¿Which settings are important to take into account when configuring a layer 2 switch that manages an
In order to extend a video and audio transmission without any transport issues, we recommend turning on the following settings on a layer 2 switch acting as a central node of an ethernet network including VEO video over IP devices :
- IGMP Snooping (Internet Group Management Protocol)
- Jumbo Frame
- 1Gbps
You can get further information on how to configure the switches specially verified by Ecler in the following help guides:
We also encourage you to review the webinar on how to first configure this range of devices.
¿Can encoding and decoding latency introduced in a transmission using VEO video over IP devices (VE
No, latency is given by the encoding and decoding process in the transmitter and the receiver. Audio both from an external source or from the same HDMI input travels embedded in the video stream so synchronicity is not going to be altered in any sort.
¿Will the optic fiber and the RJ45 link included in the VEO-XTI2L / VEO-XRI2L be able to work at the
No, both network links are going to be working one at a time. The connection provided will be active in just one of the links leaving the unused one as a backup for any signal loss that my happen.
¿If we are using the fiber optic link included in VEO-XTI2L / VEOXRI2L, will still be possible to ge
No, the optic fiber link won’t be able to power a device through the twisted pair wire using PoE technology as it is not supported by the standard.
¿Which is the maximum number of screens that can take part in a videowall composition using VEO-XTI2
The total amount of screens cannot exceed 64 units. Also, when in videowall mode, you can add the up until 253 VEO-XTI2L transmitters, the same as in a unicast set up.
¿How does VEO-XTI2L / VEO-XRI2L audio extension work when plugging an external sound source?
When “Line in” input in VEO-XTI2L transmitter is selected using the “Audio” button, the audio signal coming from the external sound source plugged will be embedded on the HDMI video stream overwriting the existing audio flow. If “Line out” or “SPDIF out” is selected using the “Audio” button on the VEO-XRI2L receiver, audio extraction will be available in either of this two audio outputs. The audio will remain embedded on the HDMI video stream as well.
¿How should I configure VEO-XTI2L / VEO-XRI2L for a point to multipoint or multipoint to multipoint
In that case, both the transmitters and the receivers should be working in multicast. Unicast will only be fitted for a point to point solution.

o Average delay appropriate for almost every case
o Not suited for those scenarios where the transmitter and the receiver are placed relatively near and audio is outputted locally in each display device(for example a sports bar or a small conference room)

¿What is the difference between PassThrough and Auto Detect (per EDID) functionalities when configur
Check the image by clicking here:
- Pass-Through: The scaler is not active. VEO-XRI2L receiver outputs the video stream coming from the VEO-XTI2L transmitter as is.
- Auto Detect (per EDID): VEO-XRI2L will output a video stream up or downscaled according to the maximum compatible resolution negotiated by the source and display when first connected.
