Bus termination.
If the MAC00-FC2/FC4 is the last device on the CAN bus the module have a build-in ter-
minator of 120 ohm. The dip switch (SW2) is used to enable termination. When both
switches are on, the termination is enabled. In order to guarantee perfect operation of
the CAN bus, bus terminating resistors must be provide at both ends of the bus cable.
The figure below shows the termination selection:
The factory default settings are OFF on both dip switches, an the line termination are off.
CAN bus connectors:
The MAC00-FC2/FC4 are not using 9-pin D-sub connectors and none of the cables JVL
supplies are provided with 9-pin D-sub, but the PIN configuration is also shown in table
below.
On the next page are there drawings off the 9-pin D-sub and the 5-pin style connector.
