6 Client Commands and Console Responses
6.1 VR - Query Version
The version command requests the Software version of the Console. Note the Console must not
be in Low Power Mode (see section 5.5 Low Power Mode) to get a valid response. Otherwise an
Error packet will be sent. Use the SysRdy command to query the Low Power State of the system.
(See 6.11 SysRdy - Query System Ready.)
