If you connect the product to a cable system that does not
support redundant media, connect the tap dropline to the BNC
connector labeled channel A. Channel B is left open.
If the cable system is redundant, connect the product so that
all devices on the network use the same cable for the same
channel. That is, all channel A connectors connect to one
cable; all channel B connectors connect to the other.
