産業用SIPインターコムのアンプオーディオ出力を制御する方法は?

はじめに

概要

産業用デバイスが外部アンプに接続されている場合、アプリケーションシナリオに基づいて、アンプにオーディオを出力するかどうかを制御できます。 通常の通話中はアンプをOFFにし、内蔵スピーカーのみを使用します。放送や緊急アナウンス中はアンプを起動する必要があります。 このドキュメントでは、デバイスのモデルに応じた2つの制御方法について説明します。

対応モデル

BHP‑SOS10, BHP‑SOS10V, BHP‑SOS10D, BHP‑SOS11V, BHP‑SOS11V2, BHP‑SOS16, BHP‑SOS16V, BK‑ROIP‑PA2, BK‑ROIP‑PA2S, BK‑ROIP‑PA3, BHP‑SOS12.

事前準備ツール

① 対応デバイス1台(例:BHP‑SOS16V)、PoEスイッチ1台(またはDC電源)、アンプ1台、スピーカー1台。アンプをデバイスに、スピーカーをアンプに接続します。デバイスをスイッチに接続します。
② 同じスイッチに接続されたデバッグ用コンピュータ1台。ネットワーク接続を確保します。

アンプのオーディオ出力を制御する

アンプ出力は、Audio Outインターフェースを有効にするか、リレーを使用してアンプの電源を切り替えることで制御できます。両方の方法を以下に説明します。

Audio Outインターフェースによる制御

この方法は以下に適用:BHP‑SOS10シリーズ、BHP‑SOS11シリーズ、BHP‑SOS16シリーズ、BK‑ROIP‑PA2、PA2S、PA3。 注:BK‑ROIP‑PA2/PA2SはHeadsetインターフェースを使用し、PA3はLine Outを使用します。i10/i11シリーズはカスタム2ピンMX1.25配線が必要です。 Web UIで設定: (1) Web UIにログイン(デフォルトのユーザー名/パスワード:admin)。
(2) インターホン設定メディア設定メディア設定に移動します。

  • 外部スピーカーを有効にするハンズフリー&ライン出力に設定します。

  • ライン出力トリガーステータスインターホン着信先に設定します。

パラメータの説明:

  • ハンズフリー&ライン出力:ハンズフリーオーディオとライン出力オーディオの両方を有効にします。

  • ライン出力トリガーステータス

    • 呼び出し中:呼び出し中にトリガー

    • 発信者(通話中):発信時にトリガー

    • SIP着信先(通話中):SIP着信時にトリガー

    • マルチキャスト着信先:マルチキャスト受信時にトリガー

    • インターホン着信先:インターホン着信時にトリガー
