•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
the Eurotech Technical Support Team.
If the equipment does not work properly, especially if smells unusual, unplug it immediately and
contact Technical Support Eurotech (see third and fourth cover of this manual for details).

WARNING!
Some Eurotech CPU modules (CPU-1421, CPU-1433, CPU-1233…) use address 110h, for this reason,
when you are using the COM-1274 with these modules ensure to select another free I/O address.
Otherwise your COM-1274 module will not work.
JP3: Reserved
This jumper is Eurotech reserved and must be left open.

COM-1274_UserMan_En_2.0
Important Note
Certain Eurotech CPU modules that have an ISA Bridge installed (CPU-1x33, CPU-145x and CPU-
146x etc), require users to open IO spaces within the CPU BIOS. This board requires the following
windows to be opened:
1. Board Base Address: 4 Bytes
2. Serial Base Address: 64 Bytes (8 Ports x 8 Bytes)
3. Serial IRQ Vector: 1 Byte
Therefore if the I/O address is 150h (JP1 Open and JP2 Closed), the Serial Base address is set to
280h and the Serial IRQ Vector is set to 2C0h, the ISA Bus tab in the CPU BIOS should include the
following:
•I/O Space 1 : Enabled Addr : 150h Size : 4 Bytes
•I/O Space 2 : Enabled Addr : 280h Size : 64 Bytes
•I/O Space 3 : Enabled Addr : 2C0h Size : 1 Bytes
Memory at 0D0000 .. 0D7FFF : ISA Bus (for the CAN interface, if required)
NOTE:
The “I/O space 1” above is only required to access the COM-1274 configuration software, and can therefore
be removed in a final system if access is not required

NOTE:
If the serial port is used in RS485 mode, the bi-directional line must be controlled via software, using the
Data Terminal Ready (DTR) signal of the serial controller.
This signal is defined by bit 0 of the UART Modem Control Register (MCR) and the bi-directional line is
controlled as follows:
•- bit 0 of the MCR register = 0 means RS485 line receiving
•- bit 0 of the MCR register = 1 means RS485 line transmitting
The I/O address of the MCR is "Serial port Base address"+4H
NOTE:
When you switch from transmitting to receiving mode, the serial port may receive an invalid spurious data
byte, thus it may be necessary to empty the serial port receive buffer immediately after setting the serial port
in receive mode.

COM-1274_UserMan_En_2.0
Installing the COM-1274
Stacking the COM-1274 with other PC/104 devices.
The ISA bus connectors on the module are designed to allow the module to be connected with other
PC/104 and/or PC/104Plus devices.
We recommend following the procedure below to ensure that stacking of the modules does not
damage connectors or components.
WARNING!
Always use appropriate antistatic precautions when handling the boards.
1. Turn off all power to the PC/104 computer and its peripheral devices.
2. Select and install standoffs to properly position the module on the PC/104 stack.
3. Remove the module from its antistatic bag.
4. Check that keying pins in the bus connector are properly positioned.
5. Check the stacking order; make sure an XT bus card are not placed between two AT bus cards as
this will interrupt the AT bus signals.
6. Hold the module by its edges and orient it so that the bus connector pins line up with the matching
connector on the stack.
7. Using even pressure press the module onto the PC/104 stack.
The figure below shows a typical module stack with two PC/104 modules, one PC/104 16-BIT module,
and one PC/104 8-BIT module.
The maximum number of modules is 4 in addition to the Host Board.
If standard PC/104 peripheral modules are used in a stack that includes a PC/104-Plus CPU module
and PC/104-Plus peripherals, standard PC/104 modules must be the top modules because they will
normally not include the PCI bus, while PC/104-Plus modules do.
