Keysight U3810 Series Getting Started Guide

Establish Serial Communications between BeagleBone and PC

If not already done so, download and install PuTTY from

http://www.putty.org/

Choose 32-bit or

64-bit, whichever is compatible with your operating system.

Only connect a USB cable from your computer to J15 of the U3810A. The JP1 should be in place
and JP55 should not be placed.
