the rear panel of the instrument. This interface can be used to connect a controller for
remote control purposes. The connection must be made using a shielded cable.

On power on, the amplifier is always in the local state (manual operation). At the front
panel display LOCAL will be indicated.
If a controller addresses the amplifier as a listener by sending the REMOTE
command, the amplifier changes to the remote state and remains in this state even
after termination of data transmission. This is indicated by the message LAN at the
front panel display.
A change of the control mode is only possible when the amplifier is in STANDBY
mode.
There are two methods to return to the local state:

By the command LOCAL.

By pressing the Control key on the front panel of the amplifier.
