5. Environmental requirements: Operating temperature –10°C to 60°C; storage temperature –40°C to 85°C; relative humidity 5% to 95% (no condensation).
6. Keep out of direct sunlight, away from heat sources or areas with strong electromagnetic interference.
7. Check that required cables and connectors are installed.

2.2 Equipment installation method

This series of products also adopts wall-mounted installation method

2.3 Install ground protection

3. Step 1: Loosen the ground nut.
4. Step 2: Put the grounding ring of the cabinet grounding cable on the grounding post.
5. Step 3: Tighten the ground nut.

Note: Ground the device to improve its immunity to interference. Depending on the environment of use, connect the ground wire to the grounding post of the device.

Figure2-3

3. Operation Instructions

3.1 System Upgrade

The OTA upgrade package needs to be obtained from Inhantong technical support.

Method 1. Upgrade via USB disk:

Place the image file to be upgraded (the file name must be update.img) in the root directory of the USB flash drive, insert the device and enter the Recovery mode (refer to the 3.10 MODE button section), select <apply update from udisk> and perform subsequent operations, as shown in the figure 3-1. This method is mainly used when the system firmware is too large or the Debian system cannot be started.

Figure3-1

Method 2: Upgrade via command:

Push the firmware to be upgraded (the file name must be update.img) into the /userdata directory and use the "update ota" command to upgrade.

Note that when the ota package is larger than the userdata partition, it needs to be updated through udisk. Backing up a Debian system takes up a lot of space, which reduces the user's available space.

3.2 Display Setting

3.2.1 Screen Rotation Settings

The InBOX 700 series is capable of self-adaption of screen resolution, and the screen resolution can be modified. The modification method is as follows:

Click on the icon  in the lower left corner of the desktop, click "Preferences >> Monitoring settings", open the resolution setting dialog box "Display Setting", and select the corresponding resolution according to your own screen, as shown in Figure 3-2-1-1.

Figure 3-2-1-1

When the resolution is selected, click the <Apply> button to pop up the confirmation dialog box, and click <OK>, as shown at Mark 1 in Figure 3-2-1-2. Finally, click <Save>, as shown at Mark 2 in Figure 3-2-1-2, to complete the setting.

Figure 3-2-1-2

3.3 Ethernet Settings

3.3.1 Ethernet parameter setting

InBOX 700 Ethernet does not support graphical interface configuration, which needs to be modified and confirmed by command configuration. View through "cat /etc/network/interfaces". The default address is 192.168.2.2, as shown in Figure 3-3-1.

Make modifications through command "vi /etc/network/interfaces".

View command : cat /etc/network/interfaces

As shown in Figure 2-2-1, the current address of this machine is 192.168.2.2 (default)

Figure 3-3-1

You can modify the configuration file directly to modify the IP.

Modify command: vi /etc/network/interfaces 

Specific VI commands are not repeated here.

3.3.2 Enable WAN port

NOTE The introduction to "enable WAN port" function is only applicable to InBOX710-DS、InBOX730.

The InBOX 710-DS、InBOX730device contains two network ports, both of which are LANs by default. If you need to switch one of them to WAN, you need the following configuration:

Switch LAN1 to WAN:

2. Use the sudo-s command to get root permission;
3. Use the following command step by step

systemctl unmask ih_vlan

systemctl enable ih_vlan

3. You need to restart to make the configuration take effect, and you can use the reboot command to restart;

Restoration step (switch WAN back to LAN1):

2. Restore the configuration through the systemctl mask ih_vlan command;
3. You need to restart to make the configuration take effect, and you can use the "reboot" command to restart;

3.3.3 ConfigureWAN port

NOTE The introduction to "Configure WAN port" function is only applicable to InBOX710-DS、InBOX730.

1．If your device is InBOX710-DS

After switching LAN1 to a WAN port, you need to configure the IP.

WAN interface: wan0 and LAN2 interfaces: Lan0

ifconfig wan0 <specify ip> netmask <specify mask>//set IP and mask 
route add default gw <specify gateway>//set gateway

2． If your device is InBOX730, you can refer to the following configuration to modify the /etc/network/interfaces file.

auto eth0

iface eth0 inet manual

auto wan0

iface wan0 inet static

address 192.168.10.2

netmask 255.255.255.0

gateway 192.168.10.1

dns-nameserver 192.168.10.1 8.8.8.8

vlan-raw-device eth0

auto lan0

iface lan0 inet static

address 192.168.2.2

netmask 255.255.255.0

vlan-raw-device eth0

3.4 Wi-Fi Settings

Make sure the Wi-Fi antenna is connected before enabling WLAN interface.

Right-click on the red circle  at the bottom right of the desktop, select <Enable Wi-Fi>, and turn on WiFi, as shown in Figure 3-4-1.

Figure 3-4-1

Left-click on the same location to display the WIFI list. The SSID and security settings (open network or WPA/WPA2 protection) of surrounding WiFi networks will be automatically scanned in the WiFi list, and one of the WiFi networks will be selected for connection. When encrypted network is selected, the password input dialog box will pop up automatically. Enter the password and click Connect. As shown in Figure3-4-2.

Figure 3-4-2

3.5 4G Settings

The InBOX 700 series supports automatic matching with APN and dial-up networking. At the same time, some parameters of Debian version can be modified to meet various customer needs.

Before using the function, you need to use the "sudo-s" command to get root permission.

3.5.1 APN Settings

If your SIM card cannot access the Internet through automatic dial-up, you need to set the APN:

nvram set wan1_ppp_apn=vzwinternet //Set the apn of SIM card 1

nvram unset wan1_ppp_apn //apn is not set

InBOX 710-DS needs to configure SIM2:

nvram set wan1_ppp_sim2_apn=vzwinternet //Set the apn of SIM card 2

nvram unset wan1_ppp_sim2_apn //apn is not set

3.5.2 Device restart dialing setting

When a total of 30 dialing failures occur, the device automatically resets the modem to try to recover from the failure. You can also modify it through the following command.

nvram set max_ppp_redial=30 

When a total of 120 registered network failures occur, the device will automatically restart the dial-up service to try to recover from the failure. You can also modify it through the following command. 

nvram set max_modem_reset=120 

3.5.3 Enable or disable dual card function

The introduction to "enable/disable dual card" function is only applicable to InBOX 710-DS. The dual card of the equipment is not enabled by default, so you need to enable it manually.

nvram set dual_sim_enable=1 //Enable dual card function

nvram set dual_sim_enable=0 //Disable dual card function

nvram get dual_sim_enable 

Priority SIM card can be set:

When the device starts (the dial-up service is restarted after failure for 120 times), it will detect the currently set priority SIM card and switch to the designated card first;

nvram set dual_sim_main=0 //specify sim1 

nvram set dual_sim_main=1 //specify sim2 

nvram get dual_sim_main 

Trigger condition of dual card switching: maximum number of network registration retries

When the SIM card connection fails for 5 times, it will automatically switch to SIM2 and dial up for networking. You can modify it through the following command.

nvram set dual_sim_max_retry=5 //Set the number of retries specified

nvram get dual_sim_max_retry 

3.6 Bluetooth connection

InBOX710-DS and InBOX712 support Bluetooth connection as follows:

Click the icon in the lower left corner of the desktop, click "Preferences>>Bluetooth Manager", open the Bluetooth connection interface "Bluetooth Devices", and click <Search> to search for nearby Bluetooth devices, as shown at Mark 1 in Figure 3-6-1.
