RESET”.

1. After the MSD is power on, insert a thin rod

(a paper clip or a toothpick, etc.) in the RESET hole,

and long press the RESET button for 6 seconds

2. Open the WLAN function of the mobile device, search "MXCHIP_" at the beginning of hot spots,

then connect it.

Note: researched WIFI hotspot is like MXCHIP_07E711, MXCHIP_ is an invariant format, 07E711

is a unique serial number for a WIFI module. Different WIFI modules have different serial numbers.

It will be shown on the surface of the WIFI module.

3. Use the browser of the mobile device, land the site 10.10.10.1

4. If you need to log into the account,

input User Name：admin，

Password：admin. Then “LOG IN”.

5. At this point, get into the WIFI module Settings interface. We will need to modify the parameters

setting. The majority changes concentrate in ”Wifi Mode Select”, ”Station Mode Setting” and

”Network Setting”.

This interface language is default in Chinese, users can switch to English interface in the upper

right-hand corner.

6. On the right side of the interface, Select "Wifi Mode Select", and in the interface, click and select

“Station Mode”, then “Save”.

7. At this point, the restart module prompts appear in the interface, be careful NOT to click "Yes".

After all the parameters are set, restart the module at all.

If customers are not careful to restart the module, need to start again from step 1.

8. On the right side of the interface, select " Station Mode Setting", and in the interface, click "Scan"

directly, then connect to the hot spots.

9. In the interface, select the hot spot which the device will be connected with, such as "TONGDY_3",

then confirm it. Back to the previous interface, encryption based hot spots can be decided on

whether you need encryption or not. Does not need encryption: Disable; Encryption: Enable.

When you choose to need encryption, you need to key in a password to connect to the hot spots in

the increased option, finally "Save". The same do not restart the module.

10. On the right side of the interface, select "Network Setting", and in the interface, for “protocol”

7/ 12

MSD IAQ Detector -User Manual

V.1805

click and select "TCP Client" and "save". The same do not restart the module.

11. After entering other interface, and then get back to the "Network Setting" interface, shown as the

following figure, in the “remote port” and the “server address”, key in the server information where

the device will upload data, for example, the corresponding parameters of Qlear platform.

Remote Port: 20011

Server Address (IP)：119.254.103.119

12. At this point all the parameter settings are done, restart the module.

13. When the module restarts successfully, there will be the following interface.

14. Set up completed, now you can add equipment, and check data on the corresponding server

site.

RJ45 Communications Configuration Instructions

1. Create virtual serial port

First install USR-VCOM and Modbus Poll on PC.

1.1 USR-K2 network port restore factory settings

Device in the power-off state, hold down the button

"RESET" on the bottom of the device, then power on the device again, after 5 seconds, release the

button. If the RJ45 module is the first configuration, no need to reset.

Open software,in the open interface, click on the “create automatically”.

The software will automatically find the device, select the device demanded, and click on the "next",

then, finally click on the "finish".

9/ 12

MSD IAQ Detector -User Manual

V.1805

At this point, the status bar will show "finish->COM2", and pop up dialog box "A virtual serial port is

created". Remember the "COM2" virtual serial port. In the following step, the device address

settings will need it.

2. Modify the IP and gateway for the PC connection

Only when IP and gateway are in the same frequency band, and are specified parameters, PC can

be connected, and set the USR-K2 port.

Enter PC local connection, in the pop-up "local connection state" get into the "property".

Double click on the “Internet protocol version 4 (TCP/IPv4)” to set the parameters, the specific

parameters are as follows

10 / 12

V.1805

Finally, click the „OK‟ to save the settings.

3. Configure USR-K2 parameters

3.1. USR-K2 network port restore factory settings.

Device in the power-off state, hold down the button "RESET" on the bottom of the device, then

power on the device again, after 5 seconds, release the button.

3.2 In the PC browser change into the "192.168.0.7", on the authentication page, enter the “admin”

for both the user name and password.

3.3 In the interface, mainly set the "Local IP Config" and the "RS232/RS485" two settings.

3.3.1 In the "Local IP Config" interface, IP mode select the "DHCP/Auto IP", and save.
