with lockout state is entered by executing the Fluke 1722A LOCKOUT statement when
using the 1722A as an IEEE-488 controller, or by sending the LOCKOUT command
described in Section 6 when you use the 1722A serial port to control the 5790A.
5-11. Remote State
When the Remote Enable (REN) line is asserted and the controller addresses the 5790A
as a listener, it enters the remote state. These conditions are met, for example, when a
1722A executes the BASIC statement (which sets the active input to INPUT 1):
10 REMOTE \ PRINT @6 'INPUT INPUT1'
In the remote state, the Measurement Display continues to display the results of
measurements as in local operation. The Control Display changes to:
add45f.eps
Front panel operation is restricted to use of the power switch and the "GO TO LOCAL
CONTROL" softkey. Pressing this softkey or sending the GTL (Go To Local) interface
message returns the 5790A to the local state. (One way to send the GTL interface
message is to execute the 1722A LOCAL statement.)
Note
The left most softkey does not toggle between AUTO and LOCKED in
remote state although AUTO/LOCKED is indicated. This key is available
only when the AUTO/LOCKED indication is in inverse video. (For
example: See Section 4-20.)
5-12. Remote with Lockout State
The remote with lockout state can be entered from remote or local with lockout, but not
directly from local. Remote with lockout is similar to the remote state, but restricted: the
"GO TO LOCAL CONTROL" softkey label does not appear on the Control Display as
shown below:
add46f.eps
To return the 5790A to the local with lockout state, the GPIB controller sends GTL.
(When you are using the 1722A as an IEEE-488 controller, you can do this manually by
executing a WBYTE statement.) To return the 5790A to the local state, the GPIB
controller unasserts the REN control line. (In the 1722A, the "LOCAL" BASIC statement
does this.)
Table 5-1 summarizes the possible Remote/Local state transitions.
