For the old driver, we have - see linked entry:
"3. DACs of new RTP cell:
IGL0I00C1068_DAC05, IGL0I00C1068_DAC06, IGL0I00C1068_DAC07, IGL0I00C1068_DAC08, IGL0I00C1068_DAC09, IGL0I00C1068_DAC10, IGL0I00C1068_DAC11, IGL0I00C1068_DAC12."

We should keep these for the time being in case we need to go back to the old driver.

For the new drivers, we should add these PVs to the Hall A Gateway Channel Access:
