3.5.3.5.2 STATUS REPORTING DIFFERENCES IN BIT 4886
The status register responses from the BOP 1KW and the BOP BIT/4886 are very different. If
these commands are used, then changes will be required in the user’s program. Commands
affected are: SYST:OPER, SYST:QUES, *ESR and *STB.
3.5.3.5.3 TRIGGER OPERATION DIFFERENCES IN BIT 4886
The BOP/BIT 4886 only supports *TRG while the BOP 1KW supports TRIGGER:SOURCE
EXTERNAL, BUS and IMMEDIATE. The command TRIG:SOUR BUS must be sent before using
trigger in the BOP 1KW.
3.5.4 IEEE 488 (GPIB) BUS PROTOCOL
Table 3-18 defines the interface capabilities of the BOP 1KW power supply (Talker/Listener) rel-
ative 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 3-19 and 3-20 define the messages sent by the BOP, or received by the
BOP, 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 BOP power supply operat-
ing as either a Talker or a Listener. (See PAR. 3.5.3.1 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 SR1
Complete Capability. The interface sets the SRQ line true if there is an enabled ser-
vice request condition.
Remote/Local RL1
Complete capability. Interface selects either local or remote information. In local
mode the BOP 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. LOCAL function key can be disabled using keypad lockout
command (see Appendix B, PAR. B.135) so that only the controller or a power on
condition can restore Local mode.
Parallel Poll PP0 No Capability
Device Clear DC1
Complete Capability. BOP accepts DCL (Device Clear) and SDC (Selected Device
Clear).
Device Trigger DT1 Respond to *TRG and trigger functions.
Controller C0 No Capability
