WP4834 Jim and Dave
We replaced the 16bit DAC card in h1oaf0 (PCIX card on PCIe adapter) with a PCIe DAC card. This is the second DAC card in h1oaf0, the first is an 18bit DAC. Procedure was:
This does not close out the WP, we have SUS EY and SEI EX still to complete.

Alastair later found that the new DAC card was not functioning correctly. We found that channel 12 was outputting 24V instead of 8.4V. We tried swapping out ribbon cable and interface cards, but eventually put the original DAC-on-carrier-card back in to get TCS back on track for this evening. We will investigate further later in the week.
