For the customers in the United Kingdom
WARNING
THIS APPARATUS MUST BE EARTHED
IMPORTANT
This wires in this mains lead are coloured in accordance with
the following code:
Green-and-yellow:Earth
Blue: Neutral
Brown: Live
As the colours of the wires in the mains lead of this apparatus
may not correspond with the coloured markings identifying the
terminals in your plug proceed as follows:
The wire which is coloured green-and-yellow must be
connected to the terminal in the plug which is marked by the
letter E or by the safety earth symbol Yor coloured green or

Features
The DSM-T1 Digital Satellite Modulator modulates
analog video and audio input signals into digital
signals. This modulator enables an SNG (Satellite
News Gathering) system in combination with the
DSM-R1 Digital Satellite Demodulator.
The following are some of the features of the DSM-T1.
Easy Installation
The DSM-T1 provides easy connection with an
existing SNG system via IF OUT (Intermediate
Frequency output).
High quality compression algorithm
MPEG2 4:2:2 profile at Main Level (4:2:2 P@ML)
ensures superior picture quality at 18 MHz
transmission bandwidth.
Direct digital transmission at up to twice
real time
The DSM-T1 enables transmission at up to twice real
time speed at 36 MHz transmission bandwidth with
connection of a DNW-A100/A100P digital video
cassette recorder through the SDTI 1) (Serial Data
Transport Interface). This feature contributes to
increase of news gathering productivity.
Optional interface boards available
The BKSM-T101 SDTI Input Board, the BKSM-T102
SDI Input Board, and the BKSM-T103 Analog Input
Board provide flexible choices of installing one or two
boards to this unit.
Two-program Transmission
Two multiplexed video and audio signals can be
transmitted simultaneously at 36 MHz transmission
bandwidth. This contributes to lower transmission
costs.
1) SDTI is defined as SMPTE 305M.

Connection
The illustration below shows a typical connection of
the unit for digital Satellite News Gathering.
• There are two kinds of connectors on the BKSM-T103
Analog Input Board, 3-pin XLR or 5-pin XLR connector.
When using the 5-pin XLR connector, see also the next
page.
• For more information about connecting external
equipment, refer to the equipment operation manuals.

Setting a password
If the PASSWORD is set to “ON” in the menu, set a
password for the unit so that it matches that of the
DSM-R1. If the password of the unit does not match
that of the DSM-R1, the “PASSWORD
INCORRECT” warning message appears in the
display window of the DSM-R1 and no audio/video
signals are output from the DSM-R1.
If the PASSWORD is set to “OFF” in the menu, the
DSM-R1 outputs the audio/video signals regardless of
the password of the DSM-R1.
For more information, see “Menu Setup” (page 10).
