TRANSDUCER CONNECTION FOR NO. 530 and 550
DEPTHFINDERS:
The transducer connectors on the No. 530 and No. 550
Aqua Probe digital depthfinders are special HEAVY
GOLDPLATED, MIL-SPEC VERSIONS of the industry-
standard universal RCA type phono connectors. These
connectors are provided both on the transducer cable
and the unit itself. The connection is simply made by
inserting the plug on the cable into the socket on the
back of the depthfinder. Use a slight, clockwise twisting
motion, until the connectors are seated properly.
Disconnection is accomplished with a similar clockwise,
twist/pull action.
WARNING: NEVER ATTEMPT TO REMOVE THE
PLUG BY PULLING ON THE CABLE! Always use the
knurled hold-area of the connector as a grip in
disconnecting the transducer.
Additional transducer-installation information is provided
with the transducer. Each of the transducer types-
transom mount, thru hull, or puck-type-has its own
installation requirements.
TRANSDUCER CONNECTION FOR THE NO. 540
REMOTE
The No. 540 digital remote indicator is completely self-
contained. No modification to your existing depthfinder
head is necessary. All you have to do is plug the
transducer cable into the No 540 remote, plug the No.
540 remote's jumper cable into the transducer socket on
your depthfinder, and provide a 12V-DC, negative
ground power connection. The accuracy and sensitivity
of your depthfinder will not be affected. The No. 540
remote depth indicator connects directly to any Aqua
Meter or other popular depthfinder in the 175 to 225 KHz
range.
The only connection between your new Aqua Probe No.
540 digital remote depth indicator and its master "main"
depthfinder is the Jumper Cable which is supplied with
the unit.
If the main unit is a flasher or graph depthfinder, you
may want to install your new No. 540 digital nearby.
Assuming the main depthfinder's transducer connector is
a standard, RCA phono type of plug, simply plug the
main
depthfinder's
transducer
directly
into
the
appropriate, transducer
