10.4.4Establishing Remote Control

Upon starting execution, the LBA-PC initializes itself in Local Mode.

The LBA-PC enters Remote Mode when it receives a :REM command or is addressed to listen when the REN line is true. The LBA-PC responds with REM when it receives the :REM command. There is no response when the REN line is used to enter Remote Mode.

The LBA-PC enters Local Mode when it receives the :LOC command or the REN line is false. The LBA- PC responds with LOC when it receives the :LOC command. There is no response when the REN line is used to enter Local Mode. In Local Mode the LBA-PC receives and responds to remote commands.

The LBA-PC automatically enters what is called the lockout state when going from Local to Remote Mode. This is equivalent to entering the operator password in the Options Password menu item. While in the lockout state, access is denied to many of the LBA-PC menu items. The LBA-PC automatically exits the lockout state when returning to Local Mode. You can override the lockout state by sending the PSW command or by selecting Options Password and entering the operator password.
