Easy IP address config (UDP # 7010)
A really useful feature of the UDP port #7010 is the "Easy IP config" one.
The user who wants to design his own software can use this feature to do a
"quick start/install" method. Indeed, since this protocol uses a broadcast UDP
packet, even if the device is not in the same subnet, it should receive its new
IP address and subnet mask.
Procedure:
Send a UDP broadcast message (using a local or direct broadcast IP address)
to your network (inside which the FMod-TCP BOX is connected) with the
following command:
Byte# Number of bits Example
0x00 Change IP fct (0x002A) 16 bits 0x002A
0x02 TransactionID 16 bits 0x0000
0x04 Length of params (0x000E) 16 bits 0x000E
0x06 FMod-TCP BOX Mac Address 6 bytes 0x0050C2308101
0x0C FMod-TCP BOX new IP
Address
4 bytes 0xC0A81064
0x10 FMod-TCP BOX new
SubnetMask
4 bytes 0xFFFF0000
0x14 Checksum 16 bits 0x…
If the FMod-TCP BOX recognizes its MAC address, it will answer this
command with a simple acknowledges and change its IP address and subnet
mask IF NO TCP CONNECTION IS MADE TO THE DEVICE.
Byte# Number of bits Example
0x00 Change IP fct ack (0x002B) 16 bits 0x002B
0x02 TransactionID 16 bits 0x0000
0x04 Length of params (0x0000) 16 bits 0x0000
