2. Get started
Since the USR-M100 is connected through a TCP/IP network, you may need to know some basic facts about networking in order to
connect the server correctly. Specifications and dimensions are not provided in this manual. Please refer to datasheet for more
information.
2.1. Installation
You can choose whether to plug in the other peripheral ports at this point or do it later depending on the actual location of the device
or level of comfort for performing such operation.
2.1.1. DIN-Rail mounting
The USR-M100 has a unique mechanical design that reduces the amount of time required for installation and removal. In fact,
screwdrivers and other tools are not required for any part of the hardware installation, including mounting the device on a DIN-rail, as
well as connecting the wiring for both communication and I/O signal acquisition. Furthermore, no tools are required to remove the
USR-M100 from a DIN-rail. Removing all of the modules from a DIN-rail is also easy using the latch and release tab.
Position the rear panel of the device directly in front of the DIN-Rail, making sure that the top of the clip hooks over the top of
the DIN-Rail , as shown in Fig.1. Push up the the release tab towards the bottom of the DIN-Rail until the the mounting clip snaps
into place.
Fig. 1 DIN-Rail mounting and wall mounting
If you want to remove the device from DIN-Rail. Pull down the release tab with your finger and then remove the module from the
DIN-Rail.
NOTE: Disconnect all connections, including Ethernet, serial, and power cables, from the device before removing the device
from the DIN rail.

2.1.2. Wall mounting
The wall mounting option provides better shock and vibration resistance than the DIN-Rail vertical mount.
Locate the installation site and place the device against the wall. Use the wall mount plates as a guide to mark the locations of
the screw holes.
Drill two holes over the 4 marked locations on the wall. Insert the wall sinks into the walls.
Insert the screws(M3 size) into the wall sinks then tighten the screw to enhance stability, see the following Fig.1.
2.2. Serial port
The USR-M100 supports 2 serial ports, 1 RS232/485 and 1 RS485, and adopts Spring-type terminal. The serial port pin assignments
are shown in Fig.2. When connecting up Modbus devices via an RS485 network they should be daisy chained together, and a dual
twisted pair cable are recommended.The connections should be kept the same throughout the network: positive to positive, and
negative to negative. These may sometimes be labeled up as A and B. The maximum length of the serial network cannot exceed
1200m regardless of boosters and repeaters.
Fig. 2 USR-M100 interfaces
2.3. I/O interfaces
USR-M100 is equipped with two 11-pin Terminal blocks that are used for I/O interfaces. The pin assignments of terminal block are

2.8. Quick test
USR-M100 has a built-in Web server, which provides a convenient way to access and configure the remote IO module. Users can use
Edge , Firefox or Google browser to access it. This chapter is a quick introduction to the USR-M100 smart IO gateway. It is
recommended that users read this chapter and follow the instructions once for the system, and you will have a basic understanding
of the product. For specific function details and instructions, please refer to the subsequent chapters.
2.8.1. Download the software
Download the setting software from PUSR’s website:
https://www.pusr.com/support/downloads/H7-version-set-up-software.html
https://www.pusr.com/support/downloads/usr-tcp232-test-V13.html
You may find it in the download section under your product page. Run the software when the installation has been completed as
shown in Fig.8 and Fig.9.

It is strongly recommended for the users to set the Network Parameters through configuration tool first. Other device-specific
configurations can later be carried out via user-friendly Web-Interface.
Fig. 8 Windows configuration tool
Fig. 9 Test assistant
2.8.2. Hardware connection
For fast networking of USR-M100 smart RTU, you need to prepare a PC, a router, a network cable, a serial cable, and a DC12V/1A
power supply. The hardware connection is shown in Fig.10. To establish a TCP / IP network all devices must be connected to the same
network either locally or via gateway connections.

Connect the power line with the USR-M100 power input. If the power is properly supplied, the “PWR” LED will show a solid red
color. After the system is ready, the “WORK” LED will blink.
Connect one end of the Ethernet cable to the M100’s 10/100M Ethernet port and the other end of the cable to the same Ethernet
network(same router or switch).
Connect a serial data cable(USB to RS232 or RS485) between the USR-M100 and PC. Screwless push-in type connection for
simple and easy connection.

2.8.3. Network configuration（Step1）
The Broadcast Search function is used to locate all USR-M100 gateways that are connected to the same LAN as your computer. Since
the Broadcast Search function searches by MAC address and not IP address, all M100 connected to the LAN will be located,
regardless of whether or not they are part of the same subnet as the host.
Click Search to search for USR-M100 gateways. When your unit appears in the search results, you can click device to select it and

change the IP type to DHCH, save your change. Wait for 5s and search it again.
Fig. 12 IP network setting
When accessing the M100 gateway through the Web, the IP address of the M100 gateway and the PC must be in the same network
segment. After changing the IP address of the M100 gateway, you can access the Web page of the M100 gateway through browser
and perform related configuration operations on it. The user name and initial password are both "admin".After entering the user name
and password, click "OK" and the server will authenticate. After success, you will enter the main page of the Web server, as shown in
Fig.13.
Fig. 13 The main interface of the Web server
The IP address of the PC must be modified to ensure that it is in the same local area network as the IP of the M100 gateway if you
want to connect M100 to PC directly via a net cable. The default IP address of M100 IO gateway is: 192.168.0.7. Set the PC's IP address
as: 192.168.0.X (X is any valid value from 2 to 253 except 7). The specific Windows system operation page is shown in Fig.14. you can
access the Web page of the USR-M100 gateway through browser as mentioned above.

2.8.4. Data transmission test（Step2 and 3）
You can select an operation mode in socket setting page, but for now we use default parameters to test, i.e TCP server. Now
USR-TCP232-Test works as TCP client, you need configure the server IP and port, that is 172.16.14.73:23 of USR-M100 gateway, the IP
address of PC is 172.16.14.15.
In the serial port setting module, you can configure communication parameters for the serial ports RS485, as shown in the figure
below. When configuring a serial network you need to set the following within each device-Baud rate,Parity,Stop bits,Data bits and
keep serial port parameters consistent in the same network. We now configure the COM Settings to operate as required for the M100
devices. Go to the Uart1 Settings tab for confirming values of parameters.
Fig.15 shows an example of parameters setting to test transparent transmission.

3. Configuration and parameter details
3.1. Web interface
The USR-M100’s user-friendly web configuration tool was designed specifically to make configuration and reconfiguration easy; no
reconfiguration effort is required for the unchanged modules.
Every USR-M100 Industrial IO 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 in the URL field of your web browser. An authentication
will be required and you will have to enter the username (Default value is “admin”) and password (Default value is “admin”) for
accessing the web interface as shown in Fig. 16. This approach (web interface) for configuring your device is the most user-friendly.
Please go to its corresponding section for a detailed explanation.
