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 211The 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 ConnectionsThe 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.

B 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.

F 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.

Input Connections

C HDMI input – Connect an HDMI (or DVI with a suitable adapter) source device to input.D 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 figure 2.

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 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 fixés dans le connecteur et pourraient être tirés.

Output Connections

E 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.

commands to the SME 211 for device configuration 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.

D USB storage port – Connect a USB compatible media device to this port. The device can be any standard external hard drive or USB flash drive formatted with a compatible file system, or a mouse or keyboard for network setup. Compatible formats include FAT32, VFAT, and NTFS.

E 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.

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

G 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.

H 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 flashed 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 MASK 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 profiles based on resolution and bit rates. There are 64 encoder presets available.

Streaming Presets – These presets allow quick switching between various streaming profiles. 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.
