Upgrade RS120

[shay]

I have a L760+ and ST6001+ connected to one of the Seatalk ports on my 400G Course Computer. The other Seatalk port has a RL80c+, ST6002, RS120 and RF base for wireless remote. My RS120 has started loosing fix and taking a long time to regain fix, doing a restart will sometimes help but not reliably.

I am looking at replacing my RS120. I have a friend who replaced his RS120 with a RS130, but when I went to order the RS130 and ST to STng converter I found the RS130 is available but no longer made. I see the RS150 has replaced the RS130.

Will the RS150 work with my vintage electronics without any loss of functionally?

My RS120 is mounted on my radar arch 21' from the nearest Seatalk1. I will use the ST1 to STng converter E22158 to connect to ST1 at my upper helm and a 5m A06036 Backbone cable to reach the bottom of the radar arch. The Backbone cable will be connected to a T-piece A06028 which will attach to the 3m spur cable that comes with the RS150 which will attach to the RS150 E70310 on the arch. I would prefer to use a 5m spur cable to run from the converter to the RS150 but can't find anyone who has it in stock.

I haven't used Seatalk ng before so I want to be sure what I am ordering will work.

My two Seatalk branches are powered at the G400 and each branch has a separate 4 amp fused power feed. Will the ST1 to STng adapter pass power through to the RS150 or will I need to use the power cable that comes with the adapter?

Thanks for your help
