Q1：How do I use a Crestron controller to operate
" Play " and " Stop " ?
A 1：Please refer to 10 / P.8 control commands, set
communication settings as 14-3 / P.10 and
start to send command. Recorder / Player
will react instantly upon receiving the
following codes (e.g. ID=00)：
Play \xFA\xAF\x00\x02\x02\xAA\xFF
Stop \xFA\xAF\x00\x03\x03\xAA\xFF
Q 2：When I insert an SD card or a USB flash drive
to SR-101 PRO, how do I query system
status?
A 2：When Recorder / Player detects SD card or a
USB flash drive, basic response will be
initiated automatically. Please refer to 13 /
P.10 for details. System integrators may
decide to execute or ignore the automatic
response (e.g. ID=00).
