					SpaceWire Router		UserManual
					SpaceWire Router	Issue:	3.4
					User Manual	Issue:	3.4
					User Manual	Date:	11th July 2008


5.7.4			VCO bias resistor value corrected (Section 5.7.4).

8.1.5			Tri-state mode changed to deactivate mode. Calculation of
			deactivated power consumption added.

9.4.3		Table 9-6	Tri-state mode changed to deactivated mode.

9.5.8			Description for ‘time-code flag mode bit’ added.

11.1		Table 11-1	Power information updated.

11.3			Section added on reliability information

13.1			Reference to further details on anomaly 1 in section 13.3
			added.
			Anomaly 2 (tri-state mode) removed. The text throughout the
			document related to tri-state mode has been corrected to
			deactivated mode. A warning that the deactivated mode is not
			true tri-state has been added.

13.3			Section added to give more details on reset anomaly.

5.6			Second warning clarified.

7.6.10			Note added explaining that command packet fill bytes is a
			feature of the SpW-10X and not of RMAP.

8.1.6			Warning on setting data rate to less than 2 Mbits/s deleted.
13.2			The SpW-10X device will not allow a TXDIV and TXRATE to be
			set to give a transmit data rate below 2 Mbits/s.

8.3.2.4			Note added to further explain blocking of low priority packets by
			high priority ones.

8.3.5.3			Corrections made. When output port not running or in a group
			and not running, the router will waits for the timeout period for
			the link to start. If it does not start in that time then the packet
			will be spilt.

11.1			References to [AD3] corrected.

12.1			Example schematic changed to a format that is readable.
