Title: Helix 12 mega and 998 HD Si
Post by: hgv on October 05, 2017, 07:28:29 AM
any known issues with the Mega 12 and 998 when it comes to networking then together? Can I use the new mega transducer with the 998?

998 will be able to share waypoints, accessories, 83/200kHz 2d Sonar, and 455/800kHz SI from the MEGA units  ...

998 cannot share MEGA 1200kHz, CHIRP 2d , CHIRP imaging, nor the dedicated DI from the MEGA unit  ...

So does that mean that the 998's imaging will work through the mega transducer but just at the 998s freq?

Correct  ....Turn CHIRP imaging off in the MEGA and 455kHz and 800kHz imaging should share from the MEGA xducer to the 998  ...

Side note  ...: There will be a DI image in the 998 when subscribed to the MEGA xducer (with CHIRP imaging turned off in the MEGA unit)  ...

But the DI image in the 998 will not be from the dedicated DI piezo in the MEGA xducer  ... The DI image in the 998 will still be a blended computer generated image from the SI piezoes (in the MEGA xducer) processed into a format that looks like a DI image  ...

The 998 has no dedicated DI technology processor capability regardless of what xducer it is connected to or subscribed to (thru Ethernet) ...
