10.2.2
Fixed IP address
When using a fixed IP address, you must ensure that you use an IP
address that is not being used by any other device on the network. It
is usual to keep the first three numbers of the IP address the same as
other devices and to change only the last number. For example, if you
have a network consisting of a PC (IP address 192.168.1.35) and two
RTxxs could be allocated addresses 192.168.1.201 and 192.168.1.202.

Automatic sensing
All the features below are implemented in sample C++ source code

The RTxxx sends a message on three events:
i.
On power up
ii.
When an IP address is received or renewed by DHCP
iii.
When an enquiry message is received.
On the first two events, the message is broadcast. On the third it is a
reply to a single IP address.
An enquiry message is a UDP packet from source port 30310,
destination port 30311 with the message body ‘Gardasoft Search’ (8-bit
ASCII,
13 characters).
The message output by the RTxxx is a UDP packet from source port
30311, destination port 30310. It is formatted as:
Gardasoft,RT220-20,000000,111111111111,22222222
(8-bit ASCII, 44 characters) where,
000000
The serial number of the unit
111111111111
The MAC address in 6 HEX bytes
22222222
The IP address in 4 HEX bytes
For example; for RT220-20, serial number 12345, IP address
192.168.1.103, MAC address 00.0B.75.01.80.99 the packet is formatted:
Gardasoft,RT220-20,012345,000B75018099,C0A8016
