HDMI TX Rear View

Multi-Format TX Rear View

Note: The HDMI TX and Multi-Format TX each have a DIP switch on the bottom (see page 21).

The following components are located on the rear of the HDMI TX and Multi-Format TX Modules

(from left to right):

Video In Connector (Multi-Format TX only)

The Video In connector on the Multi-Format TX is an HD-15 connector for analog video (composite,

Y/c, Y/Pb/Pr, RGB, RGBHV, or RGBS). Pinouts for analog video are on page 116.

Note: When an analog video source cable is plugged into the Multi-Format TX, the Video LEDs on

the front and on the Receiver turn green to show that video is present through the system. In

addition, one of the Analog Video LEDs on the front of the Multi-Format TX and the HDMI RX turns

green to show the type of video that is present through the system.

HDMI In Connector

The HDMI In connector is for digital video and embedded digital audio. When more than one audio

signal is present and the default “auto” mode is enabled, HDMI embedded audio takes precedence over

S/PDIF and analog audio.

When a NetLinx Central Controller is connected, an audio format SEND_COMMAND is available (the

Transmitter must be set for network connectivity via #3 Toggle) to select the desired audio source (see

page 80).

The HDMI connector has a center screw for locking capability. The HDMI connector also supports a

DVI-D signal with the use of a DVI-to-HDMI cable adapter.

Note: When a digital video source cable is plugged into the HDMI connector, the Video LEDs on the

front of the HDMI TX or Multi-Format TX and Receiver turn green to show that video is present

through the system.
