Can anyone answer as to whether this OTS set-up will talk to
Helle underwater comms or others?

Connector
I
am trying to digest this thread on Standard Thru- Hull for comms. So it
looks like we have two ways to share the OTS equipment for the
convention.
1)
Standardize on the connectors on the SSB-2010 between the radio
and transducer that Al speced and everyone makes use of any hull bulkhead
connectors and associated cables they have.
2)
Standardize on the connectors on the SSB-2010 between the radio and
transducer and standardize on BH4F / IL4M bulkhead penetrator.
We
can use Daniel's gear either way.
I
am leaning to option 2 for my boat.
I
am in the process of ordering three OTS units:
1
STX-101 (4 channel surface transceiver)
1
SSB-2010 (4 channel Diver transceiver)
1
CDK-6 (Headset with boom microphone, 55 foot transducer cable with connectors)
The
SSB-2010 will be inside the pressure hull as in Daniel's boat.
I
will then take the 55 foot cable (comes with the CDK-6) and cut out and discard
50 foot. This will leave me with two finished ends and two cut
ends. The male finished end (Radio mating connector Al describes) I will
plug into the SSB-2010 unit. The Female finished end with the Transducer
I will secure to my exostructure. I will then take the cut end connected
to the transducer and connect it to the IL4M connector. This connection
will need to be potted with RTV. This modified transducer cable is now
ready to plug into the BH4F bulkhead penetrator. Finally, I will take the
other cut end, whose finished end is plugged into the SSB-2010 radio unit and
connect it with an inline ( TYCO ???) connector to the pigtail coming
off the BH4F bulkhead connector. This will alow me to also share my OTS
equipment with anyone that has the BH4F connector and associated Tyco ???
connector if you want to use my cables as well as Radio and transducer.
1.
Has
anyone speced the inline TYCO male and female connector that would connect
to the BH4F bulkhead penetrator?
2.
What
is the pin out for the BH4F connector and associated pin out on the SSB-2010
unit?

So, is there still any interest in a standard bulkhead
connector? My main rationale for it was to connect OTS cables on any sub, but
it seems like with the cheap Digi-Key source of OTS connectors it isn't needed
anymore as everyone can make a cable set adapted to whatever bulkhead connector
they are using.
It would still be nice to standardize for other reasons, but
no longer necessary.
The OTS cables with "connectors" that I have are
OTS factory made. They are intended to allow the SSB-2010 diver units to be
used as surface units. When I intially purchased the SSB-2010s I used one as a
surface unit and one in my sub. I cut one of the cables , soldered it back
together with water stop pins and then potted it into a thru hull
penetrator that I fabricated. This assembly has worked very well. By
purchasing the connector ends that AL has spec'ed out and using either a
commercially made thru hull penetrator or one you make yourself , It
will be possible to have comms in any sub that wants to dive at the convention
this year . I will post some pictures of the cables , connectors and
comms etc. this weekend.
This really is a functional reliable way to go. I am
very happy with the performance.
Al, thank you for tracking down a supplier for these
connectors. A factory made cable with the two connectors cost $125.00 from OTS.
I will be ordering some spares from DigiKey and saving some money.

RFC - Standard Thru-Hull Electrical Connector
I’m just
referring to the OEM connectors they use. They probably make up their own
cable assemblies in house and do the potting themselves with RTV or epoxy.
Again, I’m
only going by the cables I saw to Dan Lance’s units which are as I described
and used by police, military, etc. I’m sure they all buy their cables
pre-made from OTS.
Regarding
the bell unit, if it’s not a catalog item, I’m not sure how to go about getting
detailed info on it not to mention getting my hands on one to physically look
at it. Besides, I would doubt
they use
the same transducer that they use on their portable 3 watt units. Their
10 watt surface only unit (STX-101) has a transducer where the cable is potted
or molded directly to the transducer
and the
only connector is at the end that plugs into the radio and is the same as the
SSB-2010 units.
Al
OTS sells
what they call a bell unit, which says diving bell to me, and that would need a
full-tilt bulkhead connector. It doesn't seem to be a catalogue item for them,
but I wouldn't be surprised to find they have something to use that doesn't
require a dose of RTV. Police agencies and the military are less than
pre-disposed toward bandaids like that.
