Configuring the parameters using a Web browser
First you need to connect to the UCW232C over WiFi. The UCW232C has DHCP enabled by default so
your wireless connection should be set to support this:

In this example we use Windows built-in wireless network manager to connect to the adapter:
If you enable “Connect automatically” then you don’t forget to manually re-connect when rebooting the
adapter.

The correct way to change and save parameters:
Update 6/19/2015: If you are having problems changing the parameters then Uuse FirefoxUbrowser
instead of Internet Explorer.
1. Change the particular parameter to the value you need and click the Save button. The text
"Saved. Reboot required for the changes to take effect" should appear at the bottom of the
screen. Wait a few seconds.
2. Now click "Reboot" and wait about 10 seconds. The adapter is now rebooting and re-connecting
to WiFi automatically if you have enabled “Connect automatically” in Windows WiFi Manager.
3. Now refresh the browser page by clicking the refresh icon in your browser (or press F5).
If you are having problems connecting to the adapter over WiFi try and disable your firewall software.
You should now be able to see the changed baud rate and also select other menu links etc. Below are
screenshots of the configuration pages:
