VXI-Defined Common ASCII System Commands

These VXI-defined Common ASCII System Commands and Queries are described in the
following sections:

•

DCON?

•

DINF?

•

DLAD?

•

DNUM?

•

DRES?

•

RREG?

•

WREG

You can use these commands and queries to retrieve device information/configuration,
perform a soft reset, and peek/poke a device’s registers.

The

DNUM?

query is used to find out how many devices are in the system. The

DLAD?

query

returns a list of logical addresses for devices in the system.

The

DINF?

query returns static information about a device. The

DCON?

query returns

configuration information about a device.

The

DRES?

query is used to perform a soft-reset sequence on a device.

The

RREG?

query and

WREG

command are used to peek (read from) and poke (write to)

registers on a VXI device.
