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 17 ).
Making Remote Communications Connections
The UV/Vis detector has the remote communications inputs RUN and ZERO, and the
remote communications output EVENT (see
Figure 18 ).
Figure 18. 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 a Surveyor Autosampler Plus, use the 7-connector
interconnect 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.
For other autosamplers or injectors, first determine whether the device uses a TTL signal or a
relay (a contact-closure), to remotely trigger detectors. Refer to the autosampler or injector
documentation to determine whether a TTL signal or relay is used. Then wire the device to
the UV/Vis detector, by doing one of the following:
• If the autosampler or injector uses a TTL signal to trigger the run, connect the TTL
trigger to the RUN terminal on the UV/Vis detector, and connect the signal ground
terminal on the autosampler (or TTL return terminal) to the GND terminal on the
UV/Vis detector.
