Please note that the product names for PCIcan-S, -D, -Q changed to PCIcan-HS, -HS/HS, -
4XHS during 2004/2005. This change was necessary due the introduction of PCIcan boards
with low speed and single wire CAN bus drivers. In addition, the part number was shortened
to the 6 last digits due practical reasons. However, both part numbers are valid. These
changes affect the product name and the part number only. The product itself is identical in all
other aspects.
2.1 Not recommended for new designs
NOTE:
The PCIcan devices listed in the table above are not recommended for new
designs.
Instead, we recommend our PCIcanx devices, which are fully software compatible
with the PCIcan devices. The PCIcanx devices are described in another document; please
refer to our web site.
2.2 General Description
KVASER’s PCIcan cards for CAN systems feature up to four CAN controllers.
The outputs from the CAN circuits are connected to a 25 pin DSUB (PCIcan-Q) or one or two
9-pin DSUB (all other types) via optocouplers and CAN bus driver circuits.
The bus driver circuits of type 82C251 conforms to the physical layer specified by the ISO
11898 standard and can operate up to 1 Mbit/s.
The bus driver circuits of type 5790 conforms to the physical layer specified by the SAE 2411
standard and can operate up to 25 kbit/s in normal mode and up to 80 kbit/s in high-speed
mode.
The bus driver circuits of type TJA1053 are intended for automotive body electronics buses
and can operate up to 125 kbit/s.
On the PCIcan-Q it is possible to connect all CAN circuits to a common CAN bus, which also
is connected to the DSUB connector. A built-in terminator may be connected to the common
bus if this board is at one end of the bus cable. It is necessary to have a resistor load
connected between the two bus wires to make the ISO 11898 drivers work. The 25-pin
connector also provides a ground point to the two bus sections of optocouplers and drive
circuits.
