Setting the Analog Output Voltage
You control the analog outputs from the data system by selecting the acquisition wavelengths,
bandwidth, rise time, and zero functions of the detector. These outputs are compatible with
data collection systems using any of the three different voltages (10 mV, 100 mV, or 1 V) by
selecting the appropriate terminal of the analog output terminal connector (see
Figure 41 ).
Making Remote Communications Connections
The UV/Vis detector has the remote communications inputs RUN and ZERO, and the
remote communications output EVENT (see
Figure 42 ).
Figure 42. Remote communications signals
RUN Input Signal
The RUN input receives an inject signal from the autosampler, or from a manual injector, and
sends a run-start signal to the data system software.
During installation, you must connect the RUN input on the UV/Vis detector to your
autosampler or injector output. To make this contact closure connection, do the following:
• If your LC system contains an Accela Autosampler, use the 7-connector interconnect
cable.
• If your LC system contains an Accela Open Autosampler, use the Accela Open
Autosampler interconnect cable and the detector adapter cable.
• If your LC system contains a manual injector or another type of autosampler, connect the
RUN input on the UV/Vis detector to the autosampler’s Inject Out output, and connect
the GND terminal on the UV/Vis detector to the autosampler’s ground terminal.
