Verifying that all CS90 cables are properly connected
The CS90 relies on communication between each system unit, and between the CS90 and external devices. It is very important that all cables are correctly installed, that the proper cable types have been used, and that all cables are connected correctly.
Prerequisites
Before you can do this task, the following prerequisites must be met:
•  The CS90 is installed as specified in this manual.
•  All system cables are installed.
•  All cable connections are made, except:
–  AC power cables
–  Transducer cable
You need the following equipment:
•  Cable tester
•  Multimeter
Context
All cabling is described in the Cable layout and interconnections chapter. Refer to the cable plan, the cable list and the basic cable requirements.
Procedure
1 For each cable that is in used on the CS90:
a Make sure that the cable has been installed as specified in the Cable layout and interconnections chapter.
Note
Pay special attention to signal cables. These must not be installed too close to power cables.
b Make sure that the connections made at each end of the cable are correct.
c Make sure that the cable is properly identified.
2 Make sure that the transducer cables can move freely when the transducer is lowered and hoisted.
3 If possible, use a multimeter or a dedicated cable tester to check the continuity in each cable.
4 Use a qualification tester to verify that each Ethernet cable is correctly wired, and meets the specifications related to quality and bandwidth.
5 If irregularities are found, write these down in the in the Installation remarks table.
Result
Requirements Results
Each cable is installed correctly.  
All relevant cable connections are made.  
Each cable is properly identified.  
Each Ethernet cable in use meets quality requirement CAT5E STP (Shielded Twisted Pair) or better.  
The transducer cables can move freely when the transducer is lowered and hoisted.
