A.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)…(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

_	=	an ASCII SPACE character (0x20)
key	=	command dependent parameter
value	=	value assigned to key
(DAB)	=	8 bit data byte in binary format
(^END)=		indicates that EOI is asserted with the last byte sent.

A.4 Configuration Command Parameters

Type Description

LSelection. ASCII numeric value corresponding to the desired selection. All selections start with a base value of zero.

I Integer. ASCII numeric value in integer format.

BBoolean. ASCII numeric integer value. 0 = false. 1 = true.
