CLI MANAGEMENT INTERFACE
CLI Access via External Serial Port
To use the CLI management on the XDG you must connect to the RS-232 external management serial
port. Only TX, RX and GND connections are needed for operation. You then must open the serial port in
a terminal program such as: RealTerm, Putty, HyperTerminal, minicom, etc. The COM port must be set
up to run with a baud rate of
115200, 8 data bits, 1 stop bit and no parity
.
Note: the XDG external serial port is compatible with RS-232 Input/Output Levels (NOT TTL or CMOS).

CLI Access via PCIe/104 Bus
The XDG product connects to the CLI management interface via the PCIe/104 bus. This serial port is
generated from on-board PCIe UART the Exar 17V352. Ensure the DIP Switch position 2/B is ON if you
want to access the CLI via the PCIe/104 bus.
Additional drivers will be needed to properly operate the additional serial port.
Drivers for this functionality can be found on Exar’s website here:

CLI Basics
Once opening the COM port attached to the management port, after boot up your terminal output
should look like the output below. The
default login
is
admin
and
password
is
blank(“”). So after
typing admin
hit <ENTER> then hit <ENTER> again to login and “?” will display a list of the available
commands.
Below is a list of common quick CLI commands. For a complete CLI reference please see the documents
described below.
