[CA] Upgrade e127 to Axiom Pro - considerations

[john744]

I am considering upgrading my existing e127 and e125 to Axiom Pro 12" MFd's. I have a couple of specific questions that I could use help with. I am basically trying to upgrade my sonar capabilities with RealVision, but keeping as much of my old system as possible.

Currently
e127 (Master) connected to HS5 Switch and to SeaTalk NG bus
e125 (slave) connected to HS5 Switch and to SeaTalk NG bus
HS5 Network Switch connected to e127, e125, RD2420, CP100, CP200
Bus SeaTalk NG connected to e127, e125, RS130, Yamaha Gateway
Radar RD2420 connected to HS5 Switch
CP100 DownVision connected to HS5 Switch
CP200 SideVision connected to HS5 Switch
Depth Transducer A80171 (P319) connected to e127
L3 Protec-M AIS connected to e125 NMEA 0183
KVH AutoComp 1000 connected to e127 NMEA 0183
iCom VHF connected to e127 NMEA 0183
GPS Receiver RS130 connected to SeaTalk NG Bus
Yamaha Gateway connected to SeaTalk NG Bus
FLIR M625L (analog) connected to video input e127 and e125
Deck Camera(analog) connected to video input e127 and e125



Am I correct by specifying an AXIOM PRO 12 RVX to replace the e127 and an AXIOM PRO 12 S to replace the e125? Using the RVX as the "master" and utilizing the RealVision from this MFD I hope to share RealVision data display to the S (slave) through a HS5 network switch.

Transducer selection: My current system is using a Raymarine A80171 (Airmar P319) for depth sounder and transom mount transducers on the CP100 and CP200. These transom xducers are problematic I want to use a through hull (aluminum hull). Is it better to use the single xducer or use a split pair (T70319) and keep the existing depth sounder? The P319 is in a flat area (0 degrees) along the centerline 12" wide. The adjacent hull area has a deadrise of 25 degrees. Will the split pair interfere with the P319 or vice versa? Does the split pair offer better resolution?

NMEA 0183 remains the same on the Axiom Pro and my Protec-M AIS, AutoComp 1000 and iCom VHF should be a straightforward connection. Correct?

SeaTalk NG remains the same on the Axiom Pro and my GPS receiver and Yamaha Engine Gateway should be a straightforward connection. Correct?

Video: Axiom Pro only has 1 analog video input but will support up to 10 ip cameras. I'll have to figure this out as I can maintain the FLIR but will have to modify the rear deck camera using a video switch or something.

Any advise or recommendations are greatly appreciated. Also, if there's something I've overlooked, please bring it to my attention. Thanks!
