Annunciators
The five annunciators along the top of the display indicate the following conditions:
SRQ — Turns on when the unit requests service over the IEEE-488 bus. Program-
ming the Service Request Enable Register allows you to control which conditions
will generate an SRQ (see Section 5 of the Model 7002-HD Reference Manual).
REM — Turns on to indicate that the Model 7002-HD is in remote when used over
the IEEE-488 bus. The Model 7002-HD can be placed in remote by addressing it
to listen with the bus REN line true.
TALK — Turns on to indicate that the Model 7002-HD is the active talker on the
IEEE-488 bus. The unit can be placed in the talker active state by sending it the
correct bus talk command, which is derived from the primary address.
LSTN — Turns on when the unit is an active IEEE-488 bus listener. The Model
7002-HD can be placed in the active listener state by addressing it to listen.
ARM — Turns on when the Model 7002-HD is taken out of the idle state. A scan
can only be performed with the Model 7002-HD out of the idle state.
