3.6.1 RS-485 OPERATION
See PAR. 2.7.2 for RS-485 connections.
See PAR. 3.3.18 to change the RS-485 Address.
See PAR. 3.3.16 to change the RS-485 Baud Rate.
3.6.2 GPIB OPERATION (IF OPTION INSTALLED)
See PAR. 2.7.3 for GPIB connections.
See PAR. 3.3.17 to change the GPIB Address.
3.6.2.1 IEEE 488 (GPIB) BUS PROTOCOL
Table 3-4 defines the interface capabilities of the KLN 750W power supply (Talker/Listener) rela-
tive 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/Listener). Tables 3-5 and 3-6 define the messages sent by the KLN 750W, or received
by the KLN 750W, via the IEEE 488 bus in IEEE 488 command mode and IEEE 488 data mode,
respectively. These messages are enabled during the “handshake” cycle, with the KLN 750W
power supply operating as either a Talker or a Listener. (See PAR. 3.6.3.1 to change the GPIB
address.

FUNCTION
SUBSET
SYMBOL
COMMENTS
Source Handshake SH1 Complete Capability (Interface can receive multiline messages)
Acceptor Handshake AH1 Complete Capability (Interface can receive multiline messages)
Talker T6 Basic talker, serial poll, unaddress if MLA (My Listen 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 750W executes 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 750W accepts DCL (Device Clear) and SDC (Selected
Device Clear).
Device Trigger DT0 No Capability
Controller C0 No Capability
