Firmware Update - DekTec DTM-3200 User Manual

DTM-3200 – OEM Ethernet TSoIP Converter
User Manual
 The 0.0.0.0 IP address behavior mentioned before still applies, but the 'DHCP enable' setting
can now be used to turn on and turn off the DHCP client.
- When 1 is written to 'DHCP enabled', the IP address is set to 0.0.0.0 and (after a reboot)
the DHCP client will start looking for a DHCP server to acquire an IP address.
- When 0 is written to 'DHCP enabled', the DTM-3200 retrieves the most recently manually
entered IP-address (fixed IP) and uses this address as its fixed IP-address (after a reboot).
 When a fixed IP-address has never been entered before, writing 0 to 'DHCP enabled' w
cause the DTM-3200 to use a hardcoded factory default address (192.168.144.120 /
255.255.255.0) as its fixed IP address (after a reboot). Naturally this default IP address
selected by writing 0 to 'DHCP enabled', can be overridden by entering an IP address
manually.
The DTM-3200 must be rebooted before a new IP-address assignment takes effect. Rebooting the
device is initiated by writing 1 to the 'Reboot' setting, or by a power cycle.

4.4.5 Firmware update

To upgrade the DTM-3200, the new firmware has to be uploaded in "file parts". The firmw
update settings are used to upload the firmware file and control the programming process.

This category requires an index to be sent with each command. For the "File part" setting, index
should be the file part number. For the other settings, index is not used.
For communication through I
through RS-XXX the parts may contain at most 1024 data bytes.
For firmware version 1.3 and lower, each data byte was sent as 2 ASCII characters (1 character pe
nibble, using 0..9 and A..F), so 1024 data bytes were sent as 2048 ASCII characters.
To improve the firmware update speed this was changed into a different encoding.
