    Marine construction surveys Main System Components The 2000-TVD system is composed of two main components: a 2000 rack mount topside and a 2000-TVD towfish. The rack mount topside includes a computer and a STARMUX III digital telemetry link installed in a 19-inch rack enclosure, along with a keyboard, a trackball, and two LCD monitors.

  • Page 20: Topside Computer

    The computer can also interface with a user-provided printer (see 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.

    3 kHz means that self-test has failed. These tones are generated in software in the towfish and replicated on the surface when an EdgeTech topside computer is used to access the Towfish computer subsystem using the Remote Desktop application. The Self-Test PASS tones repeat until data linkup has occurred between the topside DISCOVER software, and towfish.

    Data throughput rates on the uplink (vehicle to topside) can be critical in getting smooth data from the towfish. The data throughput rate can be checked using EdgeTech supplied utilities at each end of the link The SockBlast application is used to test network throughput between the towfish and the topside computer.

    6-11 6.3.8 Tow Cables Historically, most system problems occur in the tow cable and their connectors. Before proceeding, verify cable continuity from the shipboard end of the cable to the towfish. The presence of a shorted or open wire in a tow cable can be determined by using a multi-meter. An open or shorted wire can be located using the techniques described in the following subsections.
