2.2.2

Configuration Through the Network

Additional items configured using this feature. The configuration is performed with an INITIAL SETTING

packet received from the host node.

If the default is acceptable for all items that require configuration via the network and the NST carry output

(i.e. nNSTCOUT described later) is not used, then configuration by the INITIAL SETTING packet is

unnecessary. The configuration by INITIAL SETTING packet is valid only before receiving the START

TRANSMIT command (described later). After receiving the START TRANSMIT command, the INITIAL

SETTING packet is ignored.
