# LAN Mode Connection

## 1. OTG dual-mode chassis

OTG dual-mode chassis supports both USB screen projection and network cable screen projection

1. [First set the chassis to USB connection mode](https://doc.some3c.com/panda-manual/pages/Ta8WFt0VjRJp0rhTislN#id-1.usb-connection)
2. Connect the computer host with a USB cable and successfully project the screen
3. <mark style="color:orange;">And use a network cable to connect the chassis to the router, which must be the same router as the computer..</mark>
4. Find \[OTG Settings] in the Panda window

5.Type in the terminal: ipconfig Enter the network gateway address in step 3. Click Add.

6.After completion, click the \[Enable] button. The default port is 5555 and generally does not need to be modified.

7.After clicking "Enable", manually press double-click. (A6/A8 chassis only requires a click)the chassis button

## 2.Serial port software control switching

The chassis connects to the computer via a serial port, and the USB/OTG mode is switched via software.

1.Search and run "RUN" open "devmgmt.msc"

2.After connecting the chassis to the computer via USB cable, locate the corresponding CH340 port in Device Manager, and then connect the corresponding serial port in the software.

{% hint style="info" icon="note" %}
Some chassis do not support serial port software.
{% endhint %}

The serial port software includes functions such as "adjusting fan speed", "setting default boot mode", "USB/OTG switching", and "shutting down/restarting" the chassis.

## 3. Is screen projection in WIFI/OTG mode unstable?

Solution

1. Router problem (it is recommended to replace the enterprise-level router)
2. If too many devices are connected to a router, it may cause signal interference and network instability (it is recommended to build a soft router)
3. If the phone is locked, it may cause wifi disconnection

## 4. What should I do if my mobile phone cannot scan?

Solution

1. Is the router connected to the computer the same as the router connected to your chassis? If not, are the networks between the two routers interoperable? If not, please ask a network professional to check.
2. Is the chassis a dual-cut chassis (supports OTG and USB) or a non-cut chassis (supports OTG only)? If it is an OTG chassis, you need to connect to the Panda in USB mode first. After the connection is successful, click to start port 5555, then manually switch the chassis to OTG mode, and enter the network IP connected to your chassis, such as 192.168.1.1 to 192.168.1.255. After entering, click Add, and then scan. If it is a non-cut chassis, directly enter the network IP and scan.
