Micro-Node RTCM Information Page

The information presented here is to help users of the Micro-Node RTCM product. The company has shutdown and no longer has a web page and it is unclear at this time whether they will proceed in business. I have copied all of the pertinent links and their content just in case they disappear in the future. While it is unlikely since most of this stuff is a decade old please use the links as a first check as they may be updated from the data I have copied.

Original link to this info - RTCM Firmware Upgrading

The RTCM tries to update it's firmware every time it boots as part of the bootloader process. The bootloader has it's own IP address which is set by menu 14 of the IP parameters menu. The default bootloader IP address is 192.168.1.11. If that address fits in your network you can leave it there for all the RTCMs on your LAN as it is active only during the bootloader process.

If you are updating an RTCM which is behind a firewall you will need to port forward 16388 UDP to the bootloader IP address. If you leave all your bootloaders on the same IP address then you won't have to change the forwarding to update different RTCMs.

The RTCM firmware is updated with a Windows program EBLEX C3 Programmer. Download from here. Put both the exe and the ini file in a folder.

Download the firmware here. You probably want Voter-SMT.cry unless you built a thru-hole board or you need the dspbew version. Save the cry file in the folder with the exe and ini files.

Run the EBLEX Programmer:

• Fill in the target IP address with the public IP if your RTCM is behind a firewall otherwise fill in the target IP address with the bootloader IP address.
• Load the cry file.
• Click the Capture Target button.
• Reboot the RTCM with telnet, power cycle or the reset button. In a moment you should see text come up on the programmer.
• Click the Program button.
• In a few minutes you will see some more messages including a program complete message.
• Click the Reset LIA button. The RTCM will restart with the new firmware.

Telnet into your RTCM and verify the new version is loaded with menu 98.

Additional Notes from users who did firmware updates

From Doug Kingston...

It includes a link to the bootloader package (you'll need a Windows system).

The procedure is not 100% clear on what you do with the bootloader address. You should set the BootLoader IP address to a valid address on the network the device is on when it is flashed. Normally this will be its currently assigned IP address. This is needed because the bootloader is too stupid to do DHCP.

The bootloader works as follows:

• You set the address of the target (dotted-quad).
• You select a firmware image
• You tell it to capture the target.
• [...at this point it starts sending a packet each second to the target waiting for a reply]
• You log into the target and reboot.
• If you are lucky, the bootloader packet will be received during the small window in the reboot process where it listens for them.
• You may need to reboot a couple of times before it actually gets captured.
• You tell it to upgrade, and then reboot the device from the bootloader and you are good to go.
