SubNet ID

The DDAA1000/SRM series modems offer a SubNet ID system for use in multi-point networks using Network ID. This feature allows the users to dictate what path a given repeater or remote will use to achieve a link to the network master. For example, if a remote modem in a given network has line of sight to the network master and one or more repeaters, but only one repeater is close to that remote, SubNet ID can be used to link that master with the proper repeater only.

Note: This feature can only be used in networks using Network ID with one or more repeaters.

There are two components to SubNet ID. The first is the Xmit (transmit) SubNet ID, and the second is Rcv (receive) SubNet ID. The Xmit SubNet ID is used only by repeaters and is the ID that a repeater sends out when sending data to other repeaters or remotes. The Rcv SubNet ID is the ID that repeaters or remotes look for to receive data.

Note: The master is not affected by these settings. Only repeaters and remotes use these settings. Remotes only use Rcv SubNet ID

Modem configurations are as follows:

Master	No setting used
Repeaters	Any repeater that should be linked directly to the master should have the Rcv SubNet ID set to 0. Any
	repeater using another repeater as its link, needs the Rcv SubNet ID set to the Xmit SubNet ID of that
	repeater. The Xmit SubNet ID can be set to anything from 1 to E.
Remotes	Any remote that should be linked directly to the master should have the Rcv SubNet ID set to 0. Any
	remote using a repeater as its link should have the Rcv SubNet ID set to the Xmit SubNet ID of that
	repeater
