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:

RTPXPORT1Q1calc.A
RTPXPORT1Q4calc.A
RTPXPORT2Q1calc.A
RTPXPORT2Q4calc.A

RTPXPORT1Q2calc.A
RTPXPORT1Q3calc.A
RTPXPORT2Q2calc.A
RTPXPORT2Q3calc.A

The display should show the status of the new two RTP HV Drivers ALARM bits, RTP1 ALARM and RTP2 ALARM: RTPXPORT1DRDBK, RTPXPORT2DRDBK.

Under "Screens", Hardware Controls: RTP Cell show open the "Injector->Parity->New RTP Driver" screen.

For the new RTP HV Drivers, we want to add these signals to the alarms. We want to keep in the alarms the old RTP Driver but have it disabled, in case we have to go back to the old one.

Under LASER-INJECTOR-POCKELS CELL, we should add both "RTP 1 HV DRIVER" and "RTP 2 HV DRIVER". The two signals are "RTPXPORT1DCTRL" and "RTPXPORT2DCTRL", "1" ON, "0" OFF.

We want also to add to the Alarm the eight HVs.
