    How many ethernet ports does this unit have? The pictures show only ONE per unit (Tx & Rx), but the diagram in the description shows THREE per unit (Tx & Rx), demonstrating simultaneous connections between each unit, as well as a Router, PC, Laptop, etc.
    Tulio Q on Apr 18, 2017
    What is the latency? Is there noticable delay in the audio if the two moniotrs are within earshot of each other?
    Daniel H on Apr 18, 2017
    The product photos show and the diagram are different - the photos show 1 ethernet port on the receiver and transmitter and the diagram shows 3 ethernet ports - which one is it?

    Anything coming out with HDBaseT 2.0?
    Philip K on Apr 18, 2017
    For my application, I am showing live camera video on TVs across the room, but the audio is coming thru a sound system with zero delay. Will this system provide video transmission 100ft away and still sync up with the audio?

    Where can I see the user manual for this?
    New User U on Apr 18, 2017
    BEST ANSWER: Hello, at the moment we do not have the manual available on our website. Feel free to email our technical support team at for further assistance in regards to obtaining the documentation, thank you!
    Can I use Cat-6 Ethernet cable to send 4K video @ 60Hz to a distance of 50ft (15-16 meters)? Or only Cat-7 cable is reliable with 4K @ 60Hz?
    Khurram Z on Apr 18, 2017
    BEST ANSWER: Hi Khurram, the PID 21609 performance features are designed to operate with Cat6 Ethernet cables. while Cat7 cables offer an improvement in performance over Cat6, we have designed this unit to operate with a cable type that is much more common. That said, PID 21609 is capable of supporting 4K@60hz 4:2:0 at 35m with used with an Ethernet Cat6 cable.
    Does it have HDMI CEC or ARC support?
    A shopper on Apr 12, 2017
    BEST ANSWER: It does support CEC pass thru but does not support ARC. Thanks!
    Perhaps a silly question, but would a Cat 5e cable work in any form or fashion, even at a short distance? or is Cat6 the only option?
    Thomas O on Apr 18, 2017
    BEST ANSWER: Hi Thomas, Cat5e will work in some instances, but we highly recommend the use of Cat6 to gain the maximum available performance. Cat6 supports 10-gigabit speeds while cat5e is only capable of gigabit speeds, the discrepancy in cable performance alone is 10x, which can affect the overall performance of the HDbaseT transmission. Cat5e may work in certain special applications, as long as there is an understanding that top level performance may suffer. Thank you for reaching out to us.
    Will this work with other resolutions as well such as 1080i and 720p?
