a Power connector — Connect the standard IEC power cord from a 100 to 240 VAC,
50-60 Hz power source into this connector. The front panel control and input selection
buttons light in sequence during power-up.
b Analog video connectors — Connect video sources to the 15-pin HD connectors.
Each accepts RGB, YUV, RGBcvS, S-video, and composite video (see Analog Video
Wiring on page 12).
c HDMI input connectors — Connect video sources to the HDMI connectors.
TIP: Use Extron HDMI LockIt Lacing Brackets to secure HDMI cables to the device
(see HDMI Connections on page 12).
d DTP input connectors (IN1608 models only) — Connect a DTP 230 transmitter to
either DTP In RJ-45 connector to send all signals over a single twisted pair cable (see
Twisted Pair Recommendations for DTP Communication on page 13 for wiring
and cable recommendations). This connection supports the following:
• HDCP-compliant digital video
• Embedded digital audio de-embedding from the TMDS source or analog audio
• DTP standard RS-232 and IR pass-through signals on associated 5-pole captive
screw connectors.
• Remote power to DTP 230 transmitters
ATTENTION:
• Do not connect this connector to a computer or telecommunications network.
• DTP remote power is intended for indoor use only. No part of the network that
uses DTP remote power should be routed outdoors.
Signal LED — Lights when the scaler is receiving an active video signal from a DTP
transmitter.
Link LED — Lights when a valid link is established to a DTP transmitter.
RS-232 Over DTP port — To pass bidirectional serial control between
DTP-compatible devices, connect a control device to the 5-pole captive
screw connector. This port includes only the 3 poles labeled “RS-232.”
IR Over DTP port — To transmit and receive IR signals, connect a control
device to the 5-pole captive screw connector. This port includes only the
2 poles labeled “IR” and shares the ground pole with the RS-232 port.
NOTE: RS-232 and IR data can be transmitted simultaneously.
