LC1
・
The LC1 command changes the remote mode of the PW-A unit into the local mode.

・
The LL1 command disables the LOCAL. As a result, the PW-A unit may not be brought
into the local mode even if the KEY LOCK / LOCAL KEY on the front panel is pressed.

Upon receiving the LL1 command, the PW-A unit automatically enters the remote mode,
where any panel operations are not accepted. To bring the PW-A unit into the local mode,
press the KEY LOCK/LOCAL key or issue the LC1 command. In the local mode, the PW-
A unit accepts panel operations. However, the KEY LOCK / LOCAL key is not functional if

the local mode.
The GP-IB messages REN, LL0 and GTL are invalid for the PW-A unit.
