5.1 Remarks on Cabling
1. Cable between transducer and transceiver unit
This cable carrries very weak signals having amplitude
of less than 0.1 µV, which are easily interfered by noise.
Therefore, dedicate steel conduit tubing exclusively for
this cable. For the conduit which runs vertically, line it
with vibration absorbing material prevent cable vibration.

2. Cables between transceiver unit and processor unit
(via junction box DS-360)
These cable carries echoes signal having amplitude of
greater than 0.1 mV, which can be interfered by noise
from high power electrical power cables. Therefore, do
not run these cables through steel conduit tubing with the
following cables:
•
Cable carrying more than a few kilowatts of
power to fluctuating loads.
•
Cable carrying switching waves generated
by thyristor, etc.
•
Transmission antenna cable of radio
equipment.
Observe also the guidelines given for "3. Other cables."
