I bought a new HDS 12 Live and Active Target (Gen 1) last night and will be installing it tonight, probably all weekend . The live 12 will be going at the bow and connected via ether net and NMEA 2000 to one HDS Gen 3 and One HDS Gen 2 unit at the console. Also on the NMEA network is a Point 1, an external temp sensor, and SmartCraft. I have existing dedicated power for the bow unit that runs directly to the battery. My trolling motor is an Ultrex with the internal sonar. The active target box will be mounted in the center rod locker on my Ranger. I have a few questions.
1. Reading another post I don't think the Gen 2 unit will work on the network with the Live unit. Is this correct? If so, can the gen 2 unit be disconnected from the ethernet network and remain attached to the NMEA 2k network to access the Point 1?
2. How high up the shaft of the trolling motor should I mount the AT Transducer to avoid interference from the motor?
3. Can I use the transducer built into the trolling motor for regular sonar and turn it off when using the AT?
4. I have an accessory switch available on my bow panel. Would you recommend using this for the wake up wire on the AT box?
5. When I use Active Target do all other sonar sources on the boat (Side Imaging, regular sonar at the console) need to be stopped?
6. My current laptop does not have an SD card slot so getting a software update on the card will be a challenge. I see the new Live unit has a USB port. Can I upload the software update to a USB drive and update the software that way.
Thanks in advance for the help. I am sure I will have many more questions once I get into this.
