28 Pin configuration
3.1.4 µ-CANSAS with Autosport or LEMO
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.
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.

Pins 3 and 4 are absolutely necessary for transmission on the CAN-Bus, as
well as the CAN-Bus ground. According to specifications, the differential
signals require a reference, for which reason a CAN-Bus ground connection
is also needed. For this purpose pin 6 can be used. There are situations
where the CAN ground is not necessary: for example, on board vehicles, if
instead of a line to pin 6 it is possible to make contact with anywhere on the
chassis. In that case, the chassis is a substitute for the line to pin 6.
Other lines can be used for the purpose if necessary, for instance the
power supply line.
Note when using Autosport plugs and cables, that there is a limit on the maximum current through the
Autosport-plug. The current should not exceed approx. 5A. An accordingly high power supply voltage for
the modules may need to be used. Check the cross-section of the cables.
