10.4 Command Formats and Responses

Commands to the LBA-PC will not normally generate a response back to the host controller, unless the command:

•Changes remote/local mode

•Is a query

•Initiates an operation that produces results

•Generates an error

10.4.1IEEE 488.1 Command Support

The LBA-PC in combination with an appropriate National Instruments GPIB board conforms to the IEEE 488.1 standard according to the following Subset Codes:

SH1, AH1, T6, L4, SR1, RL2, PP0, DC1, DT0, E2, C0

These Subset Codes are defined in the IEEE 488.1 standard and describe interface capabilities of the LBA-PC.

The following multiple line interface message commands are supported by the LBA-PC:

GTL	-	Go To Local (0x01). When the LBA-PC detects the GTL message it returns
		to local command mode.
LLO	-	Local Lockout (0x11). When the LBA-PC detects the LLO message it enters
		what is called the lockout state. This is equivalent to entering the operator
		password in the Options Password menu item. While in the lockout state
		access is denied to many of the LBA-PC menu items. When the LBA-PC
		exits the lockout state access to all menu items is restored.
MLA	-	My Listen Address (0x20 to 0x3e).
MSA	-	My Secondary Address (0x60 to 0x7e).
MTA	-	My Talk Address (0x40 to 0x5e).
PPC	-	Parallel Poll Configure (0x05). Handled by GPIB board and NI-488.2M.
PPD	-	Parallel Poll Disable (0x70 to 0x7e). Handled by GPIB board and NI-
		488.2M.
PPE	-	Parallel Poll Disable (0x60 to 0x6e). Handled by GPIB board and NI-
		488.2M.
PPU	-	Parallel Poll Unconfigure (0x15). Handled by GPIB board and NI-488.2M.
SPD	-	Serial Poll Disable (0x19).
SPE	-	Serial Poll Enable (0x18).
