4. คู่มือการติดตั้ง

Follow these steps for a successful setup:

1. เชื่อมต่อตัวส่งสัญญาณ (TX):
   • Connect one end of an HDMI cable to the HDMI output of your source device (e.g., laptop, STB, PC).
   • เชื่อมต่อปลายอีกด้านหนึ่งของสาย HDMI เข้ากับ อินพุต HDMI port on the Transmitter (TX) unit.
   • If you wish to use the HDMI loop-out function, connect another HDMI cable from the HDMI Output (Loop-Out) port on the TX unit to a local display.
   • Connect the IR transmission cable to the IR Signal Transmission port on the TX unit. Position the IR emitter head near the IR receiver window of your source device.
   • เชื่อมต่ออะแดปเตอร์เพาเวอร์เข้ากับ พลังใน port of the TX unit and plug it into a power outlet.
2. เชื่อมต่อตัวรับสัญญาณ (RX):
   • เชื่อมต่อปลายด้านหนึ่งของสาย HDMI เข้ากับ เอาท์พุต HDMI พอร์ตบนตัวเครื่องรับสัญญาณ (RX)
   • Connect the other end of the HDMI cable to the HDMI input port of your remote display (e.g., TV, projector).
   • Connect the IR receiving cable to the IR Signal Reception port on the RX unit. Position the IR receiver head in a location where it can easily receive signals from your remote control.
   • เชื่อมต่ออะแดปเตอร์เพาเวอร์เข้ากับ พลังใน port of the RX unit and plug it into a power outlet.
3. เปิดเครื่องและจับคู่:
   • Turn on both the Transmitter (TX) and Receiver (RX) units using their respective power switches.
   • The units will automatically attempt to pair. This process typically takes about 18-22 seconds. The WiFi Indicator (W) will flash during communication.
   • Once successfully paired, the video and audio from your source device will be displayed on the remote screen.

5.1. ฟังก์ชัน HDMI Loop-Out

The Transmitter (TX) unit is equipped with an HDMI loop-out port, allowing you to connect an additional display at the source location. This means you can view the content on two screens simultaneously: one connected directly to the TX unit via loop-out, and another wirelessly connected to the RX unit.

5.2. IR Remote Extender Function

The IR remote extender allows you to control your source device (e.g., STB) from the remote location where the Receiver (RX) unit is located. This eliminates the need to be in the same room as your source device to change channels or navigate menus.

• Ensure both IR cables are properly connected to their respective units (TX for transmission, RX for reception).
• Point your remote control at the IR receiving cable connected to the RX unit. The signal will be transmitted wirelessly back to the TX unit, which then relays it to your source device.
• Note: This function is not compatible with Bluetooth remotes.
• If the IR remote control function does not work, you can try pressing the IR-Switch button on the Receiver (RX) unit to cycle through different IR frequencies (30KHz, 38KHz, 47KHz, 56KHz) to find one compatible with your remote control.

5.3. One Transmitter to Four Receivers (1 TX to 4 RXs)

The PAKITE Wireless HDMI system supports connecting one Transmitter (TX) unit to up to four Receiver (RX) units simultaneously. This allows you to duplicate or extend your screen to multiple displays in different rooms, sharing content from a single source.

• To add additional receivers, simply power them on and ensure they are within the signal range of the transmitter. They will automatically connect.
• Important: The system does not support the use of multiple transmitters in the same environment to avoid signal interference.

6 การแก้ไขปัญหา

หากคุณพบปัญหา โปรดดูปัญหาทั่วไปและวิธีแก้ไขต่อไปนี้:

• ไม่มีสัญญาณ / หน้าจอดำ:
  • Ensure both TX and RX units are powered on and their power indicators are lit.
  • Check all HDMI cable connections. Ensure they are securely plugged into the correct ports.
  • Verify that your source device is outputting a signal and is set to a progressive scan resolution (e.g., 1080P). Interlaced resolutions (e.g., 1080i) are not supported.
  • Confirm that the input source on your display (TV/projector) is set to the correct HDMI port connected to the RX unit.
  • Try resetting both the TX and RX units by pressing and holding the Reset Button for 5 seconds.
• Intermittent Signal / Poor Quality:
  • Ensure the TX and RX units are within the recommended transmission range (up to 200m in open areas, 50m through walls).
  • Minimize obstacles between the TX and RX units, especially thick walls or metal objects, which can interfere with the wireless signal.
  • Check for potential interference from other wireless devices operating on 2.4GHz or 5.8GHz frequencies.
• รีโมทคอนโทรลอินฟราเรดใช้งานไม่ได้:
  • Ensure the IR transmission and reception cables are correctly connected and positioned. The IR emitter should be directly facing the source device's IR receiver.
  • กดปุ่ม IR-Switch button on the Receiver (RX) unit to cycle through different IR frequencies (30KHz, 38KHz, 47KHz, 56KHz) to find one compatible with your remote control.
  • Confirm your remote control is not a Bluetooth remote, as these are not supported.
