Currently I have 2 helix 12’s on the now. One is a msi+gps g4 n Cho. I have my mega si+ di + duel spectrum transducer connected to it. My other unit is helix12 mdi +gps g4n Cho with my mega 360 connected to it. I ran my active lock live to a 5 port box with both units also connected to the box. Is all this going to work I haven’t tried it on the water yet only in the garage.
You will probably have cross-talk issues with that installation unless you turn off the unit with the SI transducer connected or don't use the MEGA Imaging frequency.
For a trouble free operation, you connect the MSI+ transducer and MEGA 360 to the same unit via M 360 Y cable. When you do that 2D, DI, and the two SI piezos (M360) are pinged in a sequence so they cannot cross-talk.
The MEGA 360 is a rotating Side Imaging transducer so it does either Side Imaging or 360, but not at the same time.
It replaces SI on a SI+ model and adds SI to a DI+ model.
If you have MEGA LIVE/Target Lock, it will be affected by the non-sequenced Imaging of the two units. A proper installation lets the MEGA LIVE's Interference Rejection setting deal with cross-talk since it can change its ping sequence to fit in with the others.

Thank you for the response I just ordered the the Y cable. Does it matter witch unit I hook ea up to seeing one is a msi and the other is mdi.
No, it makes no difference.Originally Posted by lobsterman0476
