Communication Protocols - 4Links Multi-link SpaceWire Recorder Version 4 User Manual

2.6. Communication Protocols

4Links EtherSpaceLink units provide access to a SpaceWire network from computers on a conventional TCP/IP
Ethernet network. TCP/IP is used over Ethernet to provide an error checked guaranteed delivery system, even
through noise or the intervening network failing and being restored (for example, a cable being removed and
reconnected).
In the event of an EtherSpaceLink unit being powered down, the computer will expect the connection to be
restored, but the EtherSpaceLink unit will have lost connection information and the computer application
program will have to be restarted.
Similarly, a failure of the computer will leave the EtherSpaceLink unit waiting for a connection restoration that is
not possible, and in this case the EtherSpaceLink unit must be reset, by cycling power or by removing and re-
inserting the removable memory card on its front panel.
