AD9102: How set RUN bit in PAT_STATUS register?

Sorry for the NOOB question but I am picking up work during someone else's vacation.

I am running the ad9102 through the Quick Start LabVIEW ad9102.vi and all is going well.

I want to set the board so it can be triggered remotely.

I believe I have to set the RUN bit in the pat_status register (0x1E) in order to do this.

I can set the PATTERN_RPT bit in the pat_type register (0x1F) either through the GUI or by editing the regval file.

I can't do likewise with the RUN bit either through the GUI or by editing the regval file.

So my question is threefold:

1. How do I set the RUN bit?
2. Do I need to set it to enable remote triggering.
3. Is there any documentation which may shed more light on this?

Thanks in advance,

Simon.
