Loading the DBBC2 firmware
- Log into the DBBC2 (user dbbc, password: ask Salvador/Helge); can be done also via remote desktop from mrt-vlbi
- Depending on the observation mode (PFB, or DDC) there are two different firmwares to be loaded:
- Polyphase Filterbank Mode (PFB)
On the desktop double-click: "DBBC2 Control PFB v16..." icon (exact name can vary depending on the version)
- Tunable Mode (DDC)
On the desktop double-click: "DBBC2 Control DDC v105..." icon (exact name can vary depending on the version)
- Reply 'y' to the question whether to configure, wait until the configuration is finished. During the process the LEDs on the DBBC2 frontside will change. Leave the window open after the configuration is finished.
- Note: in case the USB cable from the DBBC2 is still plugged into the FiLA10G loading of the firmware will throw an error. Make sure the cable is unplugged!
Loading the FiLA10G firmware
- Connect the USB cable from the backside of the DBBC2 (top right connector) to the FiLA10G box
- On the Desktop of the DBBC2 double-click the FiLA10G icon
- Verify that loading of the firmware did not throw errors
- Verify that the LEDs on the frontside of the FiLA10G box are operating (left LED should be red, middle one should be blinking green every 10s)
