UDP Communication Parameters

You should configure the udp object to match your instrument's communication configuration, which you typically set with its front panel.

• RemoteHost
• RemotePort
• LocalHost
• LocalPort
• LocalPortMode
• Terminator

RemoteHost

Specify the remote host IP address or name that the udp object will connect to.

RemotePort

Specify the remote port that the udp object will connect to.

LocalHost

Specify the local host IP address or name that the udp object will connect from. If you specify LocalHost as empty the system's default will be used.

LocalPort

Specify the local port that the udp object will connect from. If LocalPortMode is auto, the port used will be determined by the system.

LocalPortMode

Select the mode used to determine the LocalPort that the object will use.

• auto - The object uses a free local port determined by the system.
• manual - The value specified in LocalPort is used.

Terminator

Select the character(s) used to terminate commands written to or read from the instrument. You can configure Terminator to an integer value ranging from 0 to 127, to the equivalent ASCII character, or to empty (''). Some common terminators include:

• 'CR' or 13 - A carriage return is used.
• 'LF' or 10 - A line feed is used.
• 'CR/LF' - A carriage return followed by a line feed is used.
• 'LF/CR' - A line feed followed by a carriage return is used.

Additionally, you can set Terminator to a 1-by-2 cell array. The first element of the cell is the read terminator and the second element of the cell array is the write terminator.

When performing a formatted write operation, all occurrences of \n are replaced with the terminator. When performing a formatted read operation, one of the ways the operation completes is when the terminator is read. You can also use the terminator to generate a bytes-available event when the BytesAvailableFcnMode parameter is set to terminator.
