未使用 美品 レガシー KSW-SZ3 3回線高信頼性縦型手動切替器

関西通信電線株式会社(KANSAI)製の「3回路双方向全ピン切替器 KSW-SZ3」です。
未使用の美品です。
古いパソコンや周辺機器で使われていた「RS-232C(シリアル)」規格の信号を、1台の機器に対して3つの接続先から手動で切り替えて使うための装置です。
3回路対応: A・B・Cの3つの接続先を前面のダイヤルで切り替えられます。
全ピン切替: D-Sub 25ピンのすべての信号線をストレートに切り替える仕様です。
双方向対応: 1台のPCで3台の機器を使い分けることも、逆に3台のPCで1台の機器を共有することも可能です。
詳細は箱裏写真をご参照ください。

レガシーデバイス設備を維持している工場や研究機関などでの需要はあるかもしれません。
また外箱、マニュアル、ケーブル、保証書が揃っており、本体も非常に綺麗な状態で、これだけ付属品が揃っている完品は珍しいため、コレクターや保守部品を探している方には価値があるかもしれません。

- ブランド: 関西電気株式会社
- モデル名: KSW-SZ3
- タイプ: 3チャンネルセレクター
- ポート数: 3ポート
- 付属品: ケーブル付

少なくとも私は一度も使用した事はなく今回初めて撮影のため外箱を開封しましたが機器の状況を見ると未使用のようです。
付属のケーブルについては未開封です。

【注意‼︎】以下ご確認ください。
20年くらい前に新古で購入した物です。
当時PCを際限なく増やしていたため役立つ事もあるだろうと購入したもののそのまま倉庫に眠らせていました。
未使用のため動作確認はしていません。
経年のためゴム足基部に黄ばみが出ています。
箱込みの重量は1.75kgと割と重いです。
外箱とユーザーズマニュアルには傷みがあります。
以上納得された方のみご購入ください。
即決OKです。
