Removable CF Storage Media Cards
Overview of the available storage media
Operating conditions - removable CF storage media
condensation allowed (extended temperature range)
5.1.4 Field bus cabling
5.1.4.1 CAN, CAN FD cabling
imc C-SERIES is equipped with 2 to 8 nodes which are joined up by a tee-junction. Connect the tee-
junction to the 9-pin DSUB plug.
imc C-SERIES with connected tee-junction
Note that for a transfer rate of 1 Mbit/s to the CAN-Bus the stub line of a tee-junction may only be up to
30 cm long. In general, the wiring within imc C-SERIES is already 30 cm long. Therefore if an external tee-
junction is connected, the junction must be connected straight into the terminal.
In this context it doesn't matter whether the other sensors are connected via tee-junction or not. The
illustration simply shows the options available.

Please finde in the following chapter the technical specs and
·
in the following chapter the DSUB-9 pin configuration .
Connecting the terminators
·
Terminator-resistance is 120 Ω as per CAN in Automation (CiA).
·
If terminators are connected, then between Pins 2 and 7.
·
Terminators are only applied at the ends of the bus; nowhere else in the line. The bus must always
end at a terminator.
With High-Speed CAN a termination on each node can be activated by software.
