4.3 Initialization of Devices by ∗RST Command
■ Format
∗RST
■ Application example
WRITE @103:"∗RST"
Only the device at address 3 is initialized at level 3.
■ Explanation
The ∗RST(Reset) command, an IEEE 488.2 common command, is used to reset a
specified device at level 3.
Generally, devices are set in various states using device-dependent commands
(device messages). Among these commands, the ∗RST command is used to re-
produce a known state of a device. Completion of device operation is invalidated
like level 2.
■ Specification of device number in WRITE @ statement
The device at the specified address is initialized at level 3.
■ Items subject to device initialization
(1) Device-dependent functions and states:
The specified device is set in a known state irrespective of its history.
(See the lists on the following pages.)
(2) ∗OPC command processing:
The specified device is set in the OCIS (Operation Complete Command Idle
State). The operation complete bit cannot be set in the standard event status
register. (
Section 7)
(3) ∗OPC? query processing:
The specified device is set in the OCIS (Operating Complete Command Idle
State). The operation complete bit cannot be set in the output queue. The
MAV bit is cleared. (
Section 7)
(4) Macro command:
Macro operation is disabled, setting the state in which macro commands
cannot be accepted. The designer can show macro definitions.
