CAN-Bus connectors 527

Unless 10-line cables are used for the CAN-Bus, observe the following: Pins 1 and 2 are absolutely

necessary for transfer on the CAN-Bus. The CAN-Bus ground is also necessary. This may not be obvious,

but consider that differentially transmitted signals require a reference, for which reason a line connected

to the CAN-Bus ground must also be included. Either Pin 3 or Pin 6 can be used for this purpose.

Situations can also arise in which the CAN-ground is not needed: for instance, in a vehicle, where it is

possible to access Chassis potential anywhere, instead of using a line to Pin 3. In this case, Chassis simply

replaces the line to Pin 3.

Other lines can be included as required, for example a synchronization line or supply line.

Note also when using LEMO-plugs and the cables that there is a maximum current which LEMO-plugs can

carry. This particularly applies to the LEMO-plugs on the imc CANSAS-modules and the internal

connection of all of this plug's pins. The current should not exceed approx. 4,5A. It may be necessary to

use a correspondingly high supply voltage for the modules, or the separate terminal for the supply.

Also give regard to the cables' cross-sections.

8.1.3 µ-CANSAS CAN-Bus connections

Below is the pin configuration of the imc µ-CANSAS modules’ CAN-Bus connector. Connections of -AS

modules are made via 6-pin Autosport terminals of the type AS208-35SA (CAN IN) and AS208-35PA

(CAN OUT). Special tools exist for the purpose of assembling the Autosport connectors. More information

is available here.

Connections of -L modules are made via 5-pin LEMO terminals of the type HGG.0B.305.

Here, only the deviations from the normal housing types are presented.

For a general description of the CAN-bus refer to CAN-Bus description .

Note

Per default imc µ-CANSAS modules imc µ-CANSAS-V1, imc µ-CANSAS-T1 and imc µ-CANSAS-B1

come without an internal terminator resistor. This means to work connected directly to a imc µ-

CANSAS-HUB4-AS they need extra terminators. If you order the module with integrated

terminator, you wont need extra terminators when connected to a HUB4. In this case such a

module can only be used as the last module in the CAN-Bus, since it necessarily terminates the

CAN-Bus.
