AXIOMATIC AX140900 - CAN ID Mask Filters

UMAX140900. Ethernet to CAN Converter. Version 5 Page: 16-35
Once the filter is activated by checking the On/Off box, the CAN input messages will pass
through to the Ethernet network only if their CAN ID is within the range specified by From and
To configuration parameters.

To configuration parameter.
The EID box (Extended ID box) defines whether the CAN message ID is regular or extended.
All CAN ID range filters run in parallel. It is sufficient to satisfy requirements of any active filter
to pass the CAN message to the Ethernet network.
If no active filters are defined, it is considered that the CAN ID range filters are disabled, and
do not participate in the message filtering process. In this case, ID Range Filters are Off on the
home page, and, if other filters are also disabled, all CAN input messages will be sent to the
Ethernet network.

The CAN ID mask filters are set through the CAN ID Mask Filter configuration web page.
