Note 1: Broadcast messages pass through both ports simultaneously,

whereas point-to-point messages go out a single port, based on the

address information.

Note 2:

This affects only the configuration of the IP settings of an

FP-1600/2000/2010, but does not affect normal communications.

After configuration, you can use two ethernet cards on a single computer

to communicate to a FieldPoint network module, but only if the cards are

configured with mutually exclusive subnets. This is because point-to-point

communications are transmitted out single ports based on the subnet

masks for the network cards. During configuration the FieldPoint network

modules are not assigned IP addresses, so broadcast messaging is used

through both ports.
