Unicore UM980
Budget (wireless) ELT0233 stations can be updated more easily using the receiver manufacturer’s instructions and the UPrecise utility via the receiver’s front-panel USB port. It’s recommended to stop the main service during the update process. Advanced (wired) ELT0231 stations must be updated strictly according to this guide.
Set the receiver speed to 460800, as described in the “Changing the Speed” section.
Enable the “Rtcm tcp service” and temporarily disable all other services except for “Main service” and “Rtcm tcp service” while updating the firmware.
Setting Up VSPE
You will now need a Windows program that converts TCP/IP to a COM port. Several such programs are available; we’ll describe Virtual Serial Ports Emulator (VSPE) as it is the most versatile. Download and install VSPE from the “Eterlogic Software” website.
It is recommended to install the “Virtual Serial Ports Emulator for 32-bit Windows operating systems” version because it does not require a license and can be used for free. However, if you have 64-bit Windows, you can use VSPE with the built-in Evaluating license. Details are available via the provided link
After installation, launch VSPE. Click the “Create new device...” button.
Create a Virtual Pair
Select “Virtual pair” and click Next.
On the next screen, you can change the COM port numbers or keep the defaults selected by VSPE. Then click the Finish button.
Now you’ll see that a COM port pair has been created. Click the “Create new device...” button again.
Create TCP Client
Select “TCP Client” and click Next.
Set the IP address (usually rtkbase.local) and port (typically 5016). Click the “Settings...” button.
Change the speed to 460800, then click OK, and finally click Finish.
You should now see a result similar to this:
Running UPrecise
Download and launch UPrecise from the website. At the bottom, enter COM2 (the second port of the created pair) and the speed 460800, then click the “Connect” button.
On the left panel, click the “Receiver Upgrade” button.
After clicking the button, the firmware update settings window will appear. Check the box next to “Receiver 1”. Select “Soft Reset”. Click “Select upgrade file” and choose the new firmware file.
Once the new firmware file is selected, click the Start button. The firmware update process will begin.
After the update is complete, you will see a message like this:
Final Steps
Close both UPrecise and VSPE. Then perform “Detection” and “Configuration” as described in the corresponding sections.
