First aid: artificial breathing(mouth to mouth)
1
In case of electric shock you have to ensure the first aids
to the patient, but to do this you have to consider two very
important things:
- interrupt immediately the electric circuit;
- if the circuit has not been interrupted, do not touch
the patient with bare hands;
After doing this, without delay contact the nearest mobile
unit of first aid and practice to the patient, in case of loss
of consciousness, the breathing mouth to mouth as
described below.
2
Put the patient lying on his back with the arms parallel to
the body, ensure that he does not have the breathing
tracts obstructed (chewing-gum, dental prosthesis, etc.),
otherwise set him free from foreign bodies.
Kneel near the patient’s head and putting a hand under his
neck, incline as possible his/her head backwards.
3
Going on with keeping the patient’s head inclined with one
hand, use the other one to occlude the nostrils, if you are
going to practise the breathing through the oral cavity, or
occlude the mouth if you want to do it through the nasal
cavity.
While doing this begin the auto-oxygenation, with deep
breathing.
Then practice the artificial breathing blowing in the chosen
cavity beginning with ten expirations each minute to go on
them with twelve and fifteen.
4
During the breathing procedure you have to control that
the patient’s chest dilates, otherwise change cavity where
to blow the air because the previous one could be
obstructed.
5
Do not ever stop the artificial breathing until the patient
has recovered or the first aid unit has come.

1. GENERAL INTRODUCTION
The EK-ENR/2 card is a double audio/video encoder.
It is able to encode up to 2 video and 4 audio in a single output transport stream.
This card must be used in an EK-MFR/x mainframe in order to configure it in the right way.
The input/output connectors (figure 1) are on the back of the board and basically you have:
4 SFP connectors with input/output capability used for transport stream (SFP1, SFP2) and SDI or
analog video (in default configuration you have SFP3 for SDI video and SPF4 for analog video)
1 RJ-45 connector used for analog and AES3 audio
Figure 1 –EK-ENR/2 Input/Output connectors
The video input can be in SDI or analog format, with SD or HD resolution and it is encoded conforming to
ISO/IEC14496-10 (H.264/AVC) standard.
The audio input can be sourced from SDI embedded, analog or AES3 signal and it is encoded conforming to
MPEG-1 Layer 2 standard.
The output transport stream is conform to ISO/IEC 13818-1 standard and it is present in ASI standard
electrical format on the SFP1 and SFP2 connectors.
The transport stream can also be output through the mainframe’s internal matrix in order to feed another card
(i.e. the EK-UNM/3 modulator) without using an external cable.
In figure 2 you can see the EK-ENR/2 block scheme.

In the EK-ENR/2 block scheme (figure 2) you have in red the card menu voices that you have to use in order
to set the card functionality (see chapter 2).
In the figure 2 you can see:
the video encoder input selector that allows you to feed the video encoder with the signal coming from
the SFP3, the SFP4 or with a test signal (see 2.2.2, 2.2.14)
the audio encoder input selector that allows you to feed the audio encoder with the signal coming from
the analog input (on RJ-45), the AES3 input (on RJ-45), the SDI audio embedded, with a test signal or
with a “mute” (see 2.2.7, 2.2.19).
the two H.264 video encoders
the two MPEG-1 layer 2 audio encoders
the output mux that allows you to multiplexer the encoders output TS in a single TS (see 2.3.1).
The output selector that allows you to choose which TS put out (see 2.3.2, 2.3.3, 2.3.4)
The EK-ENR/2 is a flexible and highly configurable system.
You can work with both SDI or analog video signal and SDI embedded, analog or AES3 audio signal.
The output multiplexer togheter with the Enable/Disable capabilities for the single encoder allows you to
“build” the output TS with different combinations (1video+1audio, 2video+2audio, 1video+4 audio, see 2.3.1).
The PCR and audio clocks are locked to the input video clock.
In table 1 you can see the main characteristics of the EK-ENR/2.
Remember that in the standard configuration the EK-ENR/2 is supplied with:
one electrical interface for SDI signal on the SFP3
one electrical interface for Analog signal (PAL/NTSC) on the SFP4
For the audio connections please contact Eurotek for RJ45-to-XLR solutions.

2. BOARD MENU
The EK-ENR/2 card may be configured by means both the EK-MFR/x keyboard or the MST Eurotek Software
Suite, a PC based application (in the latter case you have to connect the PC via Ethernet to the EK-MFR/x).
In both cases the configuration is based on a number of variables that you can modify and that allow you a
deep control over the card features.
These variables make the “card menu” and they are summarized figure 3.
In this figure you can see that there are 4 main menus:
Status: here are reported the “read only” variables that show the status of the card (ie video state,
temperature, an so on). See chapter 2.1.
Settings: here you can find the “read/write” variables that allows you to modify the encoder
functionality (ie enable/disable encoder, change the encoder bit rate or pid). See chapter 2.2.
Set Output: in this menu you can change the output multiplexer bit rate and decide which TS send to
the SFP output and to the internal output. See chapter 2.3.
Revision: here are reported the software versions of the card. See chapter 2.4.
From the keyboard you can easily scroll through the menu by means the Up/Down and Enter/Esc buttons and
change the values of the read/write variables with the same buttons.
From the MST software you can directly change the read/write variables writing the new value from the PC.

2.1 STATUS MENU
In this menu are reported the “read only” variables that show you the state of the card.
Some variables may generate alarms when they go out of the boundary (ie too high temperature).
These alarms are reported on the screen of the mainframe and in the log alarm file (you can read this file by
means the MST Eurotek Software Suite).
Below are explained the Status menu variables.
