1 Introduction
This manual provides the information needed to use the Pandora Enclosure with Diamond Systems PC/104 CPU
cards, including Athena, Elektra and Prometheus.
The manual includes,
●An introduction to the product.
●Detailed product physical dimensions
●Installation information
●Connector and other Configuration Information
Description and Features
Pandora provides an easy to assemble, lightweight, rugged and flexible enclosure for PC/104 systems. There are
two versions of the Pandora enclosure.
●The generic version provides a flexible enclosure for arbitrary PC/104 stacks. With the generic version of
Pandora, I/O connectors and system cabling is the responsibility of the user.
●The second version of the Pandora enclosure is customized to Diamond Systems PC/104 CPU products. When
the system CPU is a Diamond Systems PC/104 CPU, Pandora provides additional functionality that eliminates
the need for much internal cabling and provides a set of standard I/O connectors to the outside world.
This standardized interconnect scheme speeds up the assembly process and improves reliability and ruggedness. A
panel I/O board plugs directly onto the Diamond Systems CPU card and converts all CPU I/O signals to industry
standard connectors. The panel board then mounts directly to the matching front panel of the enclosure. The entire
PC/104 stack is held firmly in place with direct connections to both the top and bottom of the enclosure for extra
rigidity. The rear panel provides convenient corner holes for quick mounting of the complete system.
The new Pandora Panel I/O Board is compatible with Diamond Systems Elektra, Athena, and Prometheus CPU
boards. All three CPUs contain the same set of I/O connectors, with the same features in the same locations. The
Pandora Panel Board has connectors for basic computer functions, including keyboard, mouse, VGA, Ethernet and
USB. With the Pandora enclosure, you can build a rugged, cable free PC based controller using the CPU of your
choice.
The Pandora Panel I/O Board design also accommodates up to two add on PC/104 modules without requiring costly
and time consuming enclosure redesign. A supplementary 50 pin connector can be used with any PC/104 board
with a 50 pin I/O connector to provide additional analog or digital I/O to the outside world. Two additional 20 pin
connectors can be used with any model of Diamond Systems Emerald MM Serial PC/104 Module to support 4
additional serial ports (for a total of 8). With all I/O, whether from the Diamond Systems CPU or additional PC/104
boards, the Pandora Panel Board provides real world PC style I/O connectors.
Pandora is available in multiple case lengths. The 1.7" size accommodates one CPU and the panel I/O board. A
3.0" case enables the addition of up to two add on PC/104 boards. Other standard sizes include 5" and 7". Custom
lengths and finishes are also available.
