2.Getting Started
自学linux买什么书好In this chapter, we describe how to configure basic settings for the ioThinx 4530 controller. Connecting to the ioThinx 4530 Controller You will need to use a computer to connect to the ioThinx 4530 controller and to log in through the
command line interface. There are two ways to connect: through the serial console port or through the
Ethernet port. Refer to the ioThinx 4530 Series Hardware Manual to see how to set up the physical
connections.
The default login username and password are:
Username: moxa
Password: moxa
The username and password are the same for all serial console and SSH remote log in actions. Root account login is disabled until you manually create a password for the account. The user moxa is in the sudo group
so that you can operate system level commands with this user using the sudo command. For additional
details, see the Sudo Mechanism section in chapter 5.
ATTENTION
For security reasons, we recommend that you disable the default user account and create your own user
accounts.
Connecting Through the Serial Console
This method is particularly useful when using the computer for the first time. The signal is transmitted over
a direct serial connection so you do not need to know either of its two IP addresses in order to connect to
the ioThinx 4530 controller. To connect through the serial console, configure your PC’s terminal software
using the following settings.
Baudrate 115200 bps
Parity None
Data bits 8
Stop bits    1
Flow control None
Terminal VT100
Below we show how to use the terminal software to connect to the ioThinx 4530 controller in a Linux
environment and in a Windows environment.
