Installing Digital Sprite - Dedicated Micros Digital Sprite 2 Setup Manual

Installing
Before you start:
Check the contents of the box:
Digital Sprite 2
IR remote handset
PSU
Mains cable with three pin plug fitted (North America)
Mains cable without plug fitted (other regions)
Rack mount kit (rack mount ears, rear supports, and fixing screws)
485-bus cable
Choosing a location for installation
Digital Sprite 2 is designed to be rack or desk mounted. The following precautions
must be taken when installing Digital Sprite 2:
• Openings in the unit's case are provided for ventilation. To prevent
overheating, these openings should not be blocked or covered.
• When stacking units, ensure there is at least a
each unit.
• Ensure there is a 1" (3cm) gap on either side of the unit.
• Ensure the unit is not located in an area where it is likely to be subjected to
mechanical shocks.
• The unit should be located in an area with low humidity and a minimum of
dust. Avoid places like damp basements or dusty hallways.
• If using external storage, refer to the manufacturer's instructions for
placement details.

A quick overview of digital recording
Digital multiplex recorders work in exactly the same way as analogue multiplexers
except that they use hard disks and digital tape to store video, instead of VCR tapes.
Analogue recording uses time-lapse recording to extend the length of time
recorded onto a 3-hour tape - recording fewer pictures every second.
Adjusting the number of pictures recorded every second also extends the length
of time recorded onto the hard disk of a Digital Sprite 2. However, other factors
also determine the amount of time that can be stored on the disk of a digital
multiplex recorder:
• The image quality
• The record rate
• The hard disk capacity
Image quality
Digital multiplex recorders store images in a compressed format, allowing images
to be recorded more efficiently. The higher the compression, the smaller the file
size, but the image quality will suffer. Digital Sprite 2 can compress images
between 6KB and 45KB.
Kilobytes and gigabytes are units of storage:
1GB = 1024 Megabytes (MB)
1MB = 1024 Kilobytes (KB)
With analogue recording, the image quality is dependent on the type of VCR
being used; VHS or S-VHS. Digital Sprite 2 allows the image quality to be altered
by adjusting the image size, for example, VHS quality is 14KB, S-VHS is 18KB, and
greater than S-VHS is 25KB*.
Using a larger image size will fill the hard disk faster than a smaller image size, as
more space is required to store it. To achieve the same amount of recording time
when a larger image size is used requires the record rate (PPS) to be reduced.
* Note that as for all digital recording, image quality can vary for different scene types, S-VHS
quality may be 18KB in one scene, but it may be 30KB or more to get the same quality in a
scene with more detail.
