Multiline
The GPIB interface and the computer controller implement the Acceptor Handshake,
Control Source Handshake, Listener, and Talker functions. No user action is required. The
unit's ADR (Addressed) LED turns on when the power supply is addressed to listen

or talk.
Device Clear The power supply will implement Device Clear regardless of whether it is in local or
remote control. Device Clear is typically used to send all or selected devices to a
known state with a single command. The power supply will be set to Initial (Power
On) Conditions after Device Clear.

ibfind "devname"

Description
Device must properly transfer a multiline message.
Device must properly receive remote multiline
messages.
Device must be able to transmit.
Device must receive commands and data.
Device can be initialized to a previously determined
state.
A device function can be initiated by a talker on the
bus.
Upon controller request, device must uniquely
identify itself if it requires service.
Device must be able to operate from front panel and
via remote information from bus.
Device can asynchronously request service from
controller.
All talkers on the bus assume a serial poll mode.
Each device when addressed will provide an 8-bit
word of status information.
Address the unit (devname or device name as
configured originally with ibconf)
Low level command directed to entire bus, or
Device-dependent command directed to a
specific device.
