configureTerminator

Set terminator for ASCII string communication with VISA resource

Since R2021a

    Syntax

    configureTerminator(v,terminator)
    configureTerminator(v,readterminator,writeterminator)

    Description

    configureTerminator(v,terminator) defines the terminator for both read and write communications with the VISA resource v. Allowed terminator values are "LF" (default), "CR", "CR/LF", and integer values from 0 to 255. The syntax sets the Terminator property of v.

    After you set the terminator, use writeline and readline to write and read ASCII-terminated string data.

    example

    configureTerminator(v,readterminator,writeterminator) defines separate terminators for read and write communications.

    example

    Examples

    Create a connection to a VISA resource. This example shows a connection to a device with the alias COM4 using the VISA-Serial interface.

    v = visadev("COM4");

    Set both the read and write terminators to "CR/LF".

    configureTerminator(v,"CR/LF")

    Confirm the change.

    v.Terminator
    ans = 
"CR/LF"

    Create a connection to a VISA resource. This example shows a connection to a device with the alias COM4 using the VISA-Serial interface.

    v = visadev("COM4");

    Set the read terminator to "CR" and the write terminator to 10.

    configureTerminator(v,"CR",10)

    Confirm the change.

    v.Terminator
    ans=1×2 cell array
    {["CR"]}    {[10]}

    The first element in the array is the read terminator and the second is the write terminator.

    Input Arguments

    collapse all

    VISA resource, specified as a visadev object.

    Example: configureTerminator(v,"CR/LF") sets the terminator value for the VISA resource v.

    ASCII terminator for read and write communication, specified as "LF", "CR", "CR/LF", or a numeric integer value from 0 to 255. Use this form when setting the same terminator for both read and write. When reading from the remote host with a terminator value of "CR/LF", the read terminates on an occurrence of CR and LF together. When writing to the remote host with a terminator value of "CR/LF", the write terminates by adding both CR and LF. This input argument sets the Terminator property.

    Example: configureTerminator(v,"CR/LF") sets both the read and write terminators to "CR/LF".

    Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | char | string

    ASCII terminators for read or write communication, specified as "LF", "CR", "CR/LF", or a numeric integer value from 0 to 255. Use this form when setting different terminators for read and write. When reading from the remote host with a terminator value of "CR/LF", the read terminates on an occurrence of CR and LF together. When writing to the remote host with a terminator value of "CR/LF", the write terminates by adding both CR and LF. This input argument sets the Terminator property.

    Example: configureTerminator(v,"CR",10) sets the read terminator to "CR" and write terminator to 10.

    Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | char | string
