(4) Parameter error
Parameters in the command block may also be incorrect because parameters are not
separated by a space, exceed the available range, or have an incorrect number of
arguments. When the above error occurs, the sound level meter returns a NAK block
containing the error code 0002H.
(5) Not available in current status
The current status may not work properly in the following cases:
When a request to return octave data in level meter mode or a request to
1
return level meter data in octave mode is received,
When a calibration request is sent while a measurement is still being
2
performed,
When a change of measurement parameters or system parameters is
3
requested while a measurement is being performed.
When the above mentioned error occurs, the sound level meter returns a NAK block
containing the error code 0003H.
5.2.7 Data flow control
The sound level meter has a 3-wire serial interface with a 6-pin P/S2 socket, which
lacks the contact pins for hardware data flow control. The sound level meter does not
support software data flow control. Operation in accordance with the requirements of
section 5.2.9 Nominal Parameters
and received data.
5.2.8 Operation of several devices
Several sound level meters can be connected to the RS-232 interface, thus creating a
measurement network. Users can change the settings of all sound level meters in the
same network by broadcast instructions or access the data and parameters of each
sound level meter by normal commands.
Note the following:
(1) In a network, sound level meters must never have the same ID.
(2) The user may not send a command via broadcast that returns any data.
