2.4.3 Device Clear (DCL and SDC)

In response to a DCL or SDC from the IEEE488 bus, the Digital488HS/32 pulses the

oClear control line for 1µsec. In addition, the input port is forced Empty and the

output port is forced to its power-on default value. For more information, see PTO

default switches,S4 and S5.

2.4.4 Group Execute Trigger (GET)

When the Digital488HS/32 recognizes a GET, the Digital488HS/32 pulses the

oTrigger control line for 1µsec.

2.4.5 Interface Clear (IFC)

IFC places the Digital488HS/32 in the Talker/Listener Idle State.

2.4.6 Serial Poll Enable (SPE)

When Serial Poll Enabled (SPE), the Digital488HS/32 sets itself to respond to a serial

poll with its serial poll status byte if addressed to talk. When the serial poll byte is

accepted by the controller, any pending SRQs are cleared. The Digital488HS/32

continues to try to output its serial poll response until it is Serial Poll Disabled (SPD)

by the controller.

2.4.7 Serial Poll Disable (SPD)

Disables the Digital488HS/32 from responding to serial polls by the controller.

2.4.8 Unlisten (UNL)

Unlisten (UNL) places the Digital488HS/32 in the Listener Idle State.

2.4.9 Untalk (UNT)
