Module A-182 is a simple passive multi-connector similar to the multiples module A-180. In contrast to module A-180 each socket is equipped with a 3-position switch that allows to connect the corresponding socket to the internal bus #1 (left position), bus #2 (right position) or to turn the socket off (center position).
all switches in left position or all switches in right position: 8-fold multiple
four switches in left position and four switches in right position: two 4-fold multiple
X switches in left position, Y switches in right position and Z switches in center position: two separate multiples with some sockets turned off
Remark: The term "bus" in the module description has nothing to do with the A-100 bus.
