10.4.2 IEEE 488.2 Common Commands
The following IEEE 488.2 common commands are supported by the LBA-PC.
*IDN? - Identification Query
*RST - Reset
*CLS - Clear Status Registers
*ESE - Event Status Enable Write
*ESE? - Event Status Enable Query
*ESR? - Event Status Register Query
*SRE - Service Request Enable Write
*SRE? - Service Request Enable Query
*STB? - Status Byte Register Query
All other IEEE 488.2 common commands are not recognized by the LBA-PC and will return a
Command Error.
10.4.3 LBA-PC Command and Data Formats
The LBA-PC does not support the IEEE 488.2 specification of sending multiple commands separated
by semicolons. Each command must be sent separately and terminated by asserting the EOI line with
the last byte sent.
The following are some typical formats for command and response transmissions:
cmd: *CCC(^END)
cmd: *CCC?(^END)
cmd: *CCC _ key=value(^END)
cmd: *CCC _ key=value;key=value;…;key=value(^END)
rsp: CCC _ key=value;key=value;…;key=value;;(^END)
rsp: CCC _ FrameNumber=f;#dn..n (DAB)…(DAB)(^END)
Where:
* = Precedes a 488.2 common command
: = Precedes a LBA-PC command
CCC = Three character command code, case is ignored
? = Query character to illicit a response
