1. Introduction
The Tritech 72V VDSL Adapter Unit is designed to provide long length
power and communications for the Tritech International Ltd range of Gemini
products.
The Adaptor Unit is powered from a standard Mains power supply and
communicates to a control PC via Ethernet. Power to the connected Gemini
device can be controlled by an external power switch.
The Adaptor Unit can be used to communicate with Gemini Sonars on cable
lengths up to 300m. This cable length can vary depending on the specific
characteristics of the cable used. Appropriate Cabling can be purchased from
Tritech International Ltd, with prices and lead times available upon request.
The Adapter Unit is fully compatible with all versions of the Gemini Software
and versions of Seanet Pro that support the Gemini range of products.

3. Installation
!
Caution
Although the 72V VDSL Adapter has a rugged design care should
be taken during installation and de-installation. The connectors can
be damaged if forced, or if the wrong cable is plugged into the
wrong connector.
The 72V VDSL Adapter should be used with the appropriate umbilical capable
of sustaining VDSL communications over a long cable length. Contact Tritech
International Ltd if more information is required.
Note
The signal path should have a characteristic impedance of 110Ω
(±10Ω) for the entire cable run for optimal performance. Cabling
that deviates from this will result in reduce range capability for the
VDSL signal.
!
Caution
The 72V VDSL Adapter unit needs to be connected to an Earth.
Before powering up, ensure that the mains socket being utilised
has a proper connection to Earth.
When connecting a Gemini and PC to the 72V VDSL Adapter follow the steps
below.
• Ensure that the Sonar Power switch button on the 72V VDSL Adapter is
set to its OFF position
• Connect the subsea connector end of the umbilical to the Gemini
• Connect the surface connector end of the umbilical to the 72V VDSL
Adapter
• Connect an Ethernet patch cable to the Ethernet port of the 72V VDSL
Adapter
• Connect the Mains cable to the 72V VDSL Adapter and plug into an
appropriate mains socket
The unit will now be ready to power on. An example of this setup can be seen
in Section 3.3, “An Example Setup”
!
Warning
The 72V VDSL Adapter must never be opened when connected to
the Mains supply, even if both the Sonar Power switch and Mains
switch are off.
