Server
The server can be defined by its IP address, or its domain name. This server can reside on the local
network, or on the internet. Once the instrument is connected to the access point, it will attempt to
contact the IP address or domain name of the server. A domain name is often used in conjunction with
a DDNS service. This allows the IP address of the server to change over time, without affecting the
connection.
Note:
When the server is not on the local network, the configuration of the router it is connected to is
more complicated. See section 8.7.4.
8.7.3 Manual Connection
In order to test the WiFi™ connection, after setting up the Router or Access-Point and/or the server's IP
address or domain name, but prior to setting a connection schedule, press the Connect-Now button.
The connection status will show that the instrument is immediately trying to connect, and will show all
the connection stages in sequence.
In order for the last stage (Server Connected) to be reached the server must be working, must be
reachable, and must be running the Instrument_Listener application.
8.7.4 Setting Up the Server to Work in a Local or Wide Area Network.
Setting up a server to run on the same local network the instrument is in is relatively easy. In addition to
the steps above, one should make sure of the following:
•
If the server is contacted by its IP address, the IP address of the PC working as a server must
be fixed. To that end, the router that the PC is connected to must be set to use "Static DHCP"
for that PC. This way the IP address will not change over time.
•
The PC working as a server must be always on, and must be running the Instrument_Listener.
Otherwise the connection can't be established when the instrument tries to connect.
Setting up a server to work in a Wide Area Network (in a different city for instance) is a little more
complicated. One option is to use a corporate server running the Instrument_Listener. In that case it
usually makes sense to use a domain name to represent the server's address.
When the server is a simple PC in an office, the following configuration may be used:
•
The router that the PC is connected to is configured for "Port Forwarding". Port Forwarding
must be enabled on port 50 000, for TCP/IP, to the local IP address of the PC.
•
Static DHCP must be configured on that PC, so its local IP address will not change.
•
Ideally the router must be setup to use a DDNS service, such as noip.com. This way the
instrument can use a domain name registered through the DDNS service in order to contact
