New Install Simrad AP42- guidance needed

[Offline30]

Hello,
This gear while old has never been installed and spent it's life as spares in a dry locker.

New to me Simrad autopilot components.
AP24 Autopilot
AC42 Autopilot Computer
RPU160 Hydraulic Pump
FC40 Fluxgate Compass
RF300 Rudder Feedback

-The install is following this diagram that comes directly from the Simrad Manual

- The Simnet power supply does have a RED connector. There is another termination plug that at the moment I have jacked into the second port of the AP24. This power is from another source that the 12v that feeds the AC42 computer.


- This is the Rev that is loaded on the device
-
- On powering up the system I am not getting any data moving across the network , the display looks like this.
- I cannot “see” other devices
- I cannot perform commissioning actions

-
-

Going into the service menu, this is what the network tab looks like


Actions so far;
- Obviously, there is some connectivity on the network as the AP42 will power up and allow me to scroll through menus.
- I have changed out the 7 port multi-joiner with no change in results.
- I have inserted the AP42 into another boat’s network ( that has the same set up) and it joined the network and was fully functional on power up- this tells me that the unit itself it good (? )
- I have changed the data cable between the AP42 and the multi-joiner with no change.
- I have done both types of resets offered in the service tab.
- The RPU160 is functional in that I tested by adding current directly to it.
- The AC42 computer is showing a green LED that indicates polarity is correct to the drive.
- Voltage to AP24 is within parameters.
- All cables are visually intact and have not been cut or spliced.
- All cables are stock lengths and do not exceed length restrictions.
- I have tried to jack in to the AP24 various components of the system including direct to the AC42 computer with no change in behavior.
- I have triple verified and rewired twice the Sinmet data cable that runs to the AC42 computer is indicated in the manual.

So any thoughts or guidance are most welcome
Thanks in advance

Did you wire in the 12v supply to the Simnet?

Yes- there is dedicated 12v to the Sinmet network that is separate from the power to the AC42 course computer
