The NMX-ENC H.264 encoder is an audio/video encoder which supports
high-definition video and H.264 encoding. The encoder can stream either
unicast or multicast streams.
The NMX-ENC is available in two different versions: NMX-ENC-1100
(FG3201-01) and NMX-ENC-1105 (FG3201-02). The NMX-ENC-1105 has the
same features as the NMX-ENC-1100 and adds SDI input and pass-thru ports
on its rear panel.

Mounting the Encoder
You can mount the encoder in a rack by using an NMX-VRK V-Style Rack Shelf
(FG3201-60). The encoder also has rubber feet you can attach to the bottom of
the unit for table-top mounting. Consult the NMX-VRK V-Style Rack Shelf Quick
Start Guide for further information on mounting the encoder.

Step 1: Connecting the Encoder to a Video Output
There are several options for connecting audio and video sources to the
The multi-format video input source can accept DVI Video sources directly
with audio connected to corresponding audio input.
You can connect HDMI, component video, composite video, S-Video, and
RGB sources to DVI-I by using appropriate adapter cables. You can
connect the audio associated with these sources to the appropriate audio
jack on the rear panel of the encoder.
Digital audio embedded in HDMI through the DVI connector can be
multiplexed and used for encoding and pass through to monitor output.
On the NMX-ENC-1105, the SDI input can receive video with 2 channel
LPCM audio at 48kHz sampling frequency.
The following table lists the audio options for each video type:

Step 2: Connecting the Encoder to Your Network
Using Cat5 cable, connect LAN port 1 to your facility network.
Important: You must have access to a DHCP server to initially configure
WARNING: It is possible to disable LAN ports 2-4 and leave only port 1 enabled.
Since it is possible to turn off these ports, you should ALWAYS connect your
main network artery to port 1.
Note: The Ethernet switch in the encoder is intended to be used as a workgroup
extender switch for conveniently connecting devices such as PCs, touch panels,
and other network-connected A/V equipment. It is not a smart switch, and as
such other encoders or streaming devices should not be connected to the switch
ports on the encoder. If multiple encoders are to be used in a location they
should each have a dedicated facility network connection or a smart switch
should be added that can have multiple encoders connected to it.
Step 3: Applying Power to the Encoder
The encoder must be powered locally using the included power supply. Apply
power by connecting the power supply to the PWR port.
Retrieving the IP Address of the Encoder
You can retrieve the IP address and other configuration information for the
encoder by inserting a USB drive into the encoder and pressing the ID
pushbutton. The encoder creates and copies a text (.txt) file to the USB drive
with a list of configuration information including the IP address of the encoder.
Perform these steps to locate the IP address of the encoder:
Insert a USB drive into the USB port on the front panel of the encoder. The
USB LED beside the port appears green once the USB drive is mounted.
Press and hold the ID pushbutton for two seconds. When the LED appears
red, the encoder is copying a .txt file to the USB drive. The encoder is
finished transferring the file to the USB drive when the LED appears green
Remove the USB drive from the encoder and insert it into a PC or any
other device which can read the file.
On the PC, navigate to the USB drive. The filename contains the encoder's
serial number, IP address, and IP type (DHCP or Static). You can open the
file to view the MAC address, subnet mask, gateway, and DNS.
Note: If the encoder is unable to receive the IP address at the time of retrieval,
the filename will have "unavailable" listed in place of the IP address.
