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 Y or coloured green or
green-and-yellow.
The wire which is coloured blue must be connected to the
terminal which is marked with the letter N or coloured black.
The wire which is coloured brown must be connected to the
terminal which is marked with the letter L or coloured red.

You are cautioned that any changes or modifications not
expressly approved in this manual could void your authority to
operate this equipment.

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
Transport Interface). This feature contributes to
increase of news gathering productivity.

(Serial Data

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.

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.

Error Messages

When a fault is detected by the self-diagnosis function
that automatically performs after the power is turned
on, all the indicators flash and an error message
(ERROR-XX) appears in the display window. The
indicators do not turn off until the power is turned off.

For more information about error messages, refer to the
Maintenance Manual.

Warning Messages

When a fault is detected while the unit is in operation,
the ALARM indicator lights up and a warning message
(0X WARNING) appears in the display window.
When the operation returns to normal, the ALARM
indicator turns off.

Use the list below to check the meaning of the warning
messages.
