The AS SIDB Y cable disconnects the 2d channel wire going to the 2d piezo in the XHS 9 HDSI 180 T ...
And re-routes the sonar signal to the "Dual Beam" xducer ...
With the AS SIDB Y cable ...:
*SI/DI and temp will always come from the XHS 9 HDSI 180 T ...
*2d will always come from the Dual Beam xducer ...
The settings in the unit do not change as this is merely re-routing wires ...so the unit will still see this setup as 1 xducer ...
