The unit, based on the SIPS
2 XSRS, is specifically designed to mount on or under a
tailbuoy with its power supplied by the tailbuoy battery
instead of the XSRS battery pack.
The unit is available in
several different variants, including right-angle or remote
transducer and can be fitted with either AGP or AGM connectors.
Once fitted to a tailbuoy
the software requires only a simple change of device number
to enable the tailbuoy transceiver unit to become operational.
Power is supplied to the
unit via a standard 4 pin AGP or AGM connector at 12 - 60
volts DC. Communications, which are taken from the streamer
coil circuit, also run through this connector.
Each receiver is capable
of receiving 1 of 60 unique digital signals. The use of
digital acoustic signals and digital processing techniques
enable the XSRS to transmit and receive signals in the same
event. In addition, they are able to transmit and receive
SIPS 1 style tone burst for cross wake ranges.
