5.2 SP-III TPU
The SP-III TPU provides signal processing along with the system control and data
telemetry functions. The printed circuit boards, along with their corresponding part
numbers, are the following:
• Demux board 14105208-04
• CPU board 14105873
• Topside Telemetry board 14105646-02
• Power Integration board 14105210-02
• Panel Interconnect board 14105209
• Power Supply 11700094
• Fan 14105343
All of these components are shown in Figure 5-4, and a block diagram of the
SP-III TPU electronics is shown in Figure 5-3.
Demux board.
The Demux board functions as a data and power interface
between the towfish and the CPU. DC power and telemetry commands are
transported down to the towfish, while sonar and sensor data transported up
from the towfish are decoded and passed along to the CPU.
CPU board.
The CPU board functions as the command and data interface
between the laptop computer running SonarPro and the tow fish. It executes a
real-time data server which outputs sonar and sensor data to and receives
commands from an external client, such as SonarPro.
Topside Telemetry board.
The Topside Telemetry board provides the cable
interface for the SP-III TPU. Specifically, the Topside Telemetry board
performs the following functions:
• Separates the uplink data signals, the downlink command signals and the
towfish power.
• Acquires sonar and sensor data and reformats the data as required for the
Demux board.
• Generates command and timing signals for the towfish.
• Matches the time references at the tow fish and the SP-III TPU.
Power Integration board. The Power Integration board provides 200 VDC to
the towfish from either a 12 VDC or a 88–264 VAC, 47–63 Hz source. It also
provides filtering, reverse polarity protection, and fusing of the input power.
Panel Interconnect board.
The Panel Interconnect board facilitates a simple
mechanical cable interface to the various external connectors in the system.
