Appendix A Remote Command/Error Message Operation

The LBA-PC can be controlled as a remote device via GPIB. For the most part, communications between the LBA-PC and the host controller will follow the data format and coding protocols outlined in the IEEE 488.1 and 488.2 standards.

A.1 IEEE 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).
UNL	Unlisten (0x3f).
UNT	Untalk (0x5f).

The following IEEE 488.1 commands are not supported:

DCL, GET, SDC, TCT
