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 SME211
The SME211 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 SME211, turn off all devices that will be connected and then make all external device connections to the
SME211 before applying power to the devices.

Panel Features on page2).
Control System and External Device Connections
The SME211 can be congured and controlled from the front panel USB Mini-B Cong 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 conguration, remote control, and rmware upgrades.
USB receptacle – Attach an external USB storage device to load mask images or other les to the user le system.

A mouse and keyboard can also be attached to this receptacle for network setup.
Remote — To control the SME211 using SIS commands over RS-232, connect the host RS-232 cable to the rear panel
F
(see the illustration at right) with a 3-pole captive screw connector for bidirectional (±5V) 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).
Reset button and LED — The SME211 has several reset modes to return user-dened conguration settings or all
G
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 SME211 User Guide.
RJ-45 Ethernet connector (LAN) — Use a standard Ethernet cable to connect to a network. The table at right has the
H
default network settings.
NOTE: To connect the SME211 directly to a computer Ethernet port, use a
crossover Ethernet cable.

Figure 2. Audio Input Captive Screw Connector Wiring
ATTENTION:
• The length of the exposed wires in the stripping process is critical. The ideal length is 3/16 inch (5 mm). If longer,
the exposed wires may touch, causing a short circuit between them. If shorter, the wires can be easily pulled out
even if tightly fastened by the captive screws.
• La longueur des câbles exposés est primordiale lorsque l’on entreprend de les dénuder. La longueur idéale est de
5mm (3/16inches). S’ils sont un peu plus longs, les câbles exposés pourraient se toucher et provoquer un court
circuit. S’ils sont un peu plus courts, ils pourraient sortir, même s’ils sont attachés par les vis captives.
• Do not tin the wire leads before installing into the connector. Tinned wires are not as secure in the connector and
could be pulled out.
• Ne pas étamer les conducteurs avant de les insérer dans le connecteur. Les câbles étamés ne sont pas aussi bien
xés dans le connecteur et pourraient être tirés.
