1Preface
1.1 Purpose of the Manual
This manual supports user during the installation and configuring of the CR5201B/SE5201B Industrial Device Server
Series. It explains the technical features available with the product. For example, it contains some advanced
network management knowledge, instructions, examples, guidelines, and general theories to assist user’s device
management in both hardware and software. A background in general theory is necessary when reading it. Please
refer to the Glossary for technical terms and abbreviations (if any).
1.2 Who Should Use This User Manual
This manual is to be used by any qualified network personnel or support technicians who are familiar with network
operations.It might be useful for system programmers or network planners as well. This manual also provides
helpful and handy information for the first-time users. For any problems on this manual, please contact your local
distributor. If they are unable to assist you, please redirect your inquiries to www.atop.com.tw or
www.atoponline.com.
1.3 Supported Platform
This manual is designed for CR5201B/SE5201B Low-Power Gateway only.
1.4 Manufacturers’ FCC Declaration of Conformity Statement

2Introduction
2.1 Overview
The CR5201B/SE5201B is a Low-Power Wide-Area NB-IoT/Cat. M1/LTE Cat.1 Gateway, which acts as a gateway
for communications between Ethernet (TCP/UDP) port, and SE5201B also has built-in RS-232/ RS-485 port.
The information conveyed by the SE5201B model is transparent to both host computers (Ethernet) and serial
devices (RS-232/ RS-485). Data coming from the Ethernet port is sent to the designated RS-232/ RS-485 port, and
data received from RS-232/ RS-485 port is sent to the Ethernet port, allowing full-duplex and bi-directional
communication. In the computer-aided manufacturing or industrial automation areas, field devices can directly
connect to an Ethernet network via the SE5201B model. In normal PCs or laptops, a virtual COM port can be created
using our virtual COM software to fetch serial data from SE5201B remotely over Ethernet. Note that SE5201B model
does not support RS-422 and 4-wired RS-485. With the SE5201B model, it is possible to communicate with a remote
serial device over the LAN or even over the Internet, which dramatically increases reachability and scalability.
Figure 2.1 illustrates an example of multiple charging piles connected to the SE5201B.
The SE5201B can simplify the process of transforming legacy lighting systems into electric car charging piles.
Serval Charging piles connect to the SE5201B via Ethernet interface, and a monitored device reports to SE5201B
via RS-232/ RS-485 interface. The SE5201B provides low-power, reliable, and secure connectivity so that the device
data can be sent to the control center for remote monitoring and control.

4Configuration and Setup
It is strongly recommended for the user to first set network parameters through Device Management Utility© first.
Other device-specific configurations can later be carried out via Atop’s user-friendly Web-Interface.
4.1 Configuration of Network Parameters through Device Management Utility
Please install Atop’s configuration utility program called Device Management Utility® that comes with the Product
CD or can be downloaded from our websites (www.atop.com.tw or www.atoponline.com). For more information
on how to install Device Management Utility® , please refer to the manual that comes in the Product CD. After you
start Device Management Utility® , if the CR5201B/SE5201B Low-Power Gateway is already connected to the same
subnet as your PC, the device can be accessed via broadcast packets. Device Management Utility® will
automatically detect your CR5201B/SE5201B device and list it on Device Management Utility® ’s window.
Alternatively, if you did not see your CR5201B/SE5201B device on your network, press “Rescan” icon, a list of
devices, including your CR5201B/SE5201B device currently connected to the network will be shown in the window
of Device Management Utility® as shown in Figure 4.1.
Figure 4.1 List of Device in Device Management Utility
Note:This figure is for illustration purpose only. Actual values/settings may vary between devices.
Sometime the CR5201B/SE5201B device might not be in the same subnet as your PC; therefore, you will have to
use Atop's utility to locate it in your virtual environment. To configure each device, first click to select the desired
CR5201B/SE5201B device (default IP: 10.0.50.100) in the list of Device Management Utility© , and then click
“Configuration →Network…”(or Ctrl+N) menu on Device Management Utility© as shown in Figure 4.2 or click on
the second icon called Network on the menu icon bar, and a pop-up window will appear as shown in Figure 4.3.

You may proceed then to change the IP address to avoid any IP address conflict with other hosts on your LAN or
to connect the device to your existing LAN as shown in Figure 4.3. The system will prompt you for a credential to
authorize the changes. It will ask you for the Username and the Password as shown in Figure 4.4. The default
username is “admin”, while the default password is “default”. After clicking on the Authorize button, a notification
window will pop-up as shown in Figure 4.5 and some device may be restarted. After the device is restarted (for
some model), it will beep twice to indicate that the unit is running normally. Then, the CR5201B/SE5201B device
can be found on a new IP address. It may be listed automatically by the Device Management Utility© or it can be
found by clicking on the “Rescan”icon. Note that if you did not change the IP address but changed other
parameter(s), you may encounter another notification window as shown in Figure 4.6.

4.2 Configuring through Web/CLI Interface
Every CR5201B/SE5201B Low-Power Gateway is equipped with a built-in web server in the firmware. Therefore, the
device can be accessed by using a web browser for configuring by entering the device’s IP address (default value
is 192.168.1.1) in the URL field of your web browser. As shown in Figure 4.7, an authentication will be required and
you will have to enter the username and password for accessing the web interface. The default value for username
and password are “admin” and “default”, respectively. The overview page of the web interface is illustrated as
shown in Figure 4.8. Figure 4.9 lists all the menus and submenus for web configuration. Please see Section 3.4 for
the default values.

Figure 4.9 Memu of Configuring Web Page on SE5201B Low-Power Gateway
Typically, users are more familier to use web interface for configuring the device. It is the most recommended and
the most common method used for CR5201B/SE5201B Low-Power Gateway. Please go to its corresponding
section for a detailed explanation.
A Command Line Interface (CLI) such as Telnet/SSH can also be used to configure SE5201B through a console
port. However, users need to enable the “Account Settings”field, as shown in Figure 4.10. Please refer to System
Setup →Admin Settings in Section 4.13.2 for more details. Then, users can input command in the CLI interface, as
shown in Figure 4.11.
