Preface
Congratulations on your purchase of a Teledyne Benthos UDB-9000
Universal Deck Box! This portable (UDB-9000-M) or rack mount
(UDB-9000-MR) deck box combines all of the features of the Teledyne
Benthos DS-8750, DS-8000 and DS-7000 Acoustic Deck Sets and the
ATM-891 Acoustic Telemetry Modem Deck Box into one unit. This capability
enables the UDB-9000 to operate with all of the Teledyne Benthos acoustic
releases, transponders and pop-up buoys, and to operate with the Teledyne
Benthos acoustic telemetry modems, including Compact Modems. In
addition, the deck box operates with EdgeTech/EG&G and the University of
Rhode Island (URI) acoustic releases or with any transponder that replies to
pings in the frequency range 7–16 kHz. The deck box employs the same
digital processing technology used in the acoustic telemetry modems for
reliable wireless digital communications underwater.
This manual provides information on setting up and operating the
UDB-9000. It is divided into the following six sections:
Section 1 - Overview reviews the operational features, the operator
functions and the external connections provided by the UDB-9000.
Section 2 - Specifications lists the specifications for the UDB-9000.
Section 3 - Installation and Setup provides instructions on how to
unpack the UDB-9000, install the rack mount configuration in a 19-inch
rack and make the required connections.
Section 4 - Operation using the Touch Screen Display provides
instructions on how to operate all the functions of the UDB-9000 using
the touch screen display, including acquiring and displaying ranges and
sending commands.
Section 5 - Operation using Serial Interface Commands provides
instructions on how to send commands to the UDB-9000 and receive
round trip travel times and status information over a serial port using the
same command set and syntax as that used for the DS-7000 Acoustic
Deck Set.
Section 6 - Care and Maintenance provides recommended care and
maintenance procedures and a procedure on how to replace the
batteries in the portable configuration of the UDB-9000.
