The analog outputs are controlled by the wavelength, bandwidth, rise time, and zero
functions of the detector. These outputs are made 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
The Surveyor PDA Plus Detector arrives with the unit ID preset using the two rotary switches
located on the back panel (see
value of 00 is reserved for special service functions. The unit ID must correspond with the
stack ID specified in the Instrument Configuration application. Do not change the unit ID
setting for your detector unless you are controlling more than one PDA detector from one
computer. For details on configuring your detector, see
Use a small flathead screwdriver to change the setting of the rotary switches.

The Surveyor PDA Plus Detector has the remote communications inputs RUN and ZERO,
and the remote communications output EVENT.
The RUN input receives an inject signal from the autosampler. The system interconnect cable
connects the RUN input to the signal from the autosampler.
Use the ZERO connection on the back panel of the detector to zero the detector signal output
from a remote device (generally at the start or end of each sample run).
The Surveyor PDA Plus Detector can be zeroed remotely with either a TTL low signal or with
a contact closure.
The system interconnect cable connects the ZERO input to the signal from the autosampler.
