Procedure:

1) Plug the PAM device into the computer. Ensure that the USB side of the cable is 
connected to a USB port in the computer and the USB C side of the cable is 
plugged into the PAM. Turn on the PAM device by pressing the circular button on 
the side of the device. 

2) Open the TeraTerm application on the computer.

3) Select ‘OK’ if the Tera Term: Error message appears. 

4) Locate the menu options on the top of the TeraTerm screen. Go to File-> New 
Connection. A new screen should appear on top of the TeraTerm screen. Locate 
the ‘Serial’ section at the bottom of the pop up. Make sure that the connection is 
set to serial. This is indicated by the black circle to the left of the word “serial”.

5) Locate the port dropdown menu. Set the COM port to the one that has the words 
`Silicon Labs’. This indicates that the port is the one connected to the PAM. In 
this example, COM 17 contains the words ‘Silicon Labs’ so it is the selected port. 
Once done, select ‘OK’ at the bottom of the screen.

6) Go to Setup->Serial Port. Locate the ‘Baud rate’ section of the setup menu. Open 
up the dropdown menu. A list of baud rates will appear. Set the baud rate to 
115200. This is the baud rate that the PAM devices connect to. 

7) Once the baud rate is set, select ‘OK’ on the right hand side of the screen. The 
PAM device should connect to TeraTerm and begin outputting data. 

8) In TeraTerm, type the letter ‘m’. This will open the serial menu which contains a 
series of settings that can be changed. Press ‘?’ and press enter to open a list of 
all actions in the menu. 

9) In the menu, type ‘g’ and press enter. If wifi is disabled on the PAM, doing this 
will enable it. If wifi is enabled on the PAM, doing this will disable it. Make sure 
that wifi is enabled. 

10) In the menu, type ‘h’. This will open the wifi credentials setting. This changes 
the wifi network that the PAM device is connected to. A question will appear 
asking “Are you sure you would like to change the wifi credentials?”. Type ‘y’
and press enter. 

11) A list of available networks will appear. Type the number in front of the desired 
network in the menu to select a network and press enter. 

12) A prompt will appear asking for the password to the wifi. Enter the wifi 
password and press enter. 

13) If done correctly a message will appear saying “Successfully connected to the 
wifi network!”

14) If the PAM doesn’t successfully connect to wifi, retry the steps and ensure that 
all information is entered correctly.
