Appendix A Firmware Upgrade Procedure

The latest firmware for Moxa’s embedded computers can be downloaded from the download

center on Moxa’s website. For the UC-7122/7124, we provide a solution to upload the firmware

file by TFTP, and upgrade the firmware using boot loader utilities. The following steps show how

to upgrade the firmware:

Setting up the TFTP server

1. Connect LAN1 of the UC-7122/7124 to your PC using a cross-over Ethernet cable.

2. Download a free TFTP server package from the following site:

ftp://papa.indstate.edu/winsock-l/Windows95/Daemons/TFTPD/

3. Refer the “Help” file in the package for instructions on how to set up the TFTP server.

4. Put the latest firmware image (e.g., UC7124_V1.0.07061112.bin) in the same directory that

the TFTP resides.
