Overview
1. Overview
1.1 Descri tion of the Module
Figure 1: Block circuit diagram of PMC-CA /331-3.3
The module PMC-CA /331/3.3 uses a 68331 micro controller, which cares for the local CA data
management. The CA data is stored in the local SRAM. Security and consistency of data is
guaranteed up to 1 Mbit/s.
The ISO11898-compliant CA interfaces allow a maximum data-transfer rate of 1 Mbit/s. Among
many other features of the CA interfaces, the bit rate can be set by software.
The CA interfaces are electrically isolated from the other potentials and from each other by
means of optocouplers and DC/DC-converters.

Hardware Installation
2. Hardware Installation
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 PMC-
CA /331-3.3 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 com onents.
In order to avoid this please follow the instructions below before touching the CA
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 PMC-CA /331-3.3,
because your clothes might be electrostatically charged as well.
The PMC-CA /331/3.3 module can be used on various carrier boards, therefore, the carrier
system will generally be called ‘computer’, below.
Procedure:
1. Switch off your computer and all connected peripheral devices (monitor, printer, etc.). Switch
off the connected CA devices of the network the CA module is to be connected to.
2. Discharge your body as described above.
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. Open the case.
5. Plug the PMC-CA /331/3.3 module onto a suitable carrier board.
Connect module and carrier board by means of screws. Use the four M2.5 x 6 mm screws
which are contained in the product package of the module.
6. Install the carrier board into your system.
7. Close the computer case.

Hardware Installation
8. Connect the CA wire.
NOTICE
To sustain the compliance with directive 2004/108/EC, it is necessary to use four-
wire twisted pair CA cables.
Please note that the CA line must be terminated at both ends.
Additionally, the CA _G D must be connected to earth at exactly one point in the CA
network. Use the special T- connectors and terminator connectors offered by esd.
A CA device whose CA interface is not electrically isolated acts as an earth connection
like the CA _G D.
Please ay attention to the notes on correctly wiring of CAN networks (see from age
25)!
The first CA interface (CA network 0) is connected via the DSUB connector (X400) and
the second CA interface (CA network 1) is connected via the DSUB connector (X401).
9. Connect the computer to mains again (mains connector or safety fuse).
10. Switch on the computer, the peripheral devices and the other CA devices again.
11. End of hardware installation.
Continue with the software installation as described in the manual ‘ TCA -API, Installation
Guide’.

Configuration Resistors
4. Configuration Resistors
By changing the resistors equipped, the assignment of the local CA interface and the PMC-
connector P14 can be changed. In order to do this, existing resistors have to be removed and new
ones have to be equipped.
NOTICE
Any intervention in the device by unauthorized persons voids warranty claims!
It is therefore recommended to send the PMC-CA /331-3.3 to esd for the change of the
resistors. The changes can be made by esd for your expense. Please contact our
support.
4.1 Com arison of Different Signal Assignments
Signal assignment 1 (com onent equi ment 1 / =default equi ment):
In the default version of PMC-CA /331/3.3 the CA signals of the CA controller are assigned to
the local ISO11898-interface (DSUB9). Only the G D-signals are assigned to P14.
Signal assignment 2 (com onent equi ment 2):
Alternatively, the unidirectional CA signals of the controllers can be assigned to the connector
P14. Assigning the signals to P14 and the DSUB-connectors at the same time is not permitted.
Signal assignment 3 (com onent equi ment 3):
Another alternative is to assign the connector P14 with differential CA signals of the controllers.
For this matter the controller has to be especially configured, because it drives the ports
unidirectional in standard configuration.
