Firmware update using support software
C1-FS receiver firmware upgrade is done on Windows PC. The connection method can be selected from the serial port of the receiver and Ethernet. I have already set an IP address on the receiver, so I chose an Ethernet connection.
Start BY_Connect on your computer and click the gear icon to open the connection method selection window.
Here, press the
Add Row button, enter TCP Client in Type, host name and IP address in Input_1, port number in Inpu_2, and save. Then, when I clicked Open in the Done column, I was able to connect to the C1-FS receiver.
Firmware Upgrade from the
Tool menu, click the Select button in File Path, and select the firmware file
firmware_C1_7.69_20220505_B3F105_release.dat. We can select the amount of delay for firmware transmission in milliseconds, but since it is over the network, I left it at the default value of 1 ms.
And finally hit the Update button. If the firmware update fails, it will be just a box, so I am always nervous when updating the firmware.
The lower part of the update window (yellow background) changes in the order of
Upgrade success, please reboot. and the firmware update was successful.
We can see the receiver status by opening Board Config in the BY_Connect Tool.
The documentation on interface protocols and commands hasn’t been updated since the previous firmware, so it seems mostly bugfixes.
Earlier, when I checked the C1-FS receiver’s web interface, I felt it wasn’t very informative. When I checked this time, the menu screen worked. Username and password are the same as before.
Upon further checking, it did not work on Macintosh browsers (I checked with Safari and Firefox), but worked with Windows browsers (I checked with Edge and Firefox). I’ll try it again on Linux. It seems strange that the behavior depends on the OS, not the type of browser.
