4.4 Firmware Update
The GW-7472 supports firmware update through the Ethernet network with the
BOOTP/TFTP protocol. Generally, the firmware is not necessary to update when it works well. If
there are some bugs in the firmware of your GW-7472 or you need new functions which don’t
support in your GW-7472, the firmware update is necessary. If the firmware update procedure is
broken unfortunately, please try it again.
Before updating the firmware, you have to set
the “Init Switch” to “Init” position and then
re-power on the GW-7472. Since the flash becomes writable, we can update the firmware
through the Ethernet network.
Note:
1. Well configure the network settings of your PC. Or the update procedures through the
Ethernet network may not work correctly.
2. The program (TFTP server) may not run correctly if there is another TFTP server running
on the same PC.
3. The BOOTP and TFTP protocols use the Ethernet UDP port 67, 68 and 69. Please confirm
that the firewall of the Windows system or anti-virus software can pass these UDP ports.
