Source Address field, the Type field, and the Data field. When setting a
filter, you can use these fields individually or in combination.

its default value of all Xs in all fields. If enabled, the NB30 will filter all
network traffic passing through it.

field that alternately displays YES and NO when you press Return.

or Relay.
