HELP
An object that uses transactions to send
low-level interface commands and data by way
of HP-IB and VXI.  This feature is available
in HP VEE-Test only.

Interface Operations should be used for
interface-specific tasks, or for special
cases where communication with devices via
Direct I/O or an Instrument Driver does not
afford the necessary level of control.

USE
Use Interface Operations for low-level
operations such as:
* Sending non-standard HP-IB addressing
sequences.
* Sending an HP-IB group trigger message, or
pulling on VXI trigger lines.
* Sending arbitrary bytes via HP-IB, with or
without ATN true.
* Sending clear and reset commands to either
the VXI or HP-IB interfaces.
* Sending IEEE 488.1 defined multi-line
messages.

To use Interface Operations you must add
one or more transactions.  To do this, click
on Add Trans in the object menu.
Transactions are listed as lines of text in
the open view of the object.  To edit a
transaction, double click on the transaction
and complete the resulting dialog box.

LOCATION
I/O ==> Advanced I/O ==> Interface Operations

OBJECT MENU

* Config - Displays the bus configuration and
allows you to change to another interface or
to specify a timeout.  Multiple interfaces of
the same type are distinguished by their
select codes (e.g., "hpib7" and "hpib8").

* Add Trans - Adds a transaction to the end
(bottom) of the list.

* Insert Trans - Inserts a transaction before
(above) the currently highlighted
transaction.

* Cut Trans - Cuts (deletes) the currently
highlighted transaction, but saves it in the
transaction "cut-and-paste" buffer.

* Copy Trans - Copies the currently
highlighted transaction to the transaction
"cut-and-paste" buffer.

* Paste Trans - Pastes a transaction,
previously "cut" or "copied" to the buffer,
in the position before the currently
highlighted transaction.

SHORT CUTS
To quickly insert a transaction, place the
cursor on a transaction.  Press [CTRL-O] to
insert a transaction over the transaction
where you placed the cursor.

To quickly delete ("kill") a transaction,
place the cursor on that transaction and
press [CTRL-K].

To paste a transaction from the "kill"
buffer press [CTRL-Y].

To quickly move to the next or previous
transaction, press [CTRL-N] or [CTRL-P]
respectively.
