ADC1000-USB Overview
USB Port
The ADC1000-USB interfaces an S2000 Spectrometer to a notebook or desktop PC via a USB
port. When interfaced to a PC via the USB port, the ADC1000-USB does not require an external
power supply -- it draws its power from the PC to which it is connected.
The ADC1000-USB can connect via the USB port to any PC that uses a Windows
98/Me/2000/XP operating system and has OOIBase32 installed and configured for use with your
ADC1000-USB. If multiple PCs meet these two qualifications, you can switch your ADC1000-USB
and spectrometer among them.
The ADC1000-USB connects to the back of an S2000 Spectrometer and
interfaces to a notebook computer via the USB port and USB cable.
Serial Port
ADC1000-USB Operating Instructions 2
The ADC1000-USB also has a serial port for interfacing the S2000 or S1024DW Spectrometer to
PCs, PLCs and other devices that support the RS-232 communication protocol.

7. Enter a value from 1-500 in the Pixel Resolution text box.
This value specifies that every nth pixel of the spectrometer will transmit from the
ADC1000-USB to the PC. Sacrificing resolution equates to an increase in speed. The
transfer of one complete spectra requires approximately 0.3 seconds at 115,200 baud. If
you need information more frequently than 0.3 seconds per spectra, increase the
resolution or enable data compression (see Step 8).
8. Select the Compress Data check box to enable the Compress Data function.
This option minimizes the amount of data transferred over the RS-232 connection. As
transmission of spectral data over the serial port is a relatively slow process, enabling
