9. Tow Cable The 4125 Series Dual Frequency Side Scan Sonar System includes a 50 meter tow cable terminated at both ends The tow cable is used to connect to and tow the tow vehicle and is either a Kevlar reinforced six conductor or an RG 58 coax cable which includes a single conductor and a shield The coax cable is used only for systems that include the additional telemetry option Up to 150 meters of six conductor cable or 600 meters of coax cable can be used Contact Edgetech Customer Service for available cable lengths other than the supplied 50 meter cable A cable grip is also included for attaching the tow cable to a shackle on the towing arm of the tow vehicle 1 6 SECTION 1 Overview 1 4 Optional Equipment Optional equipment that can be installed and used with a 4125 Series Dual Frequency oide Scan Sonar System include the following Additional telemetry Keel Weight Kit specified when ordering tow vehicle p n 0008464 HullScan Kit W O Telemetry Depressor Wing Kit p n 0007860 p n 0008478 HullScan Kit W Telemetry p n 0008477 1 4 1 Additional Telemetry The additional telemetry option increases the maximum length tow cable that can be used from 150 meters to 600 meters by using VDSL modems to establish the communications link between the tow vehicle and the topside processor instead of a direct Ethernet connection 1 4 2 Wing Kit The Depressor Wing Kit provides a depre

Add the measurements in Step 4 and 5 above subtract the measurement in Step 2 and divide the result by 2 Rs 7 Subtract the value in Step 6 the measurements in Step 4 and 5 R1 R2 8 The distance to the short from end 1 is the ratio of R1 R1 R2 times the total cable length Recheck from end 2 which is R2 R1 R2 times the cable length Locating an Open Conductor An open conductor in a tow cable is much more difficult to locate than a short therefore a capacitance bridge is recommended Measuring the capacitance from the open conductor to the shield on both ends allows two different capacitance readings to be recorded This represents a direct ratio related to cable length and distance of break from each end Before cutting the cable double check the same ratio of capacitance using an adjacent good conductor in a multi conductor cable Capacitance may vary from conductor to conductor depending on their separation 5 16 SECTION 5 Maintenance and Troubleshooting Most breaks occur around the tow cable termination or where a previous repair has been made A cable break may be found or confirmed by laying out the cable and attaching an ohmmeter across each end of the open conductor Then flex the cable first near the termination or repaired section and then along its entire length until the break is reached When flexing the ends of the broken conductor may touch giving a continuity reading on the meter 5 8 3 Locati

22. 1 Overview 1 1 The EdgeTech 4125 Series Dual Frequency Side Scan Sonar System is a frequency modulated FM dual frequency side scan sonar that uses EdgeTech s proprietary Full Spectrum chirp technology to generate high resolution side scan imagery at longer ranges than conventional continuous wave CW systems The system is designed primarily for search and recovery operations and surveys in shallow water The 4125 Series is available in two dual simultaneous frequency configurations depending on the application 400 900 kHz and 600 1600 kHz For shallow water survey applications the 400 900 kHz frequency set is the best choice as it provides an ideal combination of range and resolution For ultra high resolution imagery at shorter ranges the 600 1600 kHz set is the recommended choice In both configurations the frequencies are transmitted as linearly swept wide band high energy acoustic pulses and the received echoes are processed into high signal to noise SNR images which can be directly displayed as shades of gray or color on a computer monitor and printed on a continuous feed thermal printer The data can also be stored in real time onto a large capacity hard drive and archived onto a DVD Company Background EdgeTech formerly EG amp G Marine Instruments traces its history in underwater data acquisition and processing back to 1966 EdgeTech has designed developed and manufactured products instruments and systems for the acqu
