5.7.8.7 Using UDP Sockets
This is a simpler socket type with reduced network traffic. It is a ‘connectionless’ protocol because
messages are sent and there is no acknowledgement that they have been received.
Open UDP socket port 8005 to send SCPI commands.
Responses to queries are sent back automatically with a line-feed terminator and carriage return
appended.
Before opening a UDP socket, it is required to open the web page and set the controller access to
Multiple Clients.
5.7.9 Connecting Over WAN
To connect over the Wide Area Network (i.e.: the global internet), the following settings must be
made in the network server.
5.7.9.1 View Web Pages Over WAN
The
Power Supply LAN interface has a server for running the web pages. The web server
is listening in Port 80.
The network administrator must obtain and assign a Global IP for the Power Supply. On the
network server, the network administrator also must ensure port 80 is exposed to WAN
connectivity.
5.7.9.2 Use Sockets Over WAN
The network administrator must obtain and assign a Global IP for the Power Supply. On the
network server, the network administrator also must ensure port 8003 (for TCP sockets) or port
8005 (for UDP sockets) is exposed to WAN connectivity.
