# Macros to control a dac device server (VME card ICV712)
#
#%CATEGORY% Generic I/O
#
#%DESCRIPTION%
# This macro file allows to define dac channels as motors in SPEC.
# As this is implemented on the macro level not all commands will work.
#
#%EXAMPLE%
#%DL%
#%DT% mv dac1 50 %DD% Sets an output of 50 in the dac1 device server.
# this is converted to dac output depending on the ICV712 settings.
#%DT% ascan dac2 0 10 10 1 %DD%
# (scan dac2 from 0 to 10 in 10 steps and count for 1 second)
#%DT% a2scan dac1 0 20 opti -5 5 10 1 %DD%
# (scan the optical table stepper motor from
# -5 to 5 degrees and scan at the same time the dac1 from 0 to 20 micr.)
