System reset
Connecting pin #9 to ground will perform a hardware reset of the CPU-1452/62.
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-1452/62 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-
1452/62
Furthermore it includes the following features:
• backup battery
• speaker
• reset button.

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)

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

Stacking the CPU-1452/62 with other PC/104 and PC/104-Plus devices
The ISA and PCI Bus connectors of the CPU-1452/62 are located on the bottom side of the Carrier module only, and are designed to allow the connection on the top position of the stack formed by other
PC/104 and/or PC/104-Plus 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 device and its peripherals.
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 module stack with the CPU-1452/62 on the top of two PC/104-Plus modules.
If standard PC/104 modules are used in the stack, they must be the lowest modules because they will normally not include the PCI bus. An adapter module must be used.

BTOOL is a utility used to update the BIOS Flash EPROM; it can be used for the following tasks:
•
Upgrading the BIOS
•
Installation of a MiniDOS compatible program into the Flash (Integrated SSD)
•
Installing a BIOS Extension onto the flash device
WARNING!
The BTOOL program should only be run in the MS-DOS environment, not a DOS WINDOW.
During the creation of a bootable MS-DOS floppy disc the following precautions should be taken into consideration:
•
Power assured during all the program executions.
•
AUTOEXEC.BAT and CONFIG.SYS should not have any parameters
•
No memory manager should be loaded.
•

A portion of the Flash EPROM can be used as an Integrated Solid State Disc (SSD). This Integrated
SSD is like a write-protected floppy disk.
Depending on the CPU module used the size of this disc may vary, before use data needs to be written to it using the BTOOL program.

SSD Size
768 KB
EXAMPLE 2: Creating an image of a floppy disk into the
Integrated SSD
1. Create the “image disk”, copy any files and directories that you require
2. During this copying process take care not to delete any files or data from the floppy disc, doing so will create empty sectors and these will be mirrored onto the SSD, wasting space.
3. Take care not to exceed the SSD Size (refer to Errore. L'origine riferimento non è stata trovata.
)
4. Type the following command at the DOS prompt (BIOS.BIN is only an example filename, check the name of the file that came with the download)
•
BTOOL /DA BIOS.BIN
5. The program will ask you to insert the “image disk” into drive A
6. Follow all the instructions the BTOOL gives you: the program will proceed by erasing the Flash device blocks and then writing and verifying them with the data present on the “image disk”
7. BTOOL will inform you about the result of the operation
8. Once completed cycle the power to finalise the operation
NOTE:
You may need to enter the Setup programme using F2 during the boot sequence to configure the system as required (for example setting up the SSD as a boot device).

Virtual Peripheral
Virtual Peripheral
Eurotech CPU Modules are designed for use in stand-alone mode i.e. without keyboard, mouse, video or other I/O peripherals connected.
Therefore to simplify maintenance operations, users can easily make I/O peripherals available by using “Virtual Peripheral” mode, by doing this the CPU Module inherits the I/O peripherals from another compatible computer (called the Host computer ) connected through a serial cable. To make this possible, the VP2000 DOS program must be running on the Host computer .
How “Virtual Peripheral” works
The “ Virtual Peripheral ” is a software solution implemented at BIOS level. BIOS service functions called to handle the keyboard, video and floppy disk devices, are converted into messages forwarded to the Host computer through the communication channel using a proprietary packet protocol.
When the Operating System or the user’s program deals with the keyboard, video or floppy disk drive, it actually deals with host computer’s devices. There are no hardware traps to intercept accesses to these devices, so Virtual Peripheral works only if operating system and application programs use BIOS calls to work on them without directly accessing the relative I/O ports and memory areas.

CPU-1452/62 User Manual
Choosing the Virtual Peripheral connection type
On CPU-1452/62 the Virtual Peripheral session can be only performed via a Serial connection.
Serial Connection:
•
Requires a RS232 RX/TX cable (with special wiring on CPU end of the cable)
•
Connection is made at 112000 bits/sec.
•
Connection works on any CPU serial port that is configured for RS232 mode.
•
In case of bad configuration data, or if the invalid set-up is running, VP connection works only on the port that only supports RS232 (this avoids troubles if RS422/RS485 devices are connected).
The following illustration shows how to make a Serial VP cable connection:

How to perform a Virtual Peripheral session
To perform a Virtual Peripheral session you will need:
•
A free Serial Port configured as RS232 on the CPU module.
•
If invalid configuration or the invalid set-up jumper is installed, you must use only one of the
Serial Ports that are RS232 fixed (not RS232/422/485 selectable).
•
The appropriate Serial VP cable
•
A PC compatible computer to be used as host, this computer must have a free RS232 Serial
Port
•
The Host Computer must be running DOS Operating System. If not available on its hard disk, you must create a DOS floppy disk and then boot from it. Do not put any memory manager or keyboard driver on that floppy.
•
The Eurotech VP2000 program, Save it on the hard disk or on the just created floppy disk.
Follow these steps to perform a Virtual Peripheral session:
1. Make sure the CPU Module and the host computer are switched off.
2. Connect the CPU Module and the host computer together using the VP cable.
3. Turn the host computer on and boot DOS.
4. At the DOS prompt start the VP2000.exe program using the command line options as listed above in order to choose the Serial Port you want to use and the peripherals you want to connect to the
CPU.
5. Turn on the CPU Module. Note that when you turn on the CPU Module, the VP2000 program must be already running on the host computer. If you start running the VP2000 program later, the
Virtual Peripheral connection will not work.
6. If you have chosen to redirect the Video, then CPU Module’s video output will be redirected to host computer screen where you will see the CPU BIOS Banner and POST information.
7. If you have chosen to redirect the Keyboard, then you must use the host computer’s keyboard to enter set-up pressing ‘F2’ or to continue boot pressing ‘F1’.
8. If you have chosen to redirect the Floppy Disk, then CPU Module will see host computer Floppy
Disk as its own Floppy Disk ‘A:’ If you have a disk inserted into host computer drive, the CPU
Module will try to boot from it
9. To exit VP2000 program press the ‘Print-screen’ key.
10. You can hardware reset the CPU Module or recycle its power without exiting and restarting
VP2000.
WARNING!
During a Virtual Peripheral session:
•
Do not press the ‘Ctrl + Alt + Del’ key combination on the host computer’s keyboard: the result will be a reboot of the host computer, not of CPU!
•
Do not use the DOS “format” command under Virtual Peripheral mode: it will not work.
•
Do not disconnect (and then reconnect) the communication cable: the hardware might be seriously damaged!
•
Remember that Virtual Peripheral is only intended for maintenance and upgrade operations: if you need a remote operative console, Virtual Peripheral is not a good solution.

Configure the Watchdog timer
Configure the Watchdog timer
The Watchdog Timer is a computer hardware countdown that triggers the board reset if the main program, due to some fault condition, such as a hang, neglects to regularly refresh the watchdog. The intention is to bring the system back from the unresponsive state into normal operation.
NOTE:
In the CPU-1452/62 the watchdog is a part of the on–board SUPER I/O device PC87364
The Super I/O registers allow you to manage time-outs in order of seconds or minutes, depending on the Super I/O programming.
Watchdog programming modes
There are two ways of programming the watchdog:
•
Using the BIOS INT 52h programming mode
•
Using the Super I/O registers programming mode
BIOS INT 52h programming mode
This method can be used under DOS or under Operating Systems using the board BIOS (i.e. not under Linux which erases the BIOS after the boot and autonomously manage the module hardware).
The functions implemented from the BIOS are:
Function
Enable the watchdog
Meaning
INT 52h, function 00Ch Watchdog enabled with a fixed time of 2 seconds.
This function programs and starts immediately the watchdog counter.
Refresh the watchdog INT 52h, function 00Eh Watchdog refresh.
Every call to this function restarts the counting from the initial value
Disable the watchdog INT 52h, function 00Dh Watchdog disabled.
Counting is interrupted and watchdog disabled
When the watchdog is activated, the countdown starts immediately. If no refresh occurs, when the default timeout expires, the board reset is executed. Therefore, the watchdog must be enabled and continuously refreshed, avoiding in this way the board to be reset.
Example: Enable the watchdog
MOV AH, 00Ch
INT 052h ; Enable the watchdog (fixed timeout = 2 seconds)
Example: Refresh the watchdog
MOV AH, 00Eh
INT 052h ; Refresh the watchdog
Example: Disable the watchdog
MOV AH, 00Dh
INT 052h ; Disable the watchdog

CPU-1452/62 User Manual
Super I/O registers programming mode
This method must be used when the OS doesn’t manage the BIOS (i.e. Linux) or when a personalized watchdog programming is required.
