2.1.1.2 24 VDC Power Supply

The 24 VDC Power Supply inputs switched AC power from the Computer Power Supply to generate +24
VDC which is output to the Powerboard

2.1.1.3 Computer Power Supply

The Computer Power Supply switches AC power to the 24 VDC Power Supply and provides DC power for
the CPU Board and the hard drives.

2.1.1.4 ADSL Modem

The ADSL Modem board converts the uplink data ADSL signals received from the tow vehicle and input on
the ADSL connector from the Power board into Ethernet 10/100BaseT signals, which are output through
a direct connection to the Ethernet port of the CPU board. Similarly, the ADSL Modem board converts the
downlink Ethernet 10/100BaseT based command signals from the CPU board into the ADSL downlink
command signals, which are output on the ADSL connector to the Powerboard for transmission to the
tow vehicle. The ADSL Modem board also serves as an Ethernet switch to provide an Ethernet connection
on J1 to the Net Burner board on the Power board, placing the Net Burner board on the same local area
network (LAN). +12 VDC power is input on the DC connector from the Powerboard.

2.1.1.5 Net Burner

The Net Burner board mounts and connects directly to the Powerboard to provide Powerboard
diagnostics, tow vehicle power control, positive and negative trigger edge selection, and sensor
monitoring. An Ethernet connection to the Net Burner board is provided on J3 from the ADSL Modem
board. Power is input from the Powerboard.

2.1.1.6 Central Processing Unit

The Central Processing Unit (CPU) board runs the Windows 10 operating system and EdgeTech's Discover
software. The CPU board outputs downlink commands to the tow vehicle over the Ethernet connection
to the ADSL modem board. At the same time, it inputs the uplink sonar data from the tow vehicle over
the same connection. A 500 GB hard drive contains the operating software, and a 2 TB hard drive is used
for data storage. Both hard drives interface with the CPU board, as do the monitor, keyboard, and
trackball. The Computer Power Supply provides power to the CPU board.

2.1.1.7 Hard Drives

A 500-GB hard drive (C:\ drive) stores the Windows 10 operating system and the application software. A
removable hot-swappable 2TB HDD is used for data storage.

2.1.2 4200-P Portable Topside Processor
