Host Software Upgrade Procedure
This section provides procedures for upgrading Integrated Access System host software. The 
procedures for upgrading from 1.0.0 to the next release.
The host software is stored in flash memory facilitating download of future software releases 
to the IMACS-200. 
The preferred upgrade method is using tftp protocol. The estimated time to upgrade an 
IMACS-200 with xmodem is 1.5 hours, whereas upgrading the unit with tftp takes 
approximately 5 minutes.
