Local, Remote, and Local Lockout

The local, remote, and remote with local lockout modes may be used for various degrees of front-panel control while a program is running. The logic analysis system will accept and execute bus commands while in local mode, and the front panel will also be entirely active. If the HP 16500C is in remote mode, the system will go from remote to local with any touchscreen, mouse, or keyboard activity. In remote with local lockout mode, all controls (except the power switch) are entirely locked out. Local control can only be restored by the controller.

Cycling the power will also restore local control, but this will also reset certain HP-IB states. It also resets the system to the power-on defaults and purges any acquired data in the acquisition memory of all the installed modules.

The instrument is placed in remote mode by setting the REN (Remote Enable) bus control line true, and then addressing the instrument to listen. The instrument can be placed in local lockout mode by sending the local lockout (LLO) command. The instrument can be returned to local mode by either setting the REN line false, or sending the instrument the go to local (GTL) command.
