=== '''Debug Port Settings''' ===

AOM-3821 can communicate with a host server using serial cables. Common serial communication programs such as HyperTerminal, Tera Term, or PuTTY can be used in this case. The example below describes the serial terminal setup using HyperTerminal on a Windows host:<br/> 1. Connect AOM-3821 with your PC using a serial cable.<br/> 2. Open HyperTerminal on your Windows PC, and select the settings demon�strated in the photo below.<br/> 3. Insert a power adapter into the DC jack and power up the board. The Debug  console log will be displayed on the terminal screen.
