Ocean Optics QE65 Pro - Manual (Page 8)

1: Introduction
2 220-12200-000-02-201303
The QE65 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.
TheQE65 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. Its USB 2.0 interface enables full spectral scans into memory every
7 milliseconds.
The QE65 Pro operates via USB interface. A +5 VDC external power supply is required for the TE
Cooler (TEC) and to operate the spectrometer via an RS-232 interface. This power supply is included
with your spectrometer.
