EX-1280CはSerial over ethernetで制御しNode-REDからコマンドを送ります。
やりたいこと
Control Space Designerで作成したGainモジュール（BGM_CD_VOL)についてNode-REDから
- Levelを-60.5dBから12dBに変更すること
- MuteのTru/Falseの制御
- 上記2点のStatusを取得
以上をおこないたい。
Command
上記コマンドより
■Levelの操作とQuery
SA”BGM_CD_VOL”>1=3<CR> : これでBGM_CD_VOLのLevelを3.0dBに変更
GA”BGM_CD_VOL”>1<CR> : これでBGM_CD_VOLのLevelのQueryをかける
GA”BGM_CD_VOL”>1=3<CR> : EX-1280CからLevelについてのレスポンス
■Muteの操作とQuery
SA”BGM_CD_VOL”>2=O<CR> : BGM_CD_VOLのMuteをONにする
SA”BGM_CD_VOL”>2=F<CR> : BGM_CD_VOLのMuteをOFFにする
GA”BGM_CD_VOL”>2<CR> : BGM_CD_VOLのMuteのQueryをかける
GA”BGM_CD_VOL”>2=O<CR>: EX-1280CからMuteについてのレスポンス
これらをNode-REDで実装します。

こちらがLevelを3.0dBにするコマンド
こちらがLevelを取得するQueryコマンドです。
ControlSpaceDesignerを接続状態にしてLevelを10.0にします。
Queryをかけると10.0が取得できました。
Node-REDからLevelを3.0dBにします。
ControlSpaceDesignerのLevelも3.0になりました。
Node-REDからQueryをかけて3.0が取得できました。

まずはControlSpaceDesignerでMuteがFalseのとき、Node-REDからQueryをかけます。
Fと取得できたので、OFF(False）であることがわかりました。
今度はNode-REDからMuteをONにしてみます。
ControlSpaceDesignerのMuteもON(True）になることが確認できました。
まとめ
以上、SAコマンドやGAコマンドを使うことによって、GainノードのLavelを指定して、LevelやMuteをNode-REDから操作する方法を確認できました。
