Mini USB Serial Interface
The pfSense SG-4680 has an integrated Silicon Labs' EFM32™ USB Microcontrollers that makes it simple to
access the serial console without the requirement of a null modem cables.
Serial Terminal Emulation Client
A serial terminal emulation program is required to access the pfSense SG-2440 console through the mini USB
serial interface. Microsoft Windows no longer includes
HyperTerminal
in Versions 7 and higher.
PuTTY
is
free and can be downloaded from:

Accessing the Console
Connect a Mini USB cable to port #1 as shown in
Figure 1
on the pfSense SG-2440 and the other to a USB
2.0 port on the computer with a terminal emulation program installed.
Configuring Serial Terminal Emulator
PuTTY
must be configured to communicate with the pfSense SG-2440. In order to do so, you must first
know what Com Port your computer has assigned to your serial port. Even if you assigned your serial port to
COM1 in the BIOS, Windows may remap it to a different COM Port. To determine this, you must open
Windows Device Manager
and view the COM port assignment.
