Why does the session time out when downloading a configuration file via HyperTerminal to my 4xxx or 5xxx Series ProLinx Gateway?

Selecting and confirming from the module menu just prepares the module to receive a configuration file. To actually accomplish the configuration file download, you must select send file from the transfer menu in hyperterminal, browse to the filename.cfg file, select it, pick the transfer protocol and click the send file button. this will actually send the configuration file to the module waiting to receive it.

Note: choose "y-modem" as the transfer protocol.
