SME 211 • Setup Guide
The Extron SME 211 is a high performance H.264 streaming media encoder for streaming audio and video signals over IP
networks. It accepts an HDMI signal with embedded audio and an analog audio signal. The SME 211 supports unicast and
multicast streaming protocols, including RTMP. The SME 211 can stream at two different resolutions and bit rates concurrently,
supporting up to six simultaneous streams with push and pull streaming. Built-in audio mixing and DSP features enable enhanced
audio processing without requiring external mixing and DSP equipment.
Mounting the SME 211
The SME 211 is housed in a 1U high, half rack width metal enclosure that can sit on a table with the provided rubber feet or
can be mounted in a rack or under table. Select a suitable mounting location, then choose an appropriate mounting option.
Before connecting the SME 211, turn off all devices that will be connected and then make all external device connections to the
SME 211 before applying power to the devices.

Power Connection
A
100-240 VAC power input
– Connect the provided IEC cord. Verify the front panel buttons and LCD illuminate (see
Front
Panel Features
on page 2).
Control System and External Device Connections
The SME 211 can be configured and controlled from the front panel USB Mini-B Config port (see
figure 4
,
D
on page 2) using
SIS commands and DataViewer via telnet port 23, or from the LAN port using a standard web browser. Because the LAN port
must be connected for streaming output, Extron recommends using it for configuration, remote control, and firmware upgrades.

USB receptacle
– Attach an external USB storage device to load mask images or other files to the user file system.
A mouse and keyboard can also be attached to this receptacle for network setup.

Remote
— To control the SME 211 using SIS commands over RS-232, connect the host RS-232 cable to the rear panel
(see the illustration at right) with a 3-pole captive screw connector for bidirectional (±5 V) serial host control. The default
protocol for this port is
9600 baud
,
no parity
,
8 data bits
,
1 stop bit
, and
no flow control (handshaking)
.
G
Reset button and LED
— The SME 211 has several reset modes to return user-defined configuration settings or all
settings back to factory defaults. The LED blinks to indicate the desired reset mode, and provides the reset status during
the reset operation. For information on selecting the reset mode, see the
SME 211 User Guide
.
H
RJ-45 Ethernet connector (LAN)
— Use a standard Ethernet cable to connect to a network. The table at right has the
default network settings.
NOTE:
To connect the SME 211 directly to a computer Ethernet port, use a
crossover Ethernet cable.
