Operating the Power Supply Remotely 4
Using Telnet
In an
You should get a Telnet session box with a title indicating that you are connected to the power supply. Type the SCPI commands at the prompt.
Using Sockets
Agilent instruments have standardized on using port 5025 for SCPI socket services. A data socket on this port can be used to send and receive ASCII/SCPI commands, queries, and query responses. All commands must be terminated with a newline for the message to be parsed. All query responses will also be terminated with a newline. The power supply allows any combination of up to three simultaneous data socket and telnet connections to be made.
The socket programming interface also allows a control socket connection. The control socket can be used by a client to send device clear and to receive service requests. Unlike the data socket, which uses a fixed port number, the port number for a control socket varies and must be obtained by sending the following SCPI query to the data socket: SYSTem:COMMunicate:TCPip:CONTrol?
After the control port number is obtained, a control socket connection can be opened. As with the data socket, all commands to the control socket must be terminated with a newline. All query responses will also be terminated with a newline.
To send a device clear, send the string “DCL” to the control socket. When the power supply has finished performing the device clear it echoes the string “DCL” back to the control socket.
