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

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 congured and controlled from the front panel USB Mini-B Cong port (see ﬁgure 4,

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 conguration, 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 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).

Reset button and LED — The SME211 has several reset modes to return user-dened conguration 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.

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.

Input Connections

HDMI input – Connect an HDMI (or DVI with a suitable adapter) source device to input.

Analog audio input – Connect a balanced or unbalanced stereo line level audio device to this 5-pole 3.5 mm captive screw

connector. Wire the connector as shown in gure 2.

Do not tin

the wires!

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

5mm (3/16inches). 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.

Output Connections

HDMI preview output – Connect an HDMI (or DVI with a suitable adapter) display device to this HDMI output connector for

easy size and position setup and to access the internal web browser.

Power LED —

• Green — The power is on and the unit is operational.

• Blinking Green — The power is on but the unit is still booting (not operational).

Alarm LED — Lights red steadily when one or more alarms are triggered.

Config port — Connect a control device to this port with a USB Mini-B cable (not supplied). Use this port to send SIS

commands to the SME211 for device conguration and control.

NOTE: For information on using this port for device configuration and control and for a list of available SIS commands,

see the SME211 User Guide.

USB storage port – Connect a USB compatible media device to this port. The device can be any standard external hard

drive or USB ash drive formatted with a compatible le system, or a mouse or keyboard for network setup. Compatible

formats include FAT32, VFAT, and NTFS.

HDCP LED – LED Lights red steadily if If HDCP content is detected.

NOTE: Streaming of HDCP content is not currently supported. When HDCP content is detected, a green screen is

displayed on the video output.

HDMI LED – LED lights green steadily when HDMI video input sync is detected.

Audio Signal and Clip LEDs

• Audio Output Indicators – Stacked red (signal clipping) and green (signal present) LEDs for HDMI and line input

channels.

• Audio Output Indicators – Stacked red (signal clipping) and green (signal present) LEDs for the output channel.

For both the Audio Input and Audio Output indicators, the green signal LED varies in brightness corresponding to the input

signal level. It begins to light at -60 dBFS, increasing to full intensity corresponding to signal level increases. When the

signal level reaches -3 dBFS or above, the red clipping LED lights and remains lit as long as the signal remains about -3

dBFS. When it falls below that level, the red LED remains lit for 200 milliseconds, after which the display resumes real-time

monitoring of the signal level.

Streaming controls with LED indicators – The front panel buttons control all enabled streams concurrently:

• Stream – Press to start live streaming or resume live streaming after pausing. When the unit is streaming, the LED

lights red steadily. When the unit is not streaming, the LED lights amber steadily. If the unit is unable to stream (for

example all individual streams are disabled) the stream LED ashed RED rapidly.

• Stop – Press to stop the active streaming. When the unit is not streaming, the LED lights green steadily. When

streaming is paused, the LED lights amber steadily.

• Pause – Press to pause streaming. When pressed, the green Pause button blinks amber to indicate streaming is

paused. When streaming is paused, the LED lights amber steadily. Press Stream or press Pause to resume streaming

or Stop to halt the streaming.

NOTE: When paused, the last full frame of active video is held as a still image.

• Mask – Press

M ASK

to transition cleanly from streaming live video from the HDMI input to streaming a selected still image

mask. Press the button again to transition cleanly back to streaming video from the HDMI input.

Powering Up

When applying power, the unit undergoes a self-testing sequence. The power led starts blinking green when the power is

connected but the unit is still booting. The line of green LEDs in the input and output section of the front panel will light and the

streaming controls will light amber.

Streaming

The SME 211 supports unicast and multicast streaming protocols, including RTMP.

NOTE: The confidence stream on the web-based UI supports both audio and video.

To decode the streams:

To view the preview stream, go to the embedded web page AV Controls Panel. SME 211 streams can also be decoded using

an Extron SMD202 decoder or compatible third party players such as VLC and QuickTime.

Presets

Three types of presets are supported:

Encoder Presets – These presets allow quick switching between various encoder proles based on resolution and bit rates.

There are 64 encoder presets available.

Streaming Presets – These presets allow quick switching between various streaming proles. There are 16 presets for each

stream method that can be saved or recalled from the internal web pages.

Combined Encoding and Streaming Presets – These presets combine the features of both Encoding and Streaming Presets.
