Hardware Installation
2.2 Execute Hardware Installation and Setting of PC/104-Bus Address
The CAN-PC104/331 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.
NOTICE
Read the safety instructions at the beginning of this document carefully, before
you start with the hardware installation!
DANGER
Hazardous Voltage -
Risk of electric shock
due to unintentional contact with
uninsulated live parts with high voltages inside of the computer into which the CAN-
PC104/331 is to be integrated.
→ Disconnect all hazardous voltages (mains voltage) before opening the computer.
→ Ensure the absence of voltage before starting any electrical work.
NOTICE
Electrostatic discharges may cause damage to electronic components.
In order to avoid this please follow the instructions below before touching the CAN
module:
→ Switch off the power supply of your computer but leave it connected to mains to make
sure that the computer case remains earthed.
→ Then touch the metal case of the computer to discharge your static electricity.
→ Furthermore, you should prevent your clothes from touching the CAN-PC104/331,
because your clothes might be electrostatically charged as well.
Procedure:
1.
Switch off your computer and all connected peripheral devices (monitor, printer, etc.). Switch
off the connected CAN devices of the network the CAN module is to be connected to.
2.
Discharge your body as described above if not yet done.
3.
Disconnect the power supply of the computer from the mains.
DANGER
Hazardous Voltage
Risk of electric shock
due to unintentional contact with uninsulated live parts with
high voltages.
→
→
→
Disconnect all hazardous voltages (mains voltage) before opening the computer.
If the computer does not have a flexible mains cable, but is directly connected to
mains, disconnect the power supply via the safety fuse and make sure that the
fuse cannot switch on again unintentionally (i.e. with caution label).
Ensure the absence of voltage before starting any electrical work
4.
Remove the computer cover.
5.
Select a free 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.
Make sure that there will be no address conflict with other PC/104 boards. (See chapter
'Before Starting Hardware Installation' above.)
