sound 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]iWrite 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.
8.3Diagnostic 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 hnloopiRead 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
rm reads the P:, X:, or Y: memory of the DSP chip. All in hex (alas?).
diag wm M:Xaddr XvaliWrite DSP mem
rm wr tes values to the P:, X:, or Y: memory of the DSP chip. Also in hex (also alas?).
diag ii |
iirein tializes the I/O with the parallel interface and
diag ic iIn t 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 hcmdiIssue 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.
