How to set the device MAC addresses! How many MAC addresses are required?

There are 2 ways to provide one ore more individual MAC address to a netX 90 based device:

1. Stored in the FDL - flash device label - in the internal flash memory of netX 90
2. Provide the MAC addresses during boot from the host controller a) netX 90 APP side, or b) external host controller

In case of 1), each netX 90 based device requires an indivdual FDL. Please refer to the document "Production guide netX 90", chapter "Flash Device Label (*.fdl)" for more information.

For 2), the mailbox packet service "Device Data Provider Set service" can be used. This service is described in the manual netX Dual-Port Memory Packet-based services (netX 90/4000/4100)

Number of MAC addresses

The number of required MAC addresses depends on the used protocol stack. Please refer to the respective Protocol API manuals for further information.
