The KATCP Server receives requests from CAM. These requests may include:
- ?configure
- ?capture-init
- ?capture-start
- ?capture-stop
- ?capture-done
- ?deconfigure
- ?halt
- ?help
- ?log-level
- ?restart [#restartf1]_
- ?client-list
- ?sensor-list
- ?sensor-sampling
- ?sensor-value
- ?watchdog
- ?version-list (only standard in KATCP v5 or later)
- ?request-timeout-hint (pre-standard only if protocol flags indicates timeout hints, supported for KATCP v5.1 or later)
- ?sensor-sampling-clear (non-standard)
The ?configure ?capture-init ?capture-start ?capture-stop ?capture-done ?deconfigure and ?halt requests have custom implementations in katcp_server.py's BLBackendInterface class. The rest are inherited from its superclass. Together, these requests (particularly ?configure) contain important metadata, such as the URLs for the raw voltage data streams from the F-engines. The timing of these requests is important too. For instance, the capture-start request is sent when an observation is about to begin.
