compatible computer), use a crossover cable.
Overview of Commands
Commands are each formatted as an ASCII code string composed of “stx” plus “three alphabetic letters (capitals)” plus “;” (semicolon).
The three letters of the alphabet indicate the type of command.
If the command has an argument, a colon (“:”) is inserted between the command letters and the argument. When multiple arguments occur, they are
separated by commas (“,”).
stx An ASCII-code signal name (code number: 02H), this is a control code indicating the start of a command.“H” indicates that it is a
hexadecimal value.
:This is the code that the VR-4HD recognizes as a separator between a command and its argument.
;This is the code that the VR-4HD recognizes as the end of a command.
* The codes of stx (02H), ACK (06H), and Xon (11H)/ Xo (13H) are the control codes.
* When successively sending commands to the VR-4HD from an external device, after each command, be sure that“ACK” is returned before sending the
next command.
