On the Dell device, navigate to “Network and Sharing Center”, and click
“Change adapter Settings”. Here, right click on your Local Area
Connection, click “Properties”, and then select Internet Protocol Version
4. Choose “Obtain an IP address automatically.
2.
Repeat the above on the host computer, but ensure that instead the
option for obtaining an IP address is a manual IP address within the
domain of the local network you’re establishing with DHCP server, such
as 192.168.137.1.
3.
Verify that a connection is established via LAN cable and that both
computers have appropriate drivers installed.
2.
Cannot ping the Dell device from the host
computer / Cannot open a command line on the
Dell Device

Ensure the Dell Device’s Windows Firewall is turned off.

Verify you are logged into the device as the Adminstrator.
3.
Can’t set up a WebSocket connection by
running the “wsems” application.

Try to type “wget YourLaptopIPAddress” to see if you can obtain data
form the server. If not, make sure all Firewalls are disabled on both
computers.
2.
Try changing the system clock on the Dell Device to make it match that
of the host computer’s.
4.
Using the Windows Powershell
“[System.IO.Ports.SerialPort]::getportnames()”
command, I am unable to see any available
port names.
1. Verify that the computer is connected to the Dell Device via serial cable.
2. You may need to manually install or re-install Device Drivers for the
Windows Serial Port.
a. Open Device Manager from Control Panel in Windows.
b. Click on “Ports (COM & LPT)”, and click “Action > Add Hardware /

“luaScriptResource. Error says “rserial is “nil””
2.
Make sure you have modified the port number in “testSample.lua” in
both places in this file so that it matches your Dell device’s port number.
This may or may not be the same number as your connected host
computer’s.
