How to change IP address of UST-10/20LX ?
Can I use ip address changer for UTM-30LX-EW ?
You seem to have CSS turned off.
Please don't fill out this field.
You can use UrgBenri for that. It is also possible to use ip address changer. However once you change the default IP address, it is not possible to use ip address changer to change it back to default. For that you can use UrgBenri or hard IP reset.
Could you please explain how to use URGberni to change the IP addres??
There are a few points regarding changing the UST-10LX/20LX IP address. If you are familiar with IP addresses goto to number 2.
1). Your computer network configuration matches that of the sensor
Sorry to start with the obvious first but as you may already know, in order to connect to the sensor there must be a route between the computer and the sensor. Either the computer is in the same local network as the sensor (there are no routers) or the computer is behind some router which is correctly configured. I will explain here only the local network situation.
Your computer has to be configured to be in the same network address of your sensor and cannot have the same IP address of the sensor. The sensor's default (factory) IP settings are:
IP address: 192.168.0.10
Network mask: 255.255.255.0
Remember that the network address is the AND operation between the IP address and the network mask
192.168.0.10 AND 255.255.255.0 = 192.168.0.0
If your computer is configured to be in the same network address, with the same network mask and host part is not 0, not 255 and not equal to the sensor IP address, you will be able to connect without any problems.
If the sensor is currently configured with 192.168.0.10/255.255.255.0 and you want to configured with 10.0.0.22/255.0.0.0, your computer has to be prepared beforehand so to be in the network address 192.168.0.0 (for example 192.168.0.15). After you change the IP address and to test the new setting you must have a computer (maybe the same one) prepared in the new network address 10.0.0.0 (for example 10.0.0.123). Several OS (Windows Linux, MACOS) allow you to configure several IP addresses for the same network device. You can test your settings all in the same computer.
2). You know the current IP address of the sensor
Provided that you can connect to the sensor, you can use URGBenri Standard (not the lite version), go to the Ethernet tab and to the bottom you'll find the "Change IP Address" button. See the attached picture.
You just need to type the new IP address, network mask and gateway address, and press the change button. URGBenri will ask you if you want to reconnect to the sensor with the new IP address, if your computer is already configured to match the new network address of the sensor then reconnection will work correctly.
3). You don't know/forgot the current IP address of the sensor
The sensor has an external input signal to reset the sensor's IP address to the factory default (192.168.0.10, mask 255.255.255.0, gateway 192.168.0.1). Please consult the hardware manual of the sensor for details.
If you cannot use the external input signal there are two options to recover the current IP address.
a. Use the same URGBenri Standard to find the IP address, use the "IP Address lookup" tool to discover the IP address. Please be aware this process can take a potential long time.
b. Use Wireshark: with the sensor powered on and its Ethernet cable disconnected from the computer, use the Wireshark "arp.isgratuitous" filter, then plug the Ethernet cable into the computer. The sensor sends an Gratuitous ARP broadcast message with its current IP address and Wireshark with record it. If this fails, try unplugging and plugging again the Ethernet cable.
4). You can connect to the sensor OK but fail to configure the IP address.
There is an issue with the firmware of UST-10LX/20LX up to version 2.19 with does not allow configuring subnetting/supernetting. Just in case explaining is necessary, for example for Class C network address 192.168.0.0/255.255.255.0, subnetting means a mask modified so to have less bits for the host part (for example 255.255.255.192 to have 6 bits for host); supernetting on the other hand means a mask modified to have more bits for the host part (for example 255.255.240.0 to have 12 bits for host).
To solve this issue, please update the UST-10LX/20LX firmware, the latest version is 2.21 and you can find it here:
You will need to download the "Update Tool" first and then the corresponding firmware file for your sensor. Please read the README-en.txt file of the update tool for details how to change the sensor firmware.
Hope this long explanation sheds some light.
