Test the U-type module functionality  

Use a serial port monitor program to test the device functionality.  

The open source program "PuTTY" (

https://www.putty.org/

) can be used to 

test the device manually.  

6.

 

Before starting the session, configure the “Session” via the “Session” menu and 
setting the following: 

 

Verify the correct COM port is populated in the “Serial line” input box 

 

Manually set “Speed” to 115200 

 

“Connection type” should be set to “Serial” 

 

The Digital U-Type has a boot-up time of ~5 seconds before you can communicate 
with it. It will not respond to the laser enable pin during this time.
