Select and send the appropriate application file in HyperTerminal. The procedure for updating an

application file through a serial connection is the same as updating the BootWare program. For details,

refer to section Updating BootWare Through a Serial Connection on page 5-10.

Typically, the size of an application program is over 10 MB. Even at a serial baud rate of 115,200 bps,

the update takes about 30 minutes. Therefore, you are recommended to update an application program

through an Ethernet port.

Updating Applications Using TFTP

To update a large application file, use the Trivial File Transfer Protocol (TFTP), which can remarkably

shorten the software maintenance time.

TFTP is a TCP/IP protocol used for file transfer between client and server. It provides a simple and

low-overhead file transfer service. TFTP provides unreliable data transfer over UDP and does not

provide any access authorization and authentication mechanism. It employs the timeout retransmission

method to implement best-effort delivery of data.

The WX3000 series provides TFTP Client service. That is, with the device serving as the TFTP client

and the file server serving as the TFTP server, you can upload application files from the device to the file

server, or download application files from the file server to the device.

You can update an application file using TFTP through either the BootWare menu or the CLI.
