Most of the commands have a short form and a long form. Short forms are written in upper case
characters. The part of the command header written in upper case has to be transmitted so that the
MIDAS can recognize the command. The part of the command written in lower case letters can also
be transmitted. It is only used for better understanding.
In general, queries can be executed in local mode. However, most of the set operations have to be
carried out using remote control operation first (remote mode).
The command tables give information about the allowable operations. An 'x' marked in a column
means:
LS setting or executing is allowed in local mode operation,
LA querying in local mode operation is allowed,
RS setting or executing in remote control mode is allowed,
RA querying in remote control mode is allowed.
7.8.2 General Commands

A Commentary.
*IDN? <ARBITRARY
ASCII RESPONSE
DATA> X X Return of device identification in the format:
<Companyname>, <Model>, 0, <Software-
Version>, i.e., HAEFELY TEST AG, MIDAS, 0,
X.XX
*RST X Sets the standard configuration
*TST? <NR1> X X MIDAS returns a '1' for unavailable or defective
hardware, otherwise a '0'
*OPC? <NR1> X X If all pending operations have been carried out,
then the returned answer is ASCII 31 ('1'). The
MIDAS always returns a '1' because all
commands are processed strictly one after
another.
*OPC X X Sets the OPC bit in the ESR status register to
True. Has no further effect on the MIDAS
*WAI X X Does not affect the MIDAS because all
commands are processed strictly one after
another.
*CLS X X Clears all registers
