Direct (1:1) Connections
This section describes direct (1:1) connections (definition below) and shows you
connection examples. Definition of a Direct (1:1) connection:
a single length of cable joins the Black Box device and your equipment;
there is no structured cabling system or any other connection in-between.
Notes:
1. Some user equipment need additional signals on the connector. These may not be
supported by the Black Box device or your cable. The normal way to overcome
this is to loopback - on your equipment - one of the output lines to the required
input. Refer to the documentation supplied with your equipment, or the supplier of
the equipment, for information on which loop-backs, if any, are required.
2. Other than a specific requirement at your equipment (as in note 1), do not connect
unused pins on either connector.
3. Protective Ground (P/GND) terminates on the connector and so does not have a
pin number.
