Using Telnet

In an MS-DOS Command Prompt box type: telnet hostname 5024 where hostname is the RPS
hostname or IP address, and 5024 is the instrument's telnet port.
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

Power supplies allow any combination of up to six simultaneous data socket,
control socket, and telnet connections to be made.
Keysight 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 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:
After the 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, and all query responses
returned on the control socket will 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.
Service requests are enabled for control sockets using the Service Request Enable register. Once
service requests have been enabled, the client program listens on the control connection. When SRQ
goes true the instrument will send the string "SRQ +nn" to the client. The "nn" is the status byte value,
which the client can use to determine the source of the service request.

Interface Lockout

The USB interface, LAN interface, and the Web server are enabled when shipped. To enable or disable
the interfaces from the front panel:
Front Panel Menu Reference
Select System\Admin\IO
Enable or disable the interfaces by checking or unchecking the
following items:
Enable LAN, Enable GPIB, and Enable USB
If you cannot access the Admin menu, it may be password protected.
