2. Typical Applications

The AT7910E SpaceWire router is perfectly suited for development of applications requiring a standalone router, a

terminal node with SpaceWire interface or a mixed configuration of the two previous ones.

2.1 Stand-alone router

The AT7910E SpaceWire Router may be used as a stand-alone router with up to eight SpaceWire links connected to it.

Configuration of the routing tables etc. may be done by sending SpaceWire packets containing configuration commands

to the router.

2.2 Node interface

The SpaceWire Router has two external ports which enable the device to be used as a node interface. The equipment to

be connected to the SpaceWire network is attached to one or both external ports. One or more SpaceWire ports are used

to provide the connection into the SpaceWire network. Unused SpaceWire ports may be disabled and their outputs tri-

stated to save power. In this arrangement configuration of the routing tables and other parameters may be done by

sending configuration packets from the local host via an external port or from a remote network manager via a SpaceWire

port.
