1.2.1 Topside Computer
The topside computer is a PC contained within a ruggedized 19-inch 4U chassis. It controls the towfish's
sonars and processes, stores, and displays received side scan and sub-bottom data, as well as sensor data
and status information. A keyboard, a trackball, two LCD monitors, a DVD/RW drive, a 1-TB hard drive for
data storage, and a 500-GB hard drive for the operating system are included with the topside computer.
The computer can also interface with a user-provided printer (see
B.0: PRINTERS ).
The topside computer interfaces with the STARMUX III over a 10/100/1000BaseT Ethernet connection,
and includes EdgeTech’s DISCOVER 2000-C Dual Frequency Side Scan Sonar software and DISCOVER Sub
Bottom software preinstalled, along with the Windows 7 operating system.
1.2.2 STARMUX III
The STARMUX III digital link provides power for the towfish, while acting as an interface between the
topside computer and the towfish. The STARMUX III provides downlink telemetry to the towfish for sonar
control and receives uplink side scan and sub bottom data, sensor data, and status information from the
towfish. Interfacing with the topside computer over a 10/100/1000BaseT Ethernet connection, the
STARMUX III includes both towfish and DC power supplies, an asynchronous digital subscriber line (ADSL)
modem, and an Ethernet switch, all within a single 19-inch 2U chassis.
