Hi everyone,

we've been trying to connect our Hitachi Chromaster HPLC System to a CAD (Thermo Fisher Veo 'alone-standing' detector) via eSATIN to Empower. Until now we managed to receive some sort of signal while activating the Monitoring mode in Empower. Nevertheless the moment we try to make an injection - the system perform it physically, washes the needle but apparently the eSATIN (or the Pump?) doesn't receive the signal to show it on the display. The Empower shows the the injection running, but the signal window is empty. The Pump also doesn't seem to respond to the action (the run time won't be shown on the mini-pump-display).

We think we might have had the wiring problem. Any ideas, thoughts, experience with the Hitachi-CAD-eSATIN would be highly appreciated!

Thank you and best wishes,
Marina

Hi

Sounds like the Inj-start is not triggered to all systems. Check and find out how to do that.
Normaly the each device prepares the injection and then waits for one to give the inj-start.
if I rembember well, this signal should also be wired to the the eSatin.

Yep - eSAT/IN requires external trigger, usually a pair of wires running from autosampler to terminal block on eSAT/IN.

Got that?
