3.2 Using the Command Line Interface (CLI)
Differences between USB, Serial and SSH
USB, Serial and SSH each use different methods of access, but all require a login and will present an
equivalent Command Line Interface after login is complete.
The login prompt will appear as "[0000000] Login: " where 0000000 is the device serial

number.
Any terminal emulator can be used, but Tera Term from the Open Source Development Network is
recommended.
USB access requires connecting the USB port on a laptop or PC to the USB-C port on the radio.
Recommended cable length is 2 meters or less. This is typically the simplest way to connect to the unit
and is the recommended method for CLI operation.
Serial access uses an RS-232/RS-485 serial connection from a PC to the unit's COM port. Maximum
cable length for an IEEE-1613 compliant serial connection is 2 meters. The serial port defaults to
operation as a payload data port, using a pre-configured baud rate (default is 115.2kbps). To temporarily
enter into command line mode on the payload port it is necessary to type the escape sequence "+++".
SSH access uses an Ethernet PC connection to the unit's ETH port. SSH can be connected to the unit
from any network point that has connectivity with the PC, including remotely over the Internet, or using
other networks.
Establishing Communication— SSH
Follow these steps to configure the unit for SSH:
Connect to the unit with a PC that is in the same IP network as the TransNEXT. Launch an SSH
client program (like PuTTY) and connect to the unit using its programmed IP address.
The default IP address for the unit is 192.168.1.1. If you do not know the current IP address of the
unit, follow the serial configuration instructions below, where you can determine the address and
continue configuration, or check with your network administrator.
Login with the user name "admin" and default admin password for this unit.
The SSH connection will confirm with the message:
> You are connected to the TransNEXT SSH Server
