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 (LOCAL] 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 synthesizer 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 that 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:
