INTRODUCTION

The QImaging EXi Aqua Bio-Imaging Microscopy Camera has been engineered for, high-speed, high-sensitivity
applications. A Peltier device provides cooling to 0 C. The EXi Aqua camera features a 1.4-megapixel CCD, 14-bit
digital output, and an IEEE 1394B interface for enhanced connectivity and noise-shielding performance.

Power requirements

The EXi Aqua camera can be powered through a single IEEE 1394B FireWire 9-pin to 9-pin cable when the
cooling is off. When the cooling is on, the camera must be connected to the included external power supply.
• • • • Power supply requirements
13.5 watts, 12 volts dc

Host requirements

For Windows PCs:
• Pentium 4 CPU, running at a minimum of 1.6 GHz.
• 512 MB RAM (1 GB RAM preferred).
• Video card with 8 MB video memory capable of 32-bit color output.
• Windows XP Professional (with Service Pack 3 installed), or Windows Vista Business or Ultimate
edition (with Service Pack 1 installed) operating system.
• If the PC is not equipped with a FireWire 800 / FireWire B card, the included card must be
installed.
IEEE 1394B (FireWire) interface
The EXi Aqua camera can be powered and controlled through an IEEE 1394B (FireWire) digital interface.
A single FireWire connection from the camera to the computer combined with the external power connection
will allow full control of the camera and rapid image data transfer from the camera to the computer.

Cables

A ten-foot FireWire interface cable is included with the camera. One end of this cable connects to either of the
available FireWire ports at the back of the camera. The other end of the cable plugs into your computer's
FireWire port.
Some computers have 4-pin FireWire ports. These ports may be used if they are OHCI compliant, but you will
need to purchase a 4-pin to 9-pin FireWire cable from your local computer store or from QImaging. When
connecting the camera to any FireWire port, you will need to use an external power supply.
Note: 4-pin FireWire ports are FireWire A (400 Mbps) ports. Some settings will not work unless the
camera is connected to a FireWire B port.
