4200 SIDE SCAN SONAR SYSTEM USER HARDWARE MANUAL 0004842_REV_N
1.3.1 Topside Processors
Each of the three 4200 Series Topside Processor options provides downlink telemetry to the tow vehicle
for sonar control. They also receive up-link side scan data, sensor data, and status information from the
tow vehicle for processing, storage, and display. Each topside processor interfaces with a tow vehicle over
a 10/100BaseT connection, using asynchronous digital subscriber line (ADSL) modems in both the tow
vehicle and the processor. The three available types of 4200 Series Topside Processors (shown in
F
IGURE 1-2) are listed below:
• 4200 Rack Mount Topside Processor
• 4200-P Portable Topside Processor
• 701-DL Digital Link
The 4200 Rack Mount and 4200-P Portable Topside Processors each include a computer with Windows 10
and EdgeTech Discover Side Scan Sonar software preinstalled. The 701-DL Digital Link is used for
applications where a user-supplied computer running Discover or third-party data acquisition and display
software will be used.
1.3.1.1 4200 Rack Mount Processor
The 4200 Rack Mount Topside Processor is intended for permanent mounting in a sheltered section of
the survey vessel.
The processor includes tow vehicle and DC power supplies, a computer with preinstalled Windows 10 and
Discover Side Scan Sonar software, an ADSL modem, and an Ethernet switch, all within a single 19-inch
4U rack. The system also comes standard with a keyboard, trackball, LCD monitor, DVD/RW drive, 2-TB
hard drive for data storage, and a 500-GB hard drive for the operating system. An optional printer can be
connected to the system.
1.3.1.2 4200-P Portable Topside Processor
The 4200-P Portable Topside Processor is enclosed in a watertight (when closed) shell and comes with the
added convenience of allowing the user to re-locate their system as needed.
The processor includes tow vehicle and DC power supplies, ADSL modem, Ethernet switch, and a wireless
router, all within a single, compact, rugged, and watertight (when closed) enclosure. The system also
includes a semi-rugged standard or optional rugged laptop computer with preinstalled Windows 10 and
Discover Side Scan Sonar software. The 4200-P runs on either AC or DC power and interfaces with the
computer over a wired or wireless 10/100BaseT Ethernet connection. The computer can be stowed inside
the 4200-P enclosure when not in use.
