Missing ELSD Signal in Chemstation

Discussions about HPLC, CE, TLC, SFC, and other "liquid phase" separation techniques.

I am using Chemstation B.01.03 (Rev. B) and I hooked up Sedex 75 through Agilent 35900E. I see the plot/signal in online signal but don't have it in my report. When method was set up, ADC Signal window states collect "all data", my Agilent 1100 starts 35900 and I added ADC1 (Channel A) to the Signal Details.
What I am missing?

This issue seems consistent with not having a remote 9-pin cable plugged into the 35900 and also into the Agilent stack. In other words: we had that issue and learned that a few decades ago.
Thank you. Do you know part number for this cable from Agilent?
I am puzzled why this cable is needed. My Agilent receives the data from ELSD and plots it in Signal Window, but not in the report

CPG, this worked. Thank you for your advice.

Great !!! Like I said: we learned this long ago. Signal was visible in "plot" window but no vertical red line appeared at start of injection, need the remote cable.

I believe it's sending the trigger to start/stop acquisition for the chromatogram. Basically triggering the software to write the signal to disk. It will display the analog signal, but that's not stored unless triggered to do so by the ADC box. Odd way to do things, but that's always been my guess.

CPG will probably know for sure.
