KLN Series 051614
3.6.2.1 IEEE 488 (GPIB) BUS PROTOCOL
Table 3-4 defines the interface capabilities of the KLN power supply (Talker/Listener) relative to
the IEEE 488 (GPIB) bus (reference document ANSI/IEEE Std 488: IEEE Standard Digital Interface
for Programmable Instrumentation) communicating with a Host Computer—Controller (Talker/Lis-
tener). Tables 3-5 and 3-6 define the messages sent by the KLN, or received by the KLN, via the
IEEE 488 bus in IEEE 488 command mode and IEEE 488 data mode, respectively. These mes-
sages are enabled during the “handshake” cycle, with the KLN power supply operating as either
a Talker or a Listener.

SYMBOL
COMMENTS
Source Handshake SH1 Complete Capability (Interface can receive multi-
line messages)
Acceptor Handshake AH1 Complete Capability (Interface can receive multi-
line messages)
Talker T6 Basic talker, serial poll, unaddress if MLA (My Lis-
ten Address) (one-byte address)
Listener L4 Basic listener, unaddress if MTA (My Talk Address)
(one-byte address).
Service Request SR0 No Capability.
Remote/Local RL1 Complete capability. Interface selects either local
or remote information. In local mode the KLN exe-
cutes front panel commands, but can be set to
remote mode via IEEE 488 bus. When in Remote
mode all front panel keys are disabled except
LOCAL function key.
Parallel Poll PP0 No Capability
Device Clear DC1 Complete Capability. KLN accepts DCL (Device
Clear) and SDC (Selected Device Clear).
Device Trigger DT0 No Capability
