1.2.2 Inputs
Transport Stream Input
The main input of the TT1220 is the QPSK f-connector, located on the rear
of the unit. This input interfaces directly to Low-Noise Block (LNB) and
accepts an intermediate frequency (IF) input in the 950 – 2150 MHz
(L-band) range. The unit can provide DC power, that may be used for
polarisation switching on the LNB, as well as a 22 kHz control signal. The
maximum input symbol rate is 44,5 Msym/s, while the maximum total
bit-rate is 60 Mbit/s.
An optional (factory fitted) DVB-ASI BNC connector may be present,
replacing the QPSK f-connector. This input accepts a DVB-ASI compliant
signal (188 or 204 byte), at a maximum of 60 Mbit/s.

4.1 Remote Control
4.1.1 Introduction
The TT1220 can be remotely controlled in a variety of ways. The basic
control methods are:
• RS-232 control methods:
• TDC (TANDBERG Device Controller)
• TSM (TANDBERG System Manager)
rd
• 3
• Over the air control methods:
• NDS Director
Common for all control methods is that the TT1220 needs to be set up to
accept the remote control handling. Once in remote control mode, it
cannot be locally controlled unless the remote control is deactivated.
4.1.2 Remote Protocol Control Documentation
The protocols used for remote control are the TANDBERG RS-232 control
protocol and the NDS Director Over-the-Ai r control protocol. Neither of
these protocols are described, or i n tend ed to b e i n the scope of this
manual.
party application (using TANDBERG RS-232 control protocol)
For information about these protocols, please refer to the remote control
documentation, or contact TANDBERG to obtain this information.
NOTE…
The remote control protocols are not contained as a part of the product. An additional license fee, NDA
or other agreement with TANDBERG and/or NDS may be necessary to obtain the information required
to control the product remotely.
4.1.3 Configuring the Unit for Remote Control Via RS-232
For the unit to be controlled via RS-232, the RS-232 port has to be
configured to the same settings as the host controller system. The control
mode of the TT1220 also needs to be set to remote.

4.1.5 OAC Lockout
Overview
Once the unit is in OAC control mode, it is possible for the remote control
operator to issue a local lockout command to the decoder. This will
effectively deny the local user access to configuring the unit.
However, if a situation occurs whereby the local user needs to regain
control over the unit, without a local lockout relinquish command being
sent from the OAC control PC, a four digit PIN may be entered through the
keypad.
The PIN is created at lockout time by the user. To obtai n the PIN, p lease
consult the person responsible for the administration of the unit.

C.1.1 Using the Menus
Detailed description of the use of menus is given in Chapter 3, Operating
the Equipment Locally.
C.1.2 Menu Descriptions
This annex describes the front panel LCD menus.
When the unit is first powered up, it progresses through a series of
start-up pages on the LCD display.
The menu is created in a tree structure, where each branch may contain
items, new branches, or both.
An item is viewed as an information string on the left side of the LCD, with
an editable or selectable item on the right side, or an information string.
A path to a new sub branch is viewed as an information string on the left
side of the LCD, where the string ends with a “>” character. The “>”
symbolises the arrow key you have to press, to enter the submenu.

the encoder.

The Left output and Right output columns refer to the output at the left

the left and right audio signal present in a stereo transport stream. “1”
and “2” refers to the audio signals in channel 1 and 2 respectively (the two
mono signals present in the Dual Channel audio PID), or 1 for a mono PID.
As seen from the table, Dual Channel PIDs will only provide both channels
to the user if modulation is set to “transparent”. This could for instance be
very useful for a two language service, where each language is sent as a
mono component in a dual channel PID. In both the stereo and mono
configurations, a dual channel PID will only provide one of the audio
channels to the users.
This channel is selected to match the “Aud Lang” setting set up in the TV
Components Menu (see Table C.5). If the language setting does not match
any of the two audio components in the dual channel stream, the first one
will be selected and decoded.
