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.

8.3

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

h

M:addr

[

-addr

]i

Read DSP mem

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

>

diag wm

h

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.
