The 3468A
may be connected
anywhere in the interface loop. The loop consists
of up to 30 devices. When installing or removing the 3468A (or any other device)
ALWAYS
turn off the calculator first. Then simply disconnect the loop in one place
and connect the 3468A at that point. Remember,
the interface cables must form
a continuous loop. All HP-IL connectors are designed to ensure proper orientation
and indicate the direction of information transfer.
When
the calculator
is turned
on it will automatically
assign
addresses
to each
device depending on its position in the loop. The first device in the loop after the
calculator (in the direction of information flow) will have an address of "1". The
second
device
will have an address
of "2",
and so on around
the loop. The
calculator has an address of "0". The device must be "SELECTED"
by its address
before any command
or information can be sent to it.
