Connections
Channel 0 is connected to the dedicated DigiNet port (AUX B) of a given
6800 series frame. To allow several DNHs to be contained within a single
frame without excessive loading of the transceivers, it is not terminated.
Auxiliary B (Channel 0) can be disabled to allow several DNH modules
in a single frame to be isolated from each other. An external terminator
should always be installed on the frame’s dedicated DigiNet connector.
The other eight channels are connected to the eight output BNCs located
on the backplane (the backplane’s input BNC is unused).
