    There is no feed-back from the controlled device. This means that if the controlled device is not powered on, or is not even attached, or is sent an incorrect string, the VM700T function or program will continue executing.

    In this case, function execution stops until you type a carriage return. If the Remote Control/Message Display item in the Communication Setup file is set to VM700 Screen, the message appears on the display screen of the VM700T even when the function is being played back from remote control. Function execution stops until you touch the display screen.

    Notice that in this example some of the results data arrived in the middle of the VM700T prompt string, making the VM700T output appear garbled. In order to separate the two data streams, you must know how they were combined.

  • Page 66: Simple Remote Control

    Protocol, or SLIP, mode establishes an error-free connection between the VM700T and the PC, through the use of data checking and re-transmission techniques. When the VM700T is in SLIP mode, it lets you write files into its non-volatile memory, by means of programs such as FTP (File Transfer Protocol, for which implementations exist on many platforms, including PC’s).
  • Page 67 PC-NFS, and WIN/PC. If you only need to send commands and receive data from the VM700T and do not need to send files into it, you should consider using Tektronix’ VMT program. This program is made to communicate with the VM700T. It incorpo- rates more knowledge of the VM700T than a general-purpose terminal emulator can, and makes the task of remote control of the VM700T considerably easier.

  • Page 68: Starting A Terminal Session

    Before you start a terminal session with the VM700T, you should check several things: 1. Verify that a serial port on the PC and a serial port on the VM700T are connected via an RS-232-C cable. 2. Verify that the correct drivers are loaded on the PC, if you intend to use SLIP mode.

  • Page 69: Executing Measurements

  • Page 70 “snapshot” of the application’s measurements and stores them in a file in the Measurement Results directory. When the results are written in the file, the VM700T sends a message out the control port, consisting of the filename in which the results were stored. This is always the same as the application name.

This example puts the VM700T into Auto mode, measures the PAL Bar Amplitude Error, 2T Pulse K-Factor, and Sync Amplitude Error for the current channel, then writes the results into a file named Auto in the Measurement Results directory.

  • Page 72: Printing Files

    Then, the print spooler sends it out to the Copy port. The VM700T prompts for a new command as soon as the file is submitted to the spooler; the file need not have actually printed out yet.

  • Page 73: Reading/Setting Configuration Parameters

    The VM700T reads several files when it is powered up. The Source_Selection Video file specifies a file from the Video_Source Files directory, one for each channel. VM700T units equipped with both Option 01 and Option 11 specify a file from the Video_Source Files directory for each channel and for each standard (NTSC and PAL).

  • Page 74: Configuration Keywords

    All these files are stored in the nonvolatile memory of the VM700T. At start-up time, the files are read into random-access memory, where they are referenced as needed when the instrument makes measurements or performs other operations.

  • Page 75: Getting Configuration Parameters

    “read-only” parameters in Appendix A: Get/Set Keywords. Getting Configuration You find out the current value of any VM700T configuration parameter by using Parameters command and the parameter of the keyword. The syntax of the command is as follows: Not all keywords require a channel specification.

  • Page 76: Restoring Configuration Parameters

    Restoring Configuration command re-reads all configuration values from the Parameters configuration files. Note that when you record a function, the VM700T puts many commands at the start of the function file, and puts a command at the end. These commands make it possible to reproduce the exact state in which a VM700T function was recorded when the function is played back.

  • Page 78: Starting Ftp

    There are commands available to send and receive files, to change the server’s working directory, to get directory listings, to create new directories, and to remove directories and files. 4–13 VM700T RS-232 Interface Programmer Manual...

  • Page 79: Using Ftp

    Simple Remote Control The VM700T implements the FTP protocol in such a way that it can act as an FTP server, while a computer connected to it can act as an FTP client. In order to use FTP to access the file system of the VM700T, you must have an FTP client program running on the computer connected to the VM700T.
  • Page 80 When you try to write a configuration file, the file is compared against an internal template to ensure that it will be readable when needed by the VM700T. If this check fails, an error is returned, and the file is not written. To ensure the proper file format, it is a good idea to first read a valid matching configuration file from the VM700T, modify it locally, then write it back.
  • Page 81 Simple Remote Control command lists the files in the current VM700T directory. Example: command is similar to , but also returns the size (in bytes) of each directory entry. Entries with a size of 0 are most likely (but are not necessarily) directories.

  • Page 82: Computer-Based Remote Control

    There are several reasons you may wish to write a program to control the VM700T instead of controlling it from a terminal or using its front panel. These are the following: a greater degree of automatic operation. Repetitive operations are more efficient and less prone to error when executed from a program than manually.

  • Page 83: Programming Languages

    Computer-Based Remote Control Programming Languages Before you start to write programs to control the VM700T, you have to decide what language to write the program in. You can write programs to control the VM700T in any programming language you like. However, you will probably want to use a language for which libraries of routines are available to handle data communications.

  • Page 84: Communicating With The Vm700T

    Computer-Based Remote Control Communicating with the VM700T Before you can write programs to control the VM700T, you must know how the VM700T communicates with a computer and understand the following: terminal versus computer mode (such as local versus remote echo) VM700T responses that indicate: acceptance of a command;...
