2.3 Connections
2.3.1 CAN connection for the PC
The access for CAN to the PC is provided via an ISA-bus card, PCI-bus card, PCMCIA-card, or a USB or
parallel port adapter.
To install the card or adapter, please observe the notes and instructions in the booklet which comes with
the card and use the corresponding driver diskette. Alternatively, the driver software located under the
folder
\Driver\..
on the imc CANSAS-CD-ROM can be used, as described at the beginning of this chapter.
However, it is possible that the driver installation on the imc CANSAS CD doesn't represent the most
current version of the card driver.
2.3.2 CAN connection to CANSAS
The imc CANSAS-module possesses a full-grade CAN (Controller Area Network) connection for
transmitting measurement data, and can send messages at up to 1MBit/s. The CAN-connection is a node
on the CAN-Bus, to which any number of CAN-devices can be connected.
The CAN-Bus can be considered a sort of line. The beginning consists of a CAN-Bus-terminator, which is
connected to the first node either directly or via a serial cable. The second node is connected to the first
via another serial cable, etc. After the last node, there is another CAN-Bus-terminator.
The serial cables used are commercially available, plated-through cables for the PC's serial interface.
A special CAN-Bus terminator can be ordered which runs up the module in its original state, without any
configuration. This makes it easily possible to reconfigure the module if it ever becomes impossible
otherwise.
2.3.3 CANSAS analog connections
The imc CANSAS-module's measurement input connections consist of two sockets for two separate sets
of measurements. Depending on the module type, either four or six differential channels can be
connected. For ease of connecting, special imc plugs having screw terminals can be ordered. The pin
configuration and measurement process are described in the appendix.
2.3.4 Checking connections
A dialog called from the menu item in the imc CANSAS interface's ‘EXTRAS’ menu lets you make settings
for the CAN-Bus access and for interface parameters. Details are available in Chapter "Operation" -
Extras/ Interface
and in the booklet or diskette about the interface-card.
The integration assistant can integrate and configure
both available and not yet available modules.
