Connection Instructions
1. Connect an Ethernet cable from the ETHERNET port on the decoder to a PoE-capable switch on the Local Area
Network (LAN). If using the dual-channel decoder, connect a separate Ethernet cables to ETHERNET 1 and
ETHERNET 2 ports.
2. Connect an HDMI cable from the HDMI OUT port on the decoder to a display. If using the dual-channel
decoder, connect an HDMI cable from each HDMI OUT port to a display.
3. RS-232 (optional)
• Connect the RS-232 controller/automation system to the RS-232 port on the decoder.
• Connect the RS-232 device to the RS-232 port on the decoder.
4. External Audio (optional)
• Connect the audio inputs to the decoder, as required.
• Connect the audio outputs to the decoder, as required.
5. IR (optional)
• IR emitter
Connect the IR emitter to the TX and GND pins of the RS-232 2 port. The IR emitter must be placed no
more than 1” from the IR sensor on the device, in order to function properly.
• IR extender
Connect the IR extender from the RX and GND pins of the RS-232 2 port to the associated pins on the
control system.
6. Once power is applied, the PWR indicator, on the front panel, will turn red, then amber, then green.
IMPORTANT: If a PoE-capable switch is not available, then the 48V DC power supply (sold
separately) must be connected to the decoder.
Installation
IMPORTANT: When using analog audio inputs on the OmniStream decoder, the decoder must be
powered using the 48V power supply (AT-PS-48083-C). This power supply is sold separately and
can be purchased from Atlona.
NOTE: For dual-channel decoders, only the RS-232 2 port supports both serial and IR. Single-
channel decoders only support IR on the RS-232 2 port. The IR emitter or IR receiver must always
be connected to this port. Refer to IR Control (page 36) for more information.
