DECServer 90L+ startup help

The termination is 50 ohms.

BTW: When dealing with RF (radio frequencies) and coax - an "open" to DC is a
"short" to RF. In other words, the entire signal is refelected back off of
the end of an unterminated RF line (in this case Ethernet) - which
essentially cancels ALL of the signal.

BTW2: One must also match the required 50 ohm impedence with the proper
transmission line - which in the case of thin Ethernet would typically be
RG-58/U.
