Command Descriptions, Continued

“events” Command

“dn” Command

5.After you have selected the “hub_rom.mot” file and click on “OK,” HyperTerm will begin transmitting records to the Hub. The Hub will respond by periodically displaying addresses as the file downloads.

6.After approximately 5 minutes, the download will be complete. The hub will display messages indicating that the download has com- pleted, and it is erasing and programming the FLASH memory.

7.Finally, the Hub will reset, and display a new login prompt.

This command controls logging of hub software events. Software events mark the progress of the Hub software in some detail so board problems may be more easily analyzed. The events off command will stop the logging of event messages. The list command, as described above, is used to view the software events in the event buffer.

This command may be used to override default values for several pa- rameters related to the HDLC protocol used by DataNET. Specific forms of the command are:

dn setuptime	Displays the current “setup time” value,
	in microseconds. This is the time that the
	hub will transmit a “preamble” pattern on
	a DataNET link before starting the actual
	data frame. The preamble allows time for
	the receiver circuitry at the far end of the
	link to adjust to the incoming signal’s
	amplitude, phase, and frequency. The
	default setup time is 3500 microseconds.
dn setuptime time	Sets the HDLC setup time to the value
	given, in microseconds. The new setup
	time value is saved in non-volatile mem-
	ory.
