1. Overview
1.1 Module Description
Fig. 1.1.1: Block-circuit diagram of the DN-PC104/331 module
The DN-PC104/331 board is a designed for the PC/104-bus (PC/104 16 bits). It uses a 68331
microcontroller, which cares for the local management. The DeviceNet data is buffered in a local
SRAM. Security and consistency of data is guaranteed up to 1 Mbit/s.
The DeviceNet compliant interface allows a data-transfer rateof a maximum of 1 Mbit/s. Among
many other features, the bitrate can be set by software.
The DeviceNet interface is electrically separated from other voltage potentials by means of
optocouplers.

2. Hardware Installation
2.1 Before Starting Hardware Installation
During the hardware installation it may be necessary to change the PC104-I/O-port address. The
default address is 1E0...1E7 HEX. The DeviceNet module covers 8 data bytes. Furthermore it
is necessary to set the interrupt during the following software installation.
Make sure that there will be no address conflict with other boards of the PC/104-system
and that there will be no conflict with other interrupts!
Note for Windows 95 Users:
If you use a Windows 95 operating system first read the software installation guide in the
appendix of the manual ‘CAN API, Monitor Program CAN-Scope and Installation’ and then
start with the installation sequence!
2.2 Execute Hardware Installation and Setting of PC/104-Bus Address
The DN-PC104 module can be used in all PC/104-compatible 16-bit systems (e.g. portable
industry PCs or installed control systems). The carrier system will therefore be described by the
general term ‘computer’ below.
Attention !
Electro static discharge may cause damage to electronic devices. To avoid this, first do the
following steps to discharge your personal static electricity, before you touch the DeviceNet
module:
@Switch off the power supply of all units but leave the connector plug in the socket.
@Then touch the computer’s metal case to discharge the static electricity.
@Even your clothes must not touch the DeviceNet module!
1. Switch off the computer and all connected peripheral devices (monitor, printer, ...). Switch
off the other DeivceNet participants to that the PC104 module is to be connected.
2. Discharge yourself as described above if not yet done. @@

3. Disconnect the computer from mains by removing the mains connector.
If the computer does not have a flexible mains lead but is fixed to the mains, disconnect the
supply voltage via the safety fuse and protect the fuse from switching on again
unintentionally.
4. Remove the computers cover
5. Select a position in the PC/104-bus stack.
There are no restrictions in choosing a position in the stack for this module as long as there
are only 16-bit modules between it and the CPU.
6. Haveyou made sure that there will be no address conflict with other PC/104 boards? (See
chapter '2.2.1 Before Starting Hardware Installation' above.)
If you have to change the address of the board, go on with step 7 otherwise go on with step 8.
7. Setting the PC/104-bus-I/O-port address
Theaddress is set via the DIL switch S100. Its position can be taken from figure 1.2.1 on
page 4.
If a coding switch is set to ‘OFF’, the according address is evaluated as ‘1’. If it set to ‘ON’,
the according address is evaluated as ‘0'.

The hardware address has tobe given to the driver during the software installation. The menu
of the Windows NT installation program e.g. offers a choice of the following addresses:

Note: The Windows NT installation program does not support any other coding switch
positions.
8. Install the DeviceNet module at the selected PC/104-stack position.
9. Close the computers case.
10. Connect the DeviceNet.
Please note that the DeviceNet has to be terminated at both ends by resistors. Consult the
DeviceNet Specification for the correct wiring of the net.
11. Connect the power supply of the computer (mains connector or fuse).
12. Switch on the power supply of the computer, the peripheral devices and the other DeviceNet
participants.
13. End of hardware installation.
Continue with software installation.
