1
DTP output connectors — Connect STP cables between these connectors
(labeled OUT) and up to four compatible Extron DTP receivers, XTP matrix
switcher inputs, or third-party HDBaseT-enabled sink devices.
2
TP mode switch — This three-position switch enables you to select between
the following twisted pair output modes:
• DTP mode — Passes video signals, and allows bidirectional RS-232 and IR
control between the DTP output card and DTP receivers via the OVER TP
control connectors (see
figure 23 ,
3
on the previous page).
Remote power over DTP is available via the 2-pole DTP POWER connector
(
4
).
• XTP mode — Passes video signals, and allows bidirectional RS-232 and IR
control between the DTP output card and XTP matrix switcher inputs via the
OVER TP control connectors (
3
). Remote power is not supported.
• HDBT mode — Passes video signals, and allows bidirectional RS-232 and
IR control between the DTP output card and HDBT sink devices via the
OVER TP control connectors (
3
). Remote power is not supported.

OVER TP control connectors — Each DTP output connector has an RS-232
and IR control connector associated with it. Connect serial RS-232 signals,
modulated IR signals, or both, to these 3.5 mm, 5-pole captive screw connectors
(the ground pin is shared) to insert bidirectional RS-232 and IR communications
(including SIS commands) into the signal passing through the associated DTP
outputs.
Wiring the serial and IR ports:
Figure 24 shows how to wire the OVER TP RS-232 and IR connectors. For these
connectors, the Ground (G) pin is shared by both signal types and both signal
types can be active at the same time.

NOTE: The length of the exposed wires is important. The ideal length is
3/16 inch (5 mm).

DTP POWER connector — Connect a 12 V, 4 A power supply (such as the
Extron PS 124) to this 2-pole captive screw connector to provide power to
receivers connected to any or all of the DTP output connectors on the card. The
connected receivers must be classified as Powerable Endpoints (PEP).
