In order to change the firmware manually,
you must first download the above firmware file and save it to a local
disk. LynxNets also support remote update. To
get firmware updates please call tech support with the MAC address of

it remotely. If not, well......., connect a serial cable to a laptop or a
PC.
Locate the RS-232 connector on the front panel
of the system.
Plug the RS-232 programming cable in it.
Connect this cable to a COM port in the PC or
laptop.

2) Hyper Term will then ask
which COM port you plugged the cable in.
(Typically COM1 or COM2).
