AT-OMNI-111 / AT-OMNI-112
11
Installation
Both the AT-OMNI-111 and AT-OMNI-112 provide RS-232 over IP, allowing communication between an automation
system and an RS-232 device. This step is optional.
1.
Use wire strippers to remove a portion of the cable jacket.
2.
Remove at least 3/16” (5 mm) from the insulation of the RX, TX, and GND wires.
3.
Insert the TX, RX, and GND wires into correct terminal on the included Phoenix block. If using non-tinned
stranded wire, presss the orange tab, above the terminal, while inserting the exposed wire. Repeat this step for
the TX, RX, and GND connections.

Connection Instructions
1.
Connect an Ethernet cable from the
Eth
port on the encoder to a PoE-capable switch on the Local Area Network
(LAN). If using the dual-channel encoder, connect a separate Ethernet cables to
Eth 1
and
Eth 2
ports.
2. Connect an
HDMI cable from each source to the
HDMI
ports on the encoder.
3.
RS-232 (optional)
• Connect the the RS-232 controller/automation system to the
RS-232
port on the encoder.
• Connect the RS-232 device to the
RS-232
port on the decoder.
4. Once power is applied, the
PWR
indicator, on the front panel, will turn red, then amber.
IMPORTANT:
If a PoE-capable switch is not available, then the 48V DC power supply (sold
separately) must be connected to the encoder.
NOTE:
Typical DB9 connectors use pin 2 for TX, pin 3 for RX, and pin 5 for ground. On some
devices, pins 2 and 3 are reversed.
