G Mode Default Settings
The GPIB-SCSI-A defaults to never asserting SRQ. Use the
srqen
command to configure the GPIB-SCSI-A to assert SRQ under certain
conditions. Refer to
srqen
in Chapter 7, G Mode Functions, for an
explanation of these conditions.
G Mode Functions
The GPIB-SCSI-A G mode functions are divided into four groups–SCSI
functions, SCSI Configuration functions, GPIB Configuration functions,
and General Use functions.
The following G mode function tables contain the programming messages
that are sent to the GPIB-SCSI-A from a GPIB Talker to configure the
GPIB-SCSI-A.
Note:
Boldface letters contained within each function indicate the
abbreviated form that you can use for that function.
