2.4.5
Installing the Processor to Sonar Head Cable
There are two general installation scenarios, shipboard and ROV/UUV. The fol-
lowing is a brief discussion of each installation.
2.4.5.1 Shipboard
Installation
The standard shipboard cable is 25 meters in length. Prior to securing the cable
in place, verify that there is sufficient slack at the wet-end to allow an easy on/off
connection process. There should be no tight bends or strain on the connector
section when fully mated (see paragraph 2.4.5.2). If applicable, do not put the
last cable clamp in place until the connector is attached and secure. Place small
plastic bags, or other protective wrapping, over the exposed cable ends during
the process of putting the cable in place.
CAUTION
Verify that mains power is OFF prior to making, or breaking, any system cable
connection.
The cable connection at the sonar head is a 9-pin waterproof pressure immune
connector. Before connecting, ensure that both male and female connector sec-
tions are clean and dry. Use alcohol or fresh water and a lint-free cotton swab to
remove any dust or residue. A very light film of 3M Silicone Spray (or equivalent)
on the mating surfaces will allow a smooth connection. When the connector set is
fully mated, RESON recommends the use of tie-wraps to lock the two halves to-
gether of prevent inadvertent separation.
The dry-end of the cable should have enough slack to allow the sonar processor
to be withdrawn from its rack-mounted position. This end of the cable has a pre-
wired MS-type connector and a back shell that provides the required strain relief.
Prior to connecting, ensure that both the male and female halves of the connec-
tor set are clean and dry. Use a small brush to remove any accumulated dust
and debris.
