Pre-Flight, still having problems booting DSM 305. However, with the help of Catherine, we were able to get it running and it functioned properly throughout the entire flight.
When chatting with Josh Carnes during the Research Flight he suggested changing out the Serial Card as this was the only card left from the original configuration.
Swapped out the Serial card post-flight.
The change of the Serial card had no positive effect on DSM 305.
To see if the DSM would function with the Console port hooked up (like pre-flight), we decided to use the Surface tablet. But instead of trying to watch it boot on the tablet, John and I decided to first connect the Serial-to-USB Adapter to the Console port. (Nothing connected to the Surface tablet yet) DSM 305 booted just fine. We decided to test this a few more times with and without the Serial-to-USB Adapter connected. Each time the Serial-to-USB Adapter was connected to the Console port, we had a successful boot. This explains why we are always able to boot the DSM when we have the Surface tablet hooked up in either the cabin or at the Nose-because it is connected via the Serial-to-USB Adapter.
The previous CPU card, while bad, did not exhibit these symptoms. At this time we are still not sure if we are dealing with a bad card or a faulty connector. But we are quite certain we have isolated the problem to the CPU.
Moving forward - We will fly RF11 with a Serial-to-USB Adapter connected to the Console port behind the ADS rack. Our next Maintenance Day is scheduled for Thursday, 9/5. John and I will determine a fix for the Nose DSM then.
