You, as the user of the device, should follow these warnings and all other safety precautions
necessary for the safe operation of the device in your operating environment.
Do not operate in an explosive atmosphere
WARNING!
Do not operate the equipment in the presence of flammable gases or fumes. Operation of any
electrical equipment in such an environment constitutes a definite safety hazard.
Antistatic precautions
WARNING!
To avoid ESD (Electro Static Discharge) damage, always use appropriate antistatic precautions
when handing any electronic equipment.
Connection to power supply or other devices
DANGER!
Before applying power to the system, thoroughly review all installation, operation, and safety
instructions.
Failure to install the system power supply correctly or to follow all operating instructions correctly
may create an electrical shock hazard, which can result in personal injury or loss of life, and/or
damage to equipment or other property
•To avoid injuries, always disconnect power and discharge circuits before touching them.
•Only start the device with a power supply that meets the requirements stated on the voltage
label. In case of uncertainties about the required power supply, please contact the Eurotech
Technical Support Team or the electricity authority
•Before connecting other equipment carefully read any supplied instructions
•Always disconnect the power before connecting or disconnecting cables
•Do not perform connections with wet hands
•Check any power cords for damage before use
•Use certified power cables. The power cable must meet the requirements (voltage and
current) of the device.
•Position cables with care. Avoid positioning cables in places where they may be trampled on
or compressed by objects placed on them. Take particular care of the plug, power-point and
outlet of power cable
•Avoid overcharging any power outlets
•Only apply power to the device or connected equipment after checking that all the above
conditions have been met

Installation
WARNING!
•Verify that the mounting location can withstand the added loads caused by the addition of the device, it
should be firmly secured so that it will not cause any potentially hazardous situations (e.g. falling down
due to vibration or shock)
•Do not operate the device near heat sources or flames.
NOTE:
If the device must be moved from one place to another with different ambient temperatures, ensure sufficient
time for the temperature of the device to stabilize before repowering.
Ventilation
WARNING!
Ensure adequate ventilation to avoid overheating, Eurotech suggests the following steps:
•When installing the device within a cabinet, rack or other enclosed space, be sure to leave sufficient
space to allow adequate air circulation
•Do not block any ventilation openings
Maintenance
DANGER!
•Never open, dismantle or repair the device!
•For your maintenance or repair requirement please contact a qualified Eurotech engineer.
If the device does not function correctly and you are unable to find a solution, feel free to contact

System reset
Connecting pin #9 to ground will perform a hardware reset of the CPU-1474/84.
You can use an external push-button (normally open) to manually reset the system.
The reset signal is “de-bounced” on-board.
External battery
An external (backup) battery is required to preserve Real Time Clock data when the CPU-1474/84 is
powered down.
Pin #7 allows the connection of an external battery.
The battery voltage must be between 3.0 V and 3.9 V.
Typical power consumption with the module off is 7 uA.
Speaker
A transistor that supplies 0.1W to an external speaker controls the signal output available on Pin #8.
A transistor amplifier buffers the speaker signal. Use a small general-purpose 2” or 3” permanent
magnet speaker with an 8-Ohm voice coil. The audio output is based on two signals: one come from
the output of Timer 2, and the other come from I/O port 61h compliant with the AT Standard.
The Eurotech multifunction adaptor
The Eurotech multifunction adaptor simplifies the connection of keyboard and mouse to the CPU-
1474/84
Furthermore it includes the following features:
•backup battery
•speaker
•reset button.
Please refer to the Technical Datasheet Td0026 (http://www.eurotech.com/DLA/AN/Td0026.pdf) for
further information.

Table 4. J5 Connector pinout
To install the hard disk, perform the following operations:
1. Install the hardware
Connect the hard disk to the module using a data cable, and then connect the hard disk to the
power supply according to the device’s specifications. Make sure that pin 1 of connector J5 and
pin 1 of the drive or drives are correctly connected. Pin 1 of the interface cable is usually indicated
by a stripe along the edge of the cable. If two hard disks need to be connected, they must be
configured for common operation (i.e. master/slave or cable select connection)
2. Configure the IDE BIOS setup
Hard disk parameters can be configured using the Setup program. If the hard disk is connected to
the module without the correct setup configuration (BIOS or Hardware), a time-out of a few
minutes may occur
3. Perform a software initialization (for specific operating systems)
Refer to the OS documentation
