IEEE-488 PROGRAMMING
To send GTL, the controller
must perform the following
panel RESET key, in that the instrument
will return to the
sequence:
SETUP 1 configuration.
Table 4-7 lists factory default con-
ditions for the instrument
after it receives a DCI..
1. Set ATN true.
2. Address the Model 194 to listen.
3. Place the GTL command byte on the data lines.
HP-85 Programming Example-Place
the instrument in the
remote and LOCAL
lockout modes with the following
statements:
REIIOTE 7w3
L. 11, c: H I. L 0 iL ,::: 0 Ii T 7
Verify that the instrument
is in remote and that LOCAL
is locked out.
Send GTL as follows:
Note that the instrument
goes into the local mode, and
that operation
of the front panel keys has now been
restored.
Model 8573 Programming
Example-Place
the instrument
in the remote and LOCAL lockout modes with the follow-
ing statements:
Verify that the instrument
is now in remote, and that the
LOCAL key is locked out.
Now send GTL with the following
statement:
After the above statement is executed, the instrument
will
revert to the local mode, and operation of the front panel
keys will be restored.
4.8.5 DCL (Device
Clear)
The DCL command may be used to clear the Model 194
and return the unit to default conditions.
Essentially, this
command will perform
the same function
