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.

Wiring the RS-232 and IR Connectors
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).
Output resolutions
•
Outputs 1 and 3
— These two outputs generate resolutions with pixel clocks up to
165 MHz, which supports resolutions of 2048x1200 and 1920x1200 at 60 Hz.
•
Outputs 2 and 4
— These two outputs generate resolutions with pixel clocks up to
300 MHz, which provides support for 4K at 30 Hz and 2560x1600 at 60 Hz.
A possible configuration might consist of a single channel greater than 165 MHz plus two
channels that are less than 165 MHz, as shown in figure 25. In this example, output 2 is
configured to support up to 4K at 30 Hz, and outputs 3 and 4 are configured to support
up to 1920x1200 at 60 Hz.
