Setup

Please check the First Boot Guide if you setup the eManager for the first time.

Network settings

Ethernet and WiFi configurations can be modified.

In the first tab, Ethernet can be configured as DHCP, as shown in the image below, or as Static, so you can choose the desired IP. By default, it is configured as DHCP.

In the second tab, WiFi can be configured as Access Point or in Station Mode. By default, it is configured as Access Point.

wifi_webadmin

For images prior to release 22.10, go to Legacy Setup.

Modem settings

Configure the APN
Create a network operator filename and fill in the APN name. For example, this command creates the apn.EXAMPLE file.
```
echo 'AT+CGDCONT=1,"IP","operator_apn"' > /etc/ppp/chatscripts/apn.EXAMPLE
```
Assign the apn symbolic link to point to the newly created file:
```
ln -sf /etc/ppp/chatscripts/apn.EXAMPLE /etc/ppp/chatscripts/apn
```
If the APN requires a user and password, you need to edit mobile-auth file to define user and password
```
nano /etc/ppp/peers/mobile-auth
```
Save and exit: Ctrl+X. Confirm save with Y. and point provider to mobile-auth file
```
ln -sf /etc/ppp/peers/mobile-auth /etc/ppp/peers/provider
```
Configure the SIM PIN
If the SIM needs PIN code, create a pin code file with the correct PIN:
```
echo 'AT+CPIN=1234' > /etc/ppp/chatscripts/pin.CODE
```
Assign the pin symbolic link to point to the newly created file:
```
ln -sf /etc/ppp/chatscripts/pin.CODE /etc/ppp/chatscripts/pin
```
If SIM doesn’t require PIN code, assign the pin symbolic link to pin.NONE:
```
ln -sf /etc/ppp/chatscripts/pin.NONE /etc/ppp/chatscripts/pin
```
Start ppp service to connect to mobile network
```
systemctl start ppp@provider.service
```
If you need to connect automatically at each startup, you must enable the service:
```
systemctl enable ppp@provider.service
```
Check the connection status and the assigned IP address
```
ip a | grep ppp0
```

RS232/RS485 configuration

Flash partition safe to system updates

Only available in eManager Pro.

To protect the data against system updates and prevent accidental loss, a 5GB /data partition has been reserved. Therefore, the permanent data we want to keep should go in this partition.
