sound
hi
Toggle fancy sounds
Qcdcom will use distinctive sounds for various operations. If you don’t want to listen
to them you can turn them off with the sound command.
>
synch
hi
“Ping” the DSP by sending it data and asking it to send it back. This is useful
to check to see whether the controller is alive and receiving commands properly from
qcdcom, or if the electronics may need a hardware reset.

wf
h[
file
]i
Write FITS file
Qcdcom reads out the array into memory, and maintains the image there. The wf
command puts together a FITS header for the image and writes it to a disk file. If the
write fails (for example because the disk is full) wf will abort, but the program will keep
the data in memory and you can save your data after rectifying the problem that prevented
the write.

Diagnostic commands
These commands are for diagnostic purposes only, and should not be used for normal observing.
They include commands to test the data link and provide direct access to the DSP computer.

hall
h
nloop
i
Read Hall sensors
read the Hall effect sensors nloop times. The filter wheel 1 sensor is displayed, and
depending on the position of the switch, either the pupil or filter wheel 2 sensor. This is
useful when adusting the offset level of the amplifiers between warm and cold conditions
to get the sensors within the range of the A/D’s.

diag rm

Read DSP mem
rm reads the P:, X:, or Y: memory of the DSP chip. All in hex (alas?).

diag wm

M:Xaddr Xval
i
Write DSP mem
rm writes values to the P:, X:, or Y: memory of the DSP chip. Also in hex (also
alas?).

diag ii
hi
Re-init I/O
ii reinitializes the I/O with the parallel interface and fiber-optics parallel interface
electronics.
>
diag ic
hi
Init camera
ic instructs the DSP cpu to reload its memory from ROM. This has the effect of
destroying any downloaded code and replacing it with the basic monitor program which
has code for a different detector.
>
diag oc
h
cmd
i
Issue a command to the DSP interpreter
oc sends a three letter mnemonic command to the DSP cpu. Most of the useful
commands are sent by various qcdcom commands automatically, but some commands
can only be sent via oc.
