Firmware RRC-1258


To download the new firmware click on the blue link. Instructions about how to update the firmware is described under Common configs and Start up settings pages.

Note that the firmware is the same for both RRC-1258MkII and the earlier version 1.

Remember that the .zip files must be unzipped before upoaded to the RRC.

The RRC:s can be upgraded with the Microbit Setup manager (via USB) or via the built in Webserver which means that it can be done remotely over the Internet.

Instructions how to do it via the Setup Manager  is available on the Setup Manager page.

Important! If you are upgrading a radio RRC from firmware version 2.85 or older then all control RRCs used to connect to it also must be upgraded!

Application upgrade

The Software can be updated over the internet via the web interface when bugs are fixed and/or new functionality is implemented. You don’t have to be where the RRC-1258MkII is to do the updates.

First: Download the new firmware from www.remoterig.com and save the file on your computer. Unzip it to your desktop. It will have a name like RRC1258-CRC_v2.34_2011-02-14.bin

Start your web browser and connect to the RRC you want to update. Click on the link ‘Application upgrade’ to the left. Click on the ‘Browse’ button and select the file you downloaded a minute ago. When you have found it click on ‘Upgrade’. The new firmware is transferred to the RRC and is written into the flash memory of the RRC. The RRC will now restart, Note: Do not interrupt the upgrade process in any way.


Wait a minute or two then connect to the RRC again and click on the “Info” link to the left and check that the Software version is updated. If it looks like it’s not updated empty the web browser cache, to prevent it from showing an old cached page. The update NEVER fails but the browser is a common problem.
