6 Using Your VP-12NHD 1:12 + 3 UXGA / CAT5 Distributor
This section describes how to connect the
VP-12NHD 1:12 + 3 UXGA / CAT5
Distributor. The example in Figure 3 illustrates how to output a computer
graphics signal from a computer to up to 12 local monitors, as well as how to
transmit it over UTP cabling to 3
TP-120 XGA Line Receiver units.
To connect the
VP-12NHD and up to 3 TP-120 XGA Line Receiver units, do
the following:
1. Connect a computer graphics source (for example, a computer) to the
INPUT HD15F connector.
2. Connect the OUTPUT HD15F connectors to up to 12 acceptors (for
example, Local Display 1 to Local Display 12).
3. Ensure that the ID BIT switch on the underside of the
VP-12NHD is set to
ON (by sliding it to the left). This would enable a notebook or laptop (if
connected instead of a computer) to output a VGA signal to an external
VGA monitor.
4. On the
VP-12NHD, connect
1
the CAT5 RJ-45
2
:
OUT 1 connector to the LINE IN RJ-45 connector on a
TP-120 unit, and
connect the XGA OUT connector on that
TP-120 unit to Display 1
OUT 2 connector to the LINE IN RJ-45 connector on a second
TP-120 unit,
and connect the XGA OUT connector on that second
TP-120 unit to Display 2
OUT 3 connector to the LINE IN RJ-45 connector on a third
TP-120 unit,
and connect the XGA OUT connector on that third
TP-120 unit to Display 3
5. Connect the power cord
3
(not illustrated in Figure 3).
6. On the
TP-120 units, if necessary:
Set the H SYNC and V SYNC switches
4
on the underside
Adjust
5
the video output signal level and/or cable compensation
equalization level
7. On the
VP-12NHD, if required:
Adjust
5
the blue, green and red signal levels
Set the VS and HS switches
6
1 Via UTP cabling, with a range of more than 300ft (>100m): see section 6.1
2 The TP-120 units may be powered via this connector (instead of via the 12VDC external supply)
3 We recommend that you use only the power cord that is supplied with this machine
4 By default, both switches are set down (for negative V SYNC and H SYNC polarity)
5 Use a screwdriver to carefully rotate the trimmer, adjusting the appropriate level
6 By default, both switches are set to the right (to NORMAL) to retain the VS and HS polarity
