Ocean Optics QE Pro Install - Manual (Page 8)

1: Introduction
2 891-00000-000-02-201401
The QE Pro’s onboard module has 10 user-programmable digital I/O lines for interfacing to other
equipment; and a pulse generator for triggering other devices. You can use the I/Os to flash a lamp,
stop/start a process, and send a message/alarm during the spectrometer’s integration period. The
spectrometer’s operating parameters can be controlled through software. In fact, wavelength calibration
coefficients unique to each spectrometer are programmed into a memory chip right on the spectrometer.
The QE Pro’s high-speed electronics have been designed for considerable flexibility in connecting to
various modules and external interfaces, including PCs, PLCs and other embedded controllers, through
USB 2.0 or RS-232 communications.
A +5 VDC external power supply is required to operate the spectrometer. This power supply is included
with your spectrometer.
Models
The QE Pro is custom configurable for your specific application. In addition, the following preconfigured
models are offered:
