[CA] [CA11] Replace ST8001 with p70RS control head

[hynespa]

I see in the autopilot FAQ the thread "Can the p70/p70R/p70S/p70RS Autopilot Control Heads be used with older autopilots?" that the p70RS can be used with the S3G autopilot computer.

I have two follow-up questions:

1) I would be looking to replace the ST8001 control head with a p70R control head. Where can I found the cutout dimensions for the ST8001 vs the p70RS so I know if the newer p70RS control head will fit in the [censored] that was previously cut in the dash panel for the ST8001? If it turns out the p70RS is smaller - is there any adapter piece available so that there is not a [censored] in my dash?

2) I have attached a network diagram of my current setup. As you can see I already have a D244 SeaTalk Junction. It looks like in the FAQ referenced above this junction would make the connection between the S3G computer and p70RS controller. Could I use the existing D244 junction, or would I have to add a second D244 junction? On the D229 cable that currently connects the S3G to the p70RS would I leave the red cable connected to the autopilot computer?

Thank you your help is always appreciated!

Welcome to the Raymarine Forum hynespa,

Q1) I would be looking to replace the ST8001 control head with a p70R control head. Where can I found the cutout dimensions for the ST8001 vs the p70RS so I know if the newer p70RS control head will fit in the [censored] that was previously cut in the dash panel for the ST8001? If it turns out the p70RS is smaller - is there any adapter piece available so that there is not a [censored] in my dash?
A1# The circular [censored] on required to surface mount the ST8001 is identical to that required for a p70S/p70RS/p70/p70R Autopilot Control Head.

Q2) I have attached a network diagram of my current setup. As you can see I already have a D244 SeaTalk Junction. It looks like in the FAQ referenced above this junction would make the connection between the S3G computer and p70RS controller. Could I use the existing D244 junction, or would I have to add a second D244 junction? On the D229 cable that currently connects the S3G to the p70RS would I leave the red cable connected to the autopilot computer?
A2) Within your diagram, each of the D244's SeaTalk sockets are presently in use if replacing the ST8001, it would simply be recommended, that the SeaTalk cable which is presently connected to ST8001 be unplugged from the ST8001 and instead be interfaced to the new D244. An A06047 400mm SeaTalkng to SeaTalk Adapter Cable would then be used to connect the p70RS to the new D244.
