HI sirs;


We have just recently acquire a CAC-1332 adapter. We want to connect hdmi port portables to the Jabra connection hub (technical info HERE) connected to the hub we have an hdmi smartTV. The laptops are Asus VivoBook 14 M413DA EB462. The issues is that when we connect the adapter it works well for around 3-5 min and after doesn´t work any more even if we are disconnecting it from the laptop and reconnecting again. We need to reboot the laptop in order to get the adapter working again.


How we can solve this??

It is not recommended to use active adapters via Docking stations. Better use is directly into the Source

In this case this is not a solution. The connection hub is part of the Jabra videconference system and we can not take out

What is the HDMI smartTV?

Just to be sure you connect CAC-1332 to the Jabra and then run a USB-C Cable to the SmartTV? Does the USB-C support data/video?

The Asus VivoBook support USB-C Alt mode?

Gathering info we might be able to come up with a solution together.

Hi and thanks for the reply.

The smart TV is a Samsung UHD 2020 75TU8005.

The jabra connection HUB has an embeded USB-C input where the CAC-1332 is connected.

This USB-C cable can support the following modes:

USB-C DP Alt Mode. Requires compatible USB-C DisplayPort and
Alternate Mode PC port.


From the Jabra Connection hub we run an hdmi cable to the smart TV.

HDMI resolution up to [email protected] & VGA resolution up to 1920×[email protected].


The Asus Vivobook has an USB-C port that only support data HDMI resolution up to [email protected] & VGA resolution up to 1920×[email protected].


That is why we need to use as video output the Asus Vivobook hdmi port.

Let me know if you need more info.

The full connection is:

VIVO-> CAC-1332 -> USB-C cable -> JABRA -> HDMI 2.0 cable -> Samsung UHD 2020 75TU8005.


The CAC-1332 is not designed to support a dockinstation but displays. It is a power issue and this is why nothing but a reboot of the system will work. You are trying to mimic a USB-C Alt mode port on the VIVO to get the JABRA to work. It will not work this way.

Why not connect a USB-A to USB-C to the JABRA. And then a direct HDMI connection to the VIVO and Samsung TV? Assuming the VIVO does have a USB-A.
