Use this command to load new software into the device via the RS-232
Configuration port. The procedure for software download is:
1. Make sure you have a “ANG_DNCP.mot” file available for download.
2. Log into the target ANG_DN board through the RS-232 port, using
HyperTerm.
3. Type “download” at the prompt (“>”). The device will print some mes-
sages and then prompt to begin transmitting the download file.
4. Transmit the download file. Use the HyperTerm “Transfer --> Send
Text File…” command. Find the “ANG_DNCP.MOT” file using the
browser window. You will have to select “Show all files” in the “Files
of type” window to see the “ANG_DNCP.MOT” file.
5. After you have selected the “ANG_DNCP.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 down-
loads.
6. After about 4 minutes 30 seconds, the download will be complete.
The hub will then display messages indicating that the download has
completed, and it is erasing and programming the FLASH memory.
7. Finally, the Hub will reset, and display a new login prompt.
