  It's a 'terminator'.  A 10Base-2 network needs to have a terminator at
each end to work properly.  That means TWO terminators.  The smallest,
properly terminated 10Base-2 network would be a 'T' connector with two
terminators on it.  In fact, terminators always go on 'T's

Example 10Base-2 network:

Terminator T ------ T ------ T Terminator
       Computer  Computer   Hub

  With just one terminator, your hub thinks it is detecting a valid
network attached to the bnc connector.  But since you don't have a valid
network, you get transmission problems.

  You should be fine without a terminator on the BNC connector.
