Introduction
The GEMINI 1U ICE system serves as a high performance, compact 19" rack mount ruggedised PC
system for applications in IT systems, machine control, and kiosk solutions. The GEMINI 1U ICE is
powered by an Intel Core 2 Duo / Core Duo / Core Solo / Celeron M processor based single board
computer designed and manufactured by Eurotech. The motherboard and system components are
designed for long life support with scalable CPU options from the Celeron M 440 1.86GHz for a wide
operating temperature, up to powerful server grade systems fitted with the Core 2 Duo T7400 2.16GHz
CPU.
This ruggedised system has a full compliment of PC features including quad Ethernet (with Gigabit
capability), USB ports, serial ports, multiple video outputs and a number of additional features for
creating secure systems. The system can also be fitted with 2 PCI add-on cards.
The front panel LCD display and navigation buttons can be used for user-defined configuration and
control for deeply ‘embedded systems’ which do not have access to a display. Please refer to the
GEMINI user manual for detailed information about the performance and operation of the GEMINI
SBC.

Fan control
There are two fans in the GEMINI 1U ICE constantly spinning at maximum speed, the CPU fan, and
the system fan.
The AC PSU’s fan is thermally controlled. It therefore runs at a speed proportional to the power
consumption.
There is also a controllable system fan supplied in the GEMINI 1U ICE which helps to cool down the
PCI cards and to extract warm air out of the box. It might be required to turn it on when one or two
high-power PCI cards dissipating some additional heat are fitted. This extra fan is controlled by the FPI
board and its command is automated so the system decides whether the fan needs to speed up or
slow down.
Control of the system fan is implemented using drivers supplied by Eurotech. These functions are fully
programmable and are available as user-defined controls for OEM customers. Drivers are available for
Windows XP and Linux.
Contact Eurotech Technical Support for further information (see page Eurotech Worldwide Presence).

LINE_IN, MIC, LINE_OUT – Audio connectors
3.5mm stereo audio jacks are used for audio connection. The audio codec can operate in either of the
following modes:
2.0 mode, which allows for microphone in, line in and line out operation.
5.1 mode, which provides six-channel surround sound output. The microphone input and line
in are not available during six channel mode.
Selection of 2.0 or 5.1 mode is made under software control.
The audio connectors are illustrated in the following diagram:

The maximum voltage range allowed by the DC input is 8 to 24VDC. The power rating of the DC input
source must be chosen in accordance to the maximum power consumption of the GEMINI 1U ICE.
Worst case: 100 Watts (figure taken with T7400 processor stressed to the absolute maximum power
and with two additional PCI cards in operation)
The DC input does not have any polarisation protection.
1The CHASSIS pin can be either left unconnected or connected to the network earth, but it must not be shorted
with GND (pin3) in order not to override the EMC filter.
