Verifying the Integration with a Host System
The following descriptions are applicable for Unex software package only.
11.1.1.
Windows 10/11
For verifying the integration of a SOM-352 with a Windows host system, please follow
the steps below:
1
Install SOM-352 into a mini PCIe slot on a Windows host computer.
2
Check if a network adapter named “ Remote NDIS Compatible Device ” can be
found in Device Manager.
3
Open Command Prompt on the Windows host.
4
Ping the RNDIS device IP of SOM-352 and check if it is alive.
C:\Users\user> ping 192.168.1.3
5
Open a SSH terminal to SOM-352 and check if it works.
C:\Users\user> ssh-keygen -R 192.168.1.3 & ssh root@192.168.1.3
For most Windows 10/11 systems, the RNDIS host driver is installed by default. The
Windows host will assign a default IP
192.168.1.1
to this new RNDIS network adapter. This
default host IP address is configured in
/etc/network/udhcpd.conf
on the SOM-352
filesystem and can be modified if needed.
