Gordon, Oct 4

Went to rim tower to deliver some CSAT3 cables to Matt who climbed up from the ssw4 sonic.

While at rim, I screwed in the serial connector on the bottom of the Paro6000 barometer, P.2m.rim. It was not fully screwed in.

After returning to the base I noticed that all data from rim had stopped.

Returned to the site. Console was reporting many messages, something like the following:

"Too much work for IRQ 4"

IRQ4 is the second Emerald serial card.

Disconnected all sensor connectors at the interface panel to the emerald ports (5-20). Error messages didn't stop. Removed the ribbon connectors on the inside of the interface panel. No effect.

Could not get a shell prompt at the console. Power cycled at 4:28. System came up. Reconnected all serial cables. All are working, even the 15 meter CSAT on port 7 and the barometer on port 13.

Will have to watch this system. Perhaps it was due to a loose connection of the barometer on port 13, or a questionable serial card or something amiss on the Titan.
