LedOK Configuration Network
There are three ways for the control card to access the network, namely, network cable
access, WiFi access, 3G/4G network access, and different types of control cards can
choose the network access method according to the application (choose one of the
three).
Method 1: Wired network configuration
Then open the network configuration interface, the first is the wired network, you can
set the IP parameters of the selected control card.
Control card access network priority wire network.
When selecting wireless WiFi or 4G network access, the wired network must be
unplugged, and the IP address of the sending card is obtained automatically.

Method 2: WiFi enabled
Check WiFi Enable and wait for about 3 seconds, click Scan WiFi to scan available WiFi
nearby, select the WiFi and enter the password, click Save to save the WiFi configuration
to the control card.
After about 3 minutes, the control card will automatically search for the WiFi hotspot
connected to the configuration, and the "internet" light on the control card will flash
uniformly and slowly, indicating that it has connected to the cloud platform. At this time,
you can log in to the cloud platform www.m2mled.net to send the program.
Tips
If the WiFi cannot go online, you can troubleshoot the following situations:
1. Check whether the WiFi antenna is tightened;
www.sysolution.net 12

2. Please check if the WiFi password is correct;
3. Check whether the number of router access terminals has reached the upper limit;
4. Whether the E-card code is in the wifi location;
5. Re-select a WiFi hotspot to configure the connection;
6. Is the Y/M series wired network unplugged (priority wired network).
Method 3: 4G configuration
Check Enable 4G, the country code MMC can be automatically matched by the Get
Status button, and then select "Operator" to get the corresponding APN information, if
the operator cannot be found, you can check the "Custom" checkbox, Then manually
enter the APN information.
After setting the 4G parameters, wait for about 5 minutes for the control card to
www.sysolution.net 13

automatically dial the 3G/4G network to access the network; observe the "internet" light
of the control card flashing uniformly and slowly, which means that the cloud platform
has been connected, and you can log in to the cloud platform at this time.
www.ledaips.com to send programs.
Tips
If 4G cannot go online, you can check the following situations:
1. Check whether the 4Gantenna is tightened;
2. Is the Y series wired network unplugged (priority wired network);
3. Check whether the APN is correct (you can consult the operator);
4. Whether the status of the control card is normal, and whether the available flow of
the control card in the current month is greater than 0M;
5. Check whether the 4G signal strength is above 13, and the 3G/4G signal strength
can be obtained through "Network Status Detection".
