Cabling
The specific function of each 2000A89 BNC connector is determined by the
8900 module that is installed.
Loop-through Input
As in the 8900 frame, connectors J9 and J10 function as a loop-through
input connections (see
). Terminate the unused connector into 75
Ω
if the signal is not looped to other equipment.
