Hello there,

who owns already an HP49G-device ???? Can you give some comments about this tool ????

Can this be true: There is NO Infrared-interface ????

Go to ( to answer all your question on the HP49G.

More specifically go to for the HP49G FAQ.

And yes there is NO IR port. They used the high output pin which used to drive the IR LED to control the Flash chip write voltage.
