selected converter, including the frequency, attenuation, and slope.
LBC-4000-ST: CONV-A Submenu – Displays the current configuration of the selected
converter, including the frequency, attenuation, and slope.
•
REMOTE Submenu – The selections here allow you to select whether you control the
unit locally or remotely, set the unit address, the interface type, and the operating
parameters for that interface.
•
REDUND Submenu – The selections here allow you to identify the redundancy state and
