DIRECTV PI21 パワーインサーター ユーザーマニュアル

1. はじめに

The DIRECTV PI21 Power Inserter is an essential component designed to provide power to DIRECTV Single Wire Multiswitch (SWM) Low Noise Block (LNB) converters. This device ensures proper functionality of your SWM system by delivering the necessary voltage through the coaxial cable, eliminating the need for a separate power supply at the LNB location.

Key features include a frequency range of 2000 kHz to 2150 MHz, minimal signal loss of 2 dB, and compatibility with standard 100-120 V AC input. It features F-type ports for easy integration into your existing satellite setup. The PI21 is compatible with DIRECTV Slim Line Dish Antennas and supports SWM8 and SWM16 multiswitches through a coax connection.

2. 安全情報

2.1重要なお知らせ

This device is designed exclusively for DIRECTV systems. It is NOT compatible with DISH Network or any other cable provider. Attempting to use it with incompatible systems may cause damage to the power inserter or connected equipment.

2.2一般的な安全ガイドライン

• Ensure the power inserter is connected to a grounded electrical outlet.
• ユニットを水や過度の湿気にさらさないでください。
• Avoid placing the unit in areas with extreme temperatures or poor ventilation.
• ユニットを自分で開けたり修理したりしないでください。修理はすべて資格のある専門家に依頼してください。
• Ensure all coaxial cable connections are tight and secure to prevent signal loss or electrical hazards.

3.3 インストール手順

1. Connect to SWM: Connect a coaxial cable from the 'POWER TO SWM' port on the PI21 to the SWM LNB or SWM multiswitch. This connection delivers power to the SWM system.
2. Connect to Receiver (IRD): Connect a coaxial cable from the 'SIGNAL TO IRD' port on the PI21 to your DIRECTV receiver (IRD). This connection carries the satellite signal to your receiver.
3. 電源接続: Plug the attached AC power cord of the PI21 into a standard 100-120V AC electrical outlet.
4. 電源の確認: Check for the indicator light on the PI21 unit to confirm it is receiving power and operating correctly.

The PI21 is suitable for both indoor and outdoor installation with remote power delivery, offering flexible placement options.

3.4 壁面取り付け手順

The PI21 unit can be wall-mounted for secure placement. Follow these steps:

1. Orient the power inserter with the coaxial connectors facing downwards.
2. Place drywall anchors at the desired mounting hole positions on the wall.
3. Mount the power inserter using #8, 1/4-inch slotted hex head screws, 1 inch long, through the flange mounting holes.
4. Tighten the two screws until the power inserter is firmly mounted to the wall.

4. 操作

Once properly connected and powered, the DIRECTV PI21 Power Inserter operates automatically. It continuously supplies the required 21V DC power to the connected SWM LNB or multiswitch, enabling it to function correctly and deliver satellite signals to your DIRECTV receiver(s).

4.1インジケーターライト

The unit features a small LED indicator light, typically located on the top surface. This light illuminates when the power inserter is receiving AC power and is actively supplying DC power to the SWM system. A lit indicator confirms normal operation.

5. メンテナンス

The DIRECTV PI21 Power Inserter is designed for reliable, low-maintenance operation. To ensure its longevity and optimal performance, consider the following:

• クリーニング： Periodically wipe the unit with a soft, dry cloth to remove dust and debris. Do not use liquid cleaners or solvents.
• 接続: Occasionally check all coaxial cable connections to ensure they remain tight and secure. Loose connections can lead to signal degradation.
• 環境： Ensure the unit is not exposed to direct sunlight, extreme heat, or freezing temperatures. While suitable for outdoor installation, protect it from direct weather exposure where possible.
• 換気： 過熱を防ぐために、ユニットの周囲に十分な空気の流れを確保してください。

6。 トラブルシューティング

If you experience issues with your DIRECTV system that you suspect are related to the PI21 Power Inserter, refer to the following troubleshooting steps:

6.1 No Satellite Signal or Intermittent Signal

• 電力を確認します: Verify that the PI21's indicator light is illuminated. If not, ensure the power cord is securely plugged into a working electrical outlet.
• 接続を検査する: Ensure all coaxial cables are tightly connected to the 'POWER TO SWM' and 'SIGNAL TO IRD' ports on the PI21, as well as to the SWM LNB/multiswitch and the DIRECTV receiver.
• 正しいポートの使用法: Confirm that the cable going to the SWM LNB/multiswitch is connected to the 'POWER TO SWM' port, and the cable going to the receiver is connected to the 'SIGNAL TO IRD' port. Incorrect wiring can prevent the system from functioning.
• 電源サイクル: Unplug the PI21 from the electrical outlet, wait 10-15 seconds, and then plug it back in. This can reset the unit.
• システムリセット: If your DIRECTV receiver requires frequent resets, a failing power inserter might be the cause. Consider replacing the unit if other troubleshooting steps fail.

6.2 ユニットの電源が入らない

• アウトレットを確認: 別のデバイスで電源コンセントをテストし、機能することを確認します。
• 電源コード: Ensure the power cord is not damaged and is fully inserted into the unit and the wall outlet.

If troubleshooting steps do not resolve the issue, contact DIRECTV customer support or a qualified technician for further assistance.
