2.3 Description
The HDE 200 cassette is used to feed standardised analogue audio and video
signals into 2 SPI data streams from completely different audio and video sourc-
es (e.g. audio and video reproduction devices, test picture generators, observa-
tion cameras etc.) . It is equipped with 2 stereo/audio inputs and 2 video inputs.
The video signals are supplied by a processor that encodes them in real time.
The stereo audio signals are transferred via an adjustable amplifier to the encoder
and are encoded according to the MPEG 1/ Layer II standard. The bit rates are
adjustable.
The cassette supports the D1 format (720 x 576 pixels) at data rates of
1.5…6Mbit/sec.Thesedataratesincludea16-bitstereoaudiochannel.
At the DVB-SPI output sockets (25-pin, SUB-D) a transport stream is provided accord-
ingtoISO/IEC13818forsubsequentprocessinginthe HDM 20x QMX cassettes.
The operating software of the cassette can be updated ("BE Flash" software)
using a PC or notebook via the 9-pin SUB-D socket. You can find the current
operating software for the cassette on the website "www.gss.de".
When the head end station is switched on, the two-line LC display briefly shows
the software version of the control unit and then the cassette type of the slot oc-
cupied first.
If no key is pressed for five minutes, the software version of the control unit is
displayed.
The cassettes are intended for use in the head end stations STC 316, STC 1200,
STR 19-8 and PST 19-1.

2.3.1 Software versions
Cassette
How to query the software version of the cassette is described in the "Selecting
the channel strip, displaying the software version" section on page 12.
Control unit
If necessary, you can activate the indication of the software version of the con-
trol unit manually:
•Pressanytwokeysonthecontrolunitoftheheadendstationsimultaneously
until the display goes dark and the software version, e.g. " V 41 ", is displayed.
3 Installation
3.1 Installing the cassette
Note
Before inserting or changing cassettes, pull the mains plug of the head end
station out of the mains socket.
• Screw the fastening screws 1of an unoccupied slot out of the bracket of the
head end station.
•Insertthecassetteinthisslotandpushitintothehousing.
•Alignthecassetteandapplyslightpressuretoconnectittotheconnectionsof
the board on the back of the housing.

3.2 Connecting the cassette
To comply with the current EMC regulations, it is necessary to connect the
lines leading in and out of the head end station (e.g. cinch, HF) using cable
terminals.
When mounting the cassette in an STR 19-8 or PST 19-1 head end station
which is installed in a 19" cabinet, make sure that the connections leading in
and out (e.g. cinch, HF) at the 19" cabinet are made using cable terminals.
•Inserttherequirednumberofstandardcableterminals(e.g.cinch,HF)inthe
openings provided (knock-outs) in the front of the head end station or the
19" cabinet. The cable terminals used are standard and are not included in
the scope of delivery.
Caution
Tighten the nuts of the cable terminals until the teeth on the lock washers put
under the nuts have penetrated the exterior coating and a good connection
is made between the housing and cable terminal.
Note:
– The following connection example show possible connection schemes.

Note:
The "RS232" socket (9-pin Sub-D) is for updating the operating software of the
cassette using a PC or notebook. Use the "BE-Flash" software as the update
software. You can find the current operating software of the cassette on the
website "www.gss.de".
