USB output (digital data output at any time) Detailed description
1. How to set (in Menu <System> (1/3))
OFF ：USB out(digital data output) OFF
Lp ：Instantaneous values are output every second.
LpB ：When using the octave filter, the level numerical data of each band is outputted
every 8msec.
Necessary the 1/1 and 1/3-octave Real-time Analysis Card(NA-0038)
Wave ：A/D values are outputted every 48kHz
2. Using interface
1) USB ： IC chip (FT245)
2) Transfer speed ： 9600～921600bps
3) Data length ： 8bit
4) Stop bit ： 1bit
5) Parity check ： none
3. Output details
3-1 Lp(Instantaneous values every second)
1) Required baud rate： 9600bps
2) Data Contents ： 5Byte+CR ＜ex. 43.0dB→20 34 33 2E 30 0D (43.0+CR)＞
3-2 LpB(Level value for every 8msec in each band)
1) Required baud rate： 460800bps or 921600bps
2) Data Contents ： Case of 1/3 -octave
130.0+CR+LF ←12.5Hz
130.0+CR+LF ←16Hz
・ Total 34 data
・
130.0+CR+LF ←All pass
130.0+CR+LF ←Over all
+CR+LF ←Brake code
130.0+CR+LF ←Next data（12.5Hz）
3-3 Wave（16Bit binaryA/D waveform data）
1) Required baud rate ： 921600bps
2) Data Contents ： Continuous output of waveform every 48kHz（20.8us）
0000～FFFF （0000→Negative max,8000/7FFF→center, FFFF→Positive max）
<System> 1/3
Mode ：Normal
Data delete：off
LCD cont ：*****
Date y/m/d ：00/00/00
Time h/m/s ：00:00:00
Printer(PC)set：9600
USB out ：OFF
OFF → Lp → LpB → Wave → OFF
※
Output value is started/stopped at the same time as measurement by
［Start/Stop］key input.
It is output at any time regardless of Interval and MeasTime.
