This module expands two channels to 16 switch channels. All of the eight switches have a center position, a feature which provides true forward-stop-reverse steering. Three of the switches are self-neutralizing at both sides, two of them at one side only. Two of these modules can be installed
at the transmitter with a total of 32 switching functions at module stations A and B. At the receiver one 2-/16-channel NAUTIC-EXPERT switch
module (No. 4159) has to be provided.
