This HDBaseT™ repeater lets you add another HDMI® display to your existing ST121HDBTE or ST121HDBTPW HDBaseT extender kit. This makes it easy to expand your digital signage system to meet the growing needs of your business.

The repeater receives the HDBaseT signal from your transmitter and deploys it to the receiver up to 70 m away while outputting the HDBaseT signal to an HDMI display at the repeater's location. The repeater also enables you to add an HDMI source at the repeater’s location and switch between sources at each of your connected HDMI or HDBaseT displays.

Add affordable scalability to your ST121HDBTE or ST121HDBTPW HDBaseT extender kit

The repeater connects between your existing HDBaseT transmitter and receiver, enabling you to connect an HDMI display to the repeater, then daisy-chain the HDBaseT signal to an additional location up to 230 ft. (70 m) away. The repeater also features an HDMI input that lets you connect a different HDMI video source at the repeater and then switch between which source is output to the receiver.

For additional flexibility, you can add up to three HDBaseT repeaters to an ST121HDBTE or ST121HDBTPW extender kit. Using multiple repeaters (sold separately)  you can run an HDBaseT signal to a total of four locations, which provides the ideal solution for routing digital signage through large buildings such as shopping centers, stadiums, schools, or hospitals.

Ensure professional installation and operation

The HDBaseT repeater includes hardware for mounting it out of sight on a wall or in an equipment rack. This helps to reduce clutter and ensures a professional installation that doesn't draw your viewers' attention away from the content on your display -- perfect for customer facing displays in bars or restaurants.

Get astonishing 4K picture quality from an impressive distance

With the A/V industry quickly adopting 4K as the new high-resolution video standard, long-range video distribution can be difficult, given the distance limitations of standard HDMI cables. With support for 4K, you’ll be amazed at how HDBaseT maintains your Ultra HD picture quality -- four times the resolution of high-definition 1080p, even at 130 feet away from your video source.

Maintain support with HD equipment

Because the extender is backward compatible with High-Definition 1080p and lower resolutions at 230 feet away, you can comfortably use this extender to make any video source look great, while future-proofing your setup for 4K implementation.

What is HDBaseT?

HDBaseT is a standardized, zero-latency, video distribution technology that’s revolutionizing HDMI distribution. HDBaseT uses an advanced method of modulation that enables you to distribute uncompressed HDMI audio and video along with additional signals, over a single Ethernet cable. Offering greater versatility than traditional HDMI extenders and longer distances than HDMI cables alone, HDBaseT is the clear choice for every integrator and system designer, because it can do so much, with just a single cable.

The ST121HDBTRP is backed by a 2-year StarTech.com warranty and free lifetime technical support.

Applications

Frequently Asked Questions

Installation

There are a few things you'll want to take care of before you deploy your new video extender in your setup.

It’s important to make sure you have everything you will need ahead of time. These items are listed below.

  • Transmitter
  • Receiver
  • Video source
  • Display
  • Video cables
  • (Optional) Ethernet or fiber cables
  • (Optional) Power adapter(s)

It’s also important to test everything in a simplified setup ahead of time to make sure everything works and that you understand how it works. 

In order to set up your video extender, complete the following:

  1. Position your video transmitter near your video source.
  2. Connect the video output from your video source to the video transmitter.
  3. (Optional) Connect the power adapter to the video transmitter.

Note: Not all video extenders require external power, or require external power on both ends.  Refer to the manual for more information.

  1. Position your video receiver near your display.
  2. Connect the video output from your video receiver to your display.
  3. (Optional) Connect the power adapter to the video receiver.
  4. If using a wired video extender, connect your network cabling between the video transmitter and the video receiver.
  5. (Optional) If you are extending anything else supported by your video extender connect those devices to the transmitter and receiver.
  6. (Optional) If you are using a wireless extender, there may be a sync button you need to press to pair the transmitter and receiver.

Now that you have set up your video extender, you can check that everything is working.  You should be able to see your video source's output on the display connected to the video receiver.

If at this point you have further questions regarding a Startech.com video extender, contact our technical support team for further assistance. 

To get the highest quality signal from your source to your display when you use an HDMI extender, do the following:

  • Make sure that the HDMI versions of the source, extender, and destination are compatible. For example, if you require 3D support, make sure that all of the devices can support 3D over HDMI.

  • Use the least amount of adapters, splitters, or converters as possible. Each device that you use in your setup creates additional points of potential failure and creates more steps for an HDCP key to hop through, which may cause issues with older displays. For more information on HDCP, refer to the following FAQ: http://www.startech.com/faq/video_signal_converters_HDCP.

  • Use an HDMI extender that exceeds the requirements of the setup. For example, if you need to extend the signal 200 feet, it is best to use an extender capable of more than 200 feet.

  • Make sure that all of the CAT 5/6 runs are as straight as possible, with the least amount of coiling.

  • Make sure that all of the patches, wall jacks, and cables use the highest possible CAT specification, (for example, CAT 6), and were tested to conform to the standard.

  • Use patches, wall jacks, and cables with the same pin configuration. For more information on T568A versus T568B wiring, refer to the following FAQ: http://www.startech.com/faq/network_cables_a_vs_b_pinout.

  • Keep the cabling away from sources of high noise.

  • Make sure that you use adequate electrical grounding in your setup.

Troubleshooting

  1. The power adapter may not be connected at the correct unit or may not be connected at all.  Please check your product manual to see where your power adapter has to be positioned.
  2. An adapter to another video signal may be connected to the Transmitter or Receiver unit.  Please avoid any converters for the initial setup.
  3. The Cat 5 or 6 cable coming from the transmitter or receiver unit may be connected to a network switch.  Some of our video extenders will work in this configuration, but others will not. Please check your product manual to see if your model can be used connected to an IP network. For the initial setup, avoid connecting the Cat 5 or 6 cables to any network switch, hub, or router.
  4. The category of Unshielded Twisted Pair (UTP) cables may not meet StarTech.com’s requirements. Ensure at least Cat 5, 5e, or six cables are used, and they have eight wires. Some Cat 5 cables only have four wires. If using Cat 6 cables, be aware they have more twists per foot, so you may have to use shorter cable lengths if using Cat 6 cabling between your video extenders.
  5. Bundling up the UTP cabling connected to the extenders can cause crosstalk, which will prevent the video signal from showing on the display.  Unwrapping the cable should resolve this issue.
  1. Please check to see if your model has an adjustable Gain dial on the remote unit.
  2. If it does, use it to adjust the color until it is acceptable.
  3. Replace the VGA cable with a higher quality cable like StarTech.com’s MXT101MMHQ.

When you troubleshoot issues with a video extender, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • Video and Ethernet cables

  • Video extender

  • Video source (such as a DVD player or computer)

  • Video destination (such as a monitor or projector)

Note: When you are testing setup components, you should avoid using video adapters. For example, if you are converting a VGA source to HDMI for use with an HDMI extender, you should use an HDMI source when you test the components.

To test your setup components, try the following:

  • Use the cable, video extender, video source, and video destination in another setup to see if the problem is with the components or the setup.

  • Use a different cable, video extender, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

  • Test each cable individually.

  • Use short cables when you are testing.

When you test the video source and video destination, it is recommended that you do the following:

  • Remove the video extender from your setup and test to make sure that the video source and video destination work together without the video extender.

  • Test to make sure that the video source and video destination work together at the resolution that you want to use.

Note: In order for your setup to work properly, the video source, extender, and destination all need to support the resolution that you are using.

This device supports up to 4Kx2K resolutions @30 Hz with a color depth of 8 bits. If you are running a 4K resolution at a refresh rate higher than 30 Hz or a color depth higher than 8 bits, your display will appear blank.

To resolve this issue, you need to lower the resolution, refresh rate, or color depth, by completing any of the following:

  • Connect a display to OUT 1 that is only capable of 4K at 30 Hz with a color depth no higher than 8 bits.  
  • Connect the least capable display to OUT 1.
  • Connect an additional display to your video source (for example, a video card in a computer) and use this display to reconfigure the display connected to OUT 1 to run at 30 Hz and 8 bits color depth (or lower).

Before You Buy

If you need to use a video extender with a video adapter or converter, you should position the adapter or converter as close to the video source as possible. For example, if you need to take a VGA signal from a computer and send it 200 feet to an HDMI® projector, you should convert the signal from VGA to HDMI and use an HDMI extender.

Note: For more information on when to use cables or extenders, see the following FAQ: http://www.startech.com/faq/video_signal_converters_when_to_convert.

Yes, this video extender works with set-top boxes, provided the set-top box meets the following requirements:

  • The set-top box must be High-bandwidth Digital Content Protection (HDCP) compliant.
  • The set-top box must support devices being connected between the video source and display. If the set-top box requires a direct cable connection between the video source and display, it won't work with this video extender.

No, this device is designed to be a point-to-point solution using networking cabling only. 

This device outputs HDMI video signals. If you have a display or video destination that uses another type of video connection, there are ways that you can convert the video signal or connection. These options are outlined below and organized by the target connection.

HDCP

When you consider whether to convert an HDMI video signal to another connection type, it is important to know if the media that is being converted from the HDMI video connection is protected by High-bandwidth Digital Content Protection (HDCP). If the media is protected by HDCP, you cannot convert to analog video connections because they do not support HDCP. You may experience this issue when you use devices like Blu-ray players, DVD players, and certain gaming consoles.
