ing the encoder directly, the sender (automation system) sends
data to the IP forwarding provider, which automatically keeps
track of encoder’s changing IP address and sends the data to
the encoder’s current IP address.
Dynamic DNS
Providers
There are three popular forwarding services available over the
Internet. These services require registration on the appropriate
Website and, as of this writing, are free of charge.
Click:
Tools/DynDNS
to bring up
the
Dynamic DNS Config
window
shown here. The particular for-
warding provider is selected by
clicking on the name. This may
also be selected locally with the
front-panel jog wheel, as de-
scribed under Menu 54 (Page 21),
or even assigned using the Ter-
minal utility with a
DYNDNS=
command.
A Hostname, Username and Password specific to your 730 En-
coder will be determined when you sign up on the provider’s
Website. This information may then be entered into the soft-
ware window, set locally with the jog wheel under Menus 55, 56
and 57, or may be entered using the Terminal utility.
Dynamic DNS
System Abuse
Each IP address renewal utilizes some small part of the for-
warding provider’s processing resources. These providers
don’t take well to repeated and unnecessary IP address renew-
als. The 730 encoder will normally advise the provider only
when the IP address changes, but it also must sign on following
a power interruption and whenever the
DynDNS Mode
is
changed. If a particular account makes a nuisance of itself, the
provider may justifiably terminate the account. If this happens
the front-panel display will show an appropriate status mes-
sage in Menu 54 as explained below.
Status Messages
The Menu 54 window shows not only which dynamic DNS pro-
vider has been selected, but also displays a message number
and ‘short label’ for a variety of conditions relating to the dy-
namic DNS service. A chart of these messages and their expla-
nations is given here.
Message ID
