Remote
Remote causes an instrument to change from local control to
remote control. In remote control, the front panel keys are disabled
(except for the
key and the POWER switch), and the amber
REMOTE annunciator is lighted. The syntax is:
where the device selector is the address of the instrument appended
to the HP-IB port number. Typically, the HP-IB port number is 7,
and the default address for the swept CW generator is 19, so the
device selector is 719. Some BASIC examples:
10
REMOTE 7
which prepares all HP-IB instruments for remote operation (although
nothing appears to happen to the instruments until they are
addressed to talk), or
10
REMOTE 719
which affects the HP-IB instrument located at address 19, or
10
REMOTE719, 721, 726, 715
which effects four instruments t h a t have addresses 19, 21, 26, and 15.

Local Lockout
Local Lockout can be used in conjunction with REMOTE to disable
the front panel (LOCAL) key. With the (LOCAL) key disabled, only the
controller (or a hard reset by the POWER switch) can restore local
control. The syntax is:
