IP Change Trap
CSE-H21 has a function to send its IP address. So user can solve the problem that IP address is
changed automatically in the dynamic IP address environment. CSE-H21 supports 3 kinds of
transmitting methods – DDNS with DynDNS, TCP and UDP.
4.4.1
DDNS
– www.dyndns.com
DDNS(Dynamic DNS) is a system that communicates by the hostname that is registered to a
DNS server after registering the IP address in the dynamic IP address environment. The DDNS
function that is supplied by CSE-H21 is that CSE-H21 registers its IP address to the DynDNS
Inc.(
www.dyndns.com)‟s
DNS server. So user has to register user name and hostname to the
website of the DynDNS to use the DDNS function.
4.4.2
TCP/UDP
CSE-H21 sends its IP information to the pre-defined a TCP or UDP server periodically. So user
has to set the server‟s IP address and port number to use this function in advance. CSE-H21
supports both ASCII and BINARY mode.
ASCII message format is followed:
Each byte of the ethernet address is divided by colons, so the total byes of the ethernet address
is 17bytes. The IP address is the CSE-H21‟s IP address that is assigned to the CSE-H21. The
product information is composed by 2 bytes-product ID and 6 bytes-firmware version. For
example: “11010106” means that product ID is 0x11 and the firmware version is 1.1G. The
comments is the [Comments] field in the [OPTION] tab in the ezManager. Each message of the
ASCII data is divided by 0x0d0a.
