Details

 

When Broadcast UDP is 1 (enabled), the DS will accept and route the data received in broadcast UDP datagrams, as if these packets were addressed directly to this DS. Broadcast packets must still be addressed to the correct Port Number (PN). DS will ignore broadcast UDP packets when Broadcast UDP is 0 (disabled).

 

This setting only allows/disallows the reception of broadcast UDP packets and has no influence over whether the DS can send out its own broadcast UDP datagrams or not. The DS can be made to send the broadcast packets by setting current Destination IP-address (IP) [setting/ parameter/ instruction] to 255.255.255.255.

 

This Setting is irrelevant when current Transport Protocol (TP) [setting/ parameter] is 1 (TCP) because TCP protocol cannot use broadcast packets to carry data.
