ENG

6- The software will install all the driver, dll and all the things necessary for the installation. A

reboot is necessary after the installation (and suggested)

ENG

Warning! The installation procedure must be done with only ONE “Streamer” at the time

2 Installation of STREAMER RX

Plug the network cable into the network port of the “Streamer RX” device and the other end into your hub or switch.

Plug the jack of your earphone into the headphone output.

Plug the power supply into the power jack of the device and the other end into the power outlet of the wall.

After few seconds, will play a typical sound if a network is founded.

To verify the IP address assignement and manage the other parameters of “Streamer” you can use Streamer Control software. Install and running Streamer Control. Verify that no firewall is active into your PC.

The active parameters of the “Streamer” that you selected, will be showed into EEPROM and RAM column. Now you can test the decoder audio function using UDP Streaming Test utility. By clicking on the START button of UDP Streaming Test there will be the streaming of an audio MP3 file to the IP address of “Streamer” select

ed. The suond will be played through the headphone and the RCA

pin (“Streamer” only, not “In-Streamer”). The audio parameters, like volume, bass, treble and loudness can be changed via the Audio setting. The streaming will stop at the end automatically but yuo can stop it in any moment by pressing the STOP button.

DHCP NOT FOUND

message will appear on the top of

form this means that any DHCP

server is present in your network and that any IP address has been assigned to “Streamer”. Therefore, IP values of “Streamer” have to be assigned manually. We suggest to chose carefully

your IP address or to contact you network administrator to avoid any conflict with other network

devices.

To set manually the parameters of “Streamer” you have to select the device in the list box. After the Warning messages you will be ready to assign the network values to “Streamer”.

Selecting the “Streamer” device will show you the new network parameters. As you will see the

EEPROM parameters will be transferred to RAM column. This means that your “Streamer” can be

reached on the network through the new IP value stored.

Now you can test the decoder audio function using

utili

ty. By clicking on the

START button of UDP Streaming Test there will be the streaming of an audio MP3 file to the IP

2 How To Decode Audio Streaming With “Streamer RX”

For installation and configuration refer to Chapter 1

To manage the decoding parameters of “Streamer” you can use

Streamer Control

Verify that no

firewall is active into your PC.

Pushing

Get List !

button,

you will see as follows

“Streamer” device

ENG

By clicking on device inside the list box all the parameters of the item selected will appear. Now you can set the decoding parameters.

Streamer RX can decode only UDP streamings. To decode an UDP audio streaming you have to press the UDP button into “Streamer RX” decoding setting section. Then “ANNOUNCEMENT (UDP mode)” message will be displayed in the right window. If a streaming is addressed to the multicast or unicast IP address of “Streamer RX” this will decode it immediately. Depending on the network traffic, it could be necessary to set the “Streamer RX” buffer delay (values admitted from 0 to 500 ms). If you want to decode a TCP streaming you have to mount the memory option on the “Streamer RX” board by upgrading it into Streamer RX version.

You can check the “Streamer

RX” proper decoding by the

UDP Streaming Test.

By pressing the

START button a short mp3 file will be sent to the “Streamer RX” selected. You can also check the right audio decoding of all the “Streamer RX” devices on the network simply by pressing Get List ! followed by START button: the same short mp3 file will be sent to the default “Streamer” IP multicast address.

During playback you can set volume, bass and treble level and choose either to activate or not the loudness of the “Streamer RX selected”. All the values will be stored in the “Streamer RX” EEPROM. You can also reset to default values the audio parameters by pressing Reset button.

3 How To Encode Audio Streaming With “Streamer RTX”

For installation and configuration refer to Chapter 1

To manage the encoding parameters of “Streamer” you can use

NS1 Tools

software.

Verify that no

firewall is active into your PC.

Pushing

button

, you will see as follows

“Streamer XX” device

ENG

By clicking on device inside the list box you will have all the parameters of the item selected. Now you can set the encoding parameters.

The parameters neededs to start to encoding are:

IP Address

unicast or multicast IP address of “Streamer” player/s targets

Port:

destination port of “Streamer” player/s targets. All the “Streamer” models are ready to receive the streaming throught 6244 port.

Frequency:

audio sampling frequency.

Channels:

mono or stereo mode. If you choose to use the microphone input remember to use the 1 channel option.

Bit Reservoir:

to improve the streaming audio quality it have to set on 0

Quality:

The encoder uses Variable Bitrate Encoding (VBR) to realize optimal compression of the audio data. The setting of a fixed bitrate is replaced with setting a quality level that preserves audio quality in critical sections and enhances compression otherwise. The minimum bitrate (in case of digital zero samples) is 32 kbit/s for MPEG 1 and 8 kbit/s for MPEG 2. The maximum bitrate is 192 kbit/s for MPEG 1 and 160 kbit/s for MPEG 2. The following table gives an overview on the average encoding bitrate that can be expected for common audio signals at different quality settings and sample rates.

General Purpose Input Output (GP Option)

The Streamer and InStreamer equipment allows 2 General Purpose (GP) Input and Output. The GP name are GPI6 and GPI7 for the inputs and GPO6 and GPO7 for the output

GPInput

In order to activate GP6 and GP7 inside Streamer, place directly on ground the “In” signal ( IN to GND) as shown in picture.

It is already possible employs both connectrs GND. Please remember that IN and GND are directly connected to µProcessor (µP) equipment. Pay attention to don’t connect external voltage to this connectors. These connectors can be directly applied to Axel Technology equipments as BOBCAT and BoxRelè, already made in order to manage all kind of signals coming from CD player, MD Player, tape recorder, ISDN tunneling or Automation System.

GPOut

Inside InStreamer are presents two BiStable Relay, iIn order to employ the GPOut. These Relays allows TWO condition: NC and NO.

NC = Normally Close NO = Normally Open C = Common Contact

Details: When there are no activation in GPI the Relay contact stay on NC. When GPI become activated, the output relay change the contact closure versus NO, as showed in picture. In the example figure, a cc generator is connected in the common contact and the same point directly to LAMP1 and LAMP2. In GPI non-activation position, LAMP1 is ON, and LAMP2 is OFF In GPI Activation position, LAMP1 is OFF, and LAMP2 is ON Working votage = 5 Vcc Maximum Voltage (breakdown) = 100 Vcc
