on the instrument. In addition to the analog connectivity touch
screen control, Ethernet LAN/WAN connectivity, USB host client connectivity,
serial RS232 connection, IrDA connectivity, memory interface (SDCard,
mass storage), audio decoding were the other features required in
the device. The instrument was to be accessible for remote configuration
and monitoring. The GUI had to meet palm top / pocket PC based standards.
Standard Microsoft features that exist on a palm or pocket PC were
to be made available. The instrument had seven different configurations
