                                                               2005/02/14


        This document describes version 2.66 and higher of the 6500 
        software.  Some notes are included describing changes since 
        earlier version but this is by no means a comprehensive list.  
        Due to the number of important changes made in the RS232 
        interface with the release of version 2.66 it is recommended that 
        all 6500s being controlled through the RS232 interface be 
        upgraded to V2.66 or higher. See the file 6500NOTE.DOC for 
        information about previous releases of the RS232 software.

        Not all 6500s are configured with all possible options, it is not 
        in fact possible to install all possible options on a 6500, for 
        example the JIS and ISI options share the same key.  When a 6500 
        receives an RS232 command that requests some feature which is not 
        enabled it responds as if it did not understand the command by 
        returning an ACK packet and setting the error flag.  We recommend 
        you check what options are installed on a 6500 with the "Get 
        Version" command rather than check the error code at each 
        command.

        The RS232 command set recognized by the 6500 can be divided into 
        two categories, the first set contains those commands recognized 
        at any time the 6500 issues polls, the other set changes 
        depending on what operating mode the 6500 is in.

        Commands marked with * are dynamic data get commands. The data 
        returned by these commands may not be valid the first time you 
        read the data after changing the operating state of the 6500. You 
        should read the data from the 6500 twice to insure that the data 
        is valid.

        Commands marked with ** are get curve commands. In composite 
        mode, real time curves are dynamic, and the data may not be valid 
        after changing the state of the instrument. 

        For more information on reading dynamic data and other 
        information on programming the 6500, see the 6500NOTE.TXT file.
        Except where noted (see 6500NOTE.TXT) the 6500 does not support 
        the Expanded command formats.

        The common commands that are always recognized are:

        Command          -- Common ---                   Notes    Number
        ----------------------------------------------------------------
        Set Keyboard Control ..............................2......... 62

        Get Keycode ................................................. 58
        Get Instrument State ..............................2......... 60
        Get Keyboard Control ..............................2......... 63

        Get Printer Selection .............................8......... 93

        Do Reset .................................................... 38
        Do Error ..........................................2......... 67

        The remaining commands are divided according to what operating 
        mode the 6500 is in what the command is issued.

        Note: Commands 28 and 33 are always supported on all instruments 
        that follow the FIPP protocol. Generally, command 38 is supported 
        on all instruments that support the FIPP protocol, but the 
        effects of the command may be different.

        # Commands 81,82,83,84,90 and 91 are not available as common   
        commands in all instruments. It is recommended that you limit   
        the use to the test state where the command is appropriate.

        Be sure to check the other instrument command files to determine 
        which commands are common, and the instrument note file to 
        determine any differences between instruments for a command, as 
        well as any version related issues that might be important if you 
        intend to write a program that supports multiple instruments.
