Rietschen's RGB camera switched to 12 bits offers BayerRG12Packed, not
BayerRG12p, and the program took it for an unknown format: from 2026-10-26
11:33 every picture was saved as "legacy", undebayered raw bytes. The two
are not the same format under two names. Both put two pixels in three
bytes, but the GigE Vision 1.x packing carries the first pixel's high bits
in the first byte, where GenICam's 12p carries its low ones; read as 12p
every other pixel is scrambled.
BayerRG12Packed is now a layout of its own, unpacked and sampled for
brightness its own way and de-Bayered like 12p. Checked against the
hardware on rietschen's NIR camera (Mono12Packed, the same packing): the
12-bit frame unpacked this way differs from an 8-bit frame of the same view
by 2.8 on average, unpacked as 12p by 29. The gige recipe prefers
BayerRG12Packed, so a re-export keeps the 12 bits. Tests 544/544 (mock).

configureSettle() read the camera's auto-exposure target, tolerance and
limits before the camera was opened, so it got none of them and judged every
frame against its 50 +- 5 % default until the first profile switch - on
every tower. It now runs again once the camera is open. On the Alviums this
brings their own IntensityControllerTolerance and, at night, the at-limit
verdict from their chunk data into play.
The gige recipe aims at 35 % instead of 50: at 50 the sky over the horizon
burnt out at noon on rietschen, where smoke would rise. The old program ran
these cameras at 23-25. Tests 542/542 (mock).

Rietschen's RGB camera came with ExposureAutoAlg = FitRange and a 10 %
tolerance. FitRange fits the histogram wherever the mean lands, and the
camera stopped adjusting 10 % off its target, so the keep rule's 50 +- 5 %
band was never reached: at a 3 s interval every waypoint ran into its 2 s
frame_timeout (2026-10-21). The gige recipe now sets Mean and 5 %, as the
NIR camera already had. By day the exposure floor goes from 200 to 20 us:
at noon the camera sat at 200-600 us with no room to darken a bright view,
and without chunk data the host cannot tell a camera at its limit from one
still settling.

A free-running Manta runs at AcquisitionFrameRateAbs, not at its limit:
rietschen's RGB camera came set to 0.955 fps and delivered 5 frames in 5.2 s.
The gige recipe now writes a short fixed exposure and then the rate, clamped
to the camera's maximum (4.7 fps at 60 MB/s), before auto-exposure goes back
on. The export summary shows the rate set, not the limit, which had read
4.71 fps for a camera running at 0.96.
test hardware env asked for a DHT11 reading at once, but the firmware reads
it every 10 s, the first time 2 s after it starts. install-tower --verify
failed on rietschen 1.4 s into its run, 36 s after the same test had passed.
It now waits one read period for the first reading. Tests 542/542 (mock).

Rietschen has three Manta G-1236 on one GbE port, whose firmware predates the
names the program uses. A feature missing by its SFNC name is now looked up by
the older one (ExposureTimeAbs, AcquisitionFrameRateAbs, ExposureAutoTarget,
ExposureAutoAdjustTol), so test camera, the telemetry and the keep rule's
reads work. export_camera_profile.py picks a gige recipe for such a camera:
frame trigger off, BayerRG8 or Mono8, 60 MB/s, auto-exposure target 50 %.
At the cameras' old target of 25 every waypoint ran into frame_timeout_ms.
The camera probe now lists every camera. With several, the hardware.ini kit
writes CHOOSE_ONE, install-tower asks which is the colour one, and the profile
export is given that id - the first one the SDK lists was the NIR camera.
install-tower names the unit that holds the motor port instead of assuming
start_gimbal.service.
Tested on rietschen's NIR camera with the motor mocked, beside the running old
program: test camera PASS, a snapshot as a 3008x4112 grey JXL, a scan keeping
a picture every 5 s. Tests 542/542 (mock build). The colour camera is not yet
tested; the old program has it open.
