3.4 Extended configuration (individual settings)
The configurations explained so far suffice for the intended use of the EMA device to generate transport streams in conformity with DVB.
There are further options possible for professional use with special functions.
3.4.1 TTX processing/ VPS/ WSS
These configuration settings control how teletext information contained in the analogue signal will be adopted and the VPS and WSS
control signals will be captured, processed and forwarded in the transport stream.
The following settings and functions are possible:
Switches

Function
TTX processing
OFF
No teletext or VPS and WSS data adopted.
TTX processing
Video-IN
Teletext data from lines 7 to 15, 19 to 22, 320 to 328 and 332 to 335, will digitalised and
transmitted in the DVB transport stream.
TTX processing
Video-IN
Teletext data from lines 7 to 15, 19 to 22, 320 to 328 and 332 to 335, will digitalised and
transmitted in the DVB transport stream.
In addition, VPS, WSS or VPS+WSS (depending on what has been selected) will be
digitalised and then transmitted as part of the DVB transport stream.

3.4.2 Options
Adaptations or options supplied to customer specifications may be charged for.
3.4.3 Firmware updates (emergency program)
If a firmware update becomes necessary, a Windows update program will be made available. The update will be carried out either
via the Ethernet interface or via the (RS232) control interface on the EMA device. For this purpose the computer and the EMA device
must be connected to each other by means of either an Ethernet cable or a null modem cable (cross-linked cables in each case).
After the program has been opened, the computer interface to be used must be selected in the update window. If the right interface is
selected, the “Upload” button will be activated, allowing the update to be started with this button.
Firmware updates do not change any parameters already set (whereas the opposite is true of using the recessed “Factory setting” key,
which restores settings to what they were on delivery of the device).
3.4.4 Re-set to status on delivery (Factory settings)
The following 3 possible ways of restoring the status on delivery:
A. Factory setting using the user software (HTML page):
This will only be possible if the IP configuration for the device is known, including network address subnet mask, and the device can be
contacted via the Ethernet interface. The Internet browser should be used as described in section 3.3.2 (“Connecting the network to
the computer”) to access the device operation system. When the access data have been entered, the configuration menu will appear.
The “Factory Setting” box is displayed in the menu header. If this box is clicked, all the parameters for the device which are capable of
configuration, excluding the IP address (!), will be reset to those for the state the device was delivered in, and the device will be restarted.
A
reset of the IP address
to the default value is proceed as described in
section B
.
B. Factory setting using the “Factory Set“ key (on rear of device):
In order to re-set all configurable parameters
including the IP address for the device
so that they are as delivered, this key must be
activated for at least 5 seconds, until all the LED‘s on the front flash at the same time. The flashing LED‘s are the confirmation that the
factory set function has been carried out. When the key is released, a new start will follow automatically in which the parameters are as
reset. After changing the IP address the connection to the device is invalid and thus interrupted. To restore the connection, the steps in
section 3.3.1 (“Network connection to the computer“) are processed.
C. Factory setting with the aid of the maintenance software (via RS 232):
The maintenance software is a Windows PC program module obtainable from BLANKOM systems GmbH which will create the
factory settings. Firstly, the maintenance software has to be installed on the control PC and a cable connection must be established
between this and the EMA device. The cable must be a null-modem cable. When the program has been started and the various
procedu-res run, the EMA device is restarted with all parameters reset.
If B or C is used, the IP address of the EMA device after reset is: 192.168.2.86 with the subnet mask 255.255.255.0.
