Hi Allan,

Keith and I tried lamp control this evening, with some problems:

0)  We could turn on the LEDs on the little test board, and they
corresponded to the bit numbers in the nirc2_config_file.  However,
Keith preferred a different ordering, and also to have all four
sequential.  I changed nirc2_config_file after our tests, so that bit 0
is neon, bit 1 = argon, bit 2 = krypton, bit3 = xenon, and bit4 =
keyword LAMPPWR, which is probably not really attached to anything.  I
would delete LAMPPWR from the config file, but I'm not sure whether
that would actually break something.  I might delete it tomorrow.

1)  The keywords readbacks don't represent the state. Initially, with
no LEDs on, everything read 0 except krypton, which read 1.  Turning on
an LED did not change it from 0 to 1.

2)  When we connected up to the lamp control box, which is hooked up to
actual lamps, none of them would turn on.  The device number (7) may
not be correct in the controller.  What is the "ad" command to check
this?

When these issues get resolved, we can retest, and if things are working
we can set the lamps up in front of NIRC2 and Dave and I can proceed at
some point to test the grism.

Thanks,
Bob
