8.2.2 Firmware version
The number followed by the result code 235 is a version number of the ARL2300. The number
only represents major change in the firmware.

UDP audio transmission port
To receive UDP data (audio data) from remote ARL2300, the client PC needs to send the "p"
command as described in chapter 7.2.1.
Selects the LPF in the ARL2300. The cut-off frequency and
parameter as follows:
f0: Through, f1: 9kHz, f2: 6.4kHz, f3: 3.2kHz
Selects the audio gain of the ARL2300. The audio gain and
parameter as follows:
g0: 0dB, g1: +3dB, g2: +6dB, g3: -6dB
Adds the LM value (S meter value) to UDP data.
Example: l0: No LM vale is added , l1: LM value is added
This command is required to start audio transmission from the
ARL2300. Please see details in chapter 8.3.
Stop audio transmission from the ARL2300.
Selects the sampling rate (audio quality). This command
should be used with the "f" command. Available sampling
rates and parameters as follows:
s8000: 8kHz, s11025: 11.025kHz, s16000: 16kHz,
s22050: 22.05kHz, s32000: 32kHz, s44100: 44.1kHz,
s48000: 48kHz
Adds the time-stamp to UDP packet. The time-stamp format
is a value in seconds started from Jan 1, 1970. (aka Unix time)
Example: t0: No time stamp is added. t1: Time stamp is
added.
