Helix 12 DI

Do they make a High Speed Transducer for the Helix 12DI unit. I don't think the XNT-20-T 20/60 is compatible. Also can you use a AS-SIDB-Y cable with a DI unit or do you have to use a transducer switch.

The HELIX 12 DI has a "Connected Transducer" selection for "DI + 200/83" ...

This means the HELIX can transmit the the correct frequency for the shoot thru XP 9 20 ...

There seems to be some conflicting information about the use of the AS SIDB Y cable with the HB DI units ...

So I went to the source that everyone concurs with ...

Here is my correspondence with Deb at HB (Deb is in blue) ...

Hey Deb ... There have been some discussions on the forums about the possibility of using the AS SIDB Y cable with a HB DI unit along with a secondary Dual Beam xducer of the appropriate 2d dual frequency ...

Some have posted actually talking with HB representatives that claim the AS SIDB Y cable will only work with the HB SI units ... and could even damage the DI unit from extending use with the AS SIDB Y cable ...

It is obvious from the HB pinout diagrams that the #1 pin channel for the XHS 9 HDSI 180 T (and XTM 9 SI 180 T) "Right SI channel" is the very same #1 pin channel for the XNT 9 DI T (and XTM 9 WIDE DI 20 T ) "DI channel" ...

Therefore the #1 pin channel thru the AS SIDB Y cable should (in theory) effectively transfer data from the HB DI unit "DI transmitter" to the HB DI unit "DI piezo" ... (It is just a wire with no impedance filter, I assume) ...

Can you shed light on why using the AS SIDB Y cable with a HB DI unit and a secondary Dual Beam xducer (of the appropriate 2d frequencies) is not recommended by some HB representatives ...??

Thanks Rickie

You can use the DI transducer and a dual beam transducer (not a US2 transducer) with the AS SIDB Y without any issues as long as you have the DI transducer on the SI transducer side.
