Frequently Asked Questions - SM-EHD Smart-AVI
How do I connect the Smart-AVI SM-EHD extender?
Connect the transmitter to the HDMI source with an HDMI cable, and the receiver to the display. Then link the two units using a Cat5e or Cat6 Ethernet cable. Finally, power both units with the included 5V DC adapters.
Does the SM-EHD support 4K resolution?
Yes, the SM-EHD supports 4K@30Hz and also 1080p@60Hz. For the best performance at 4K, use Cat6 or higher cable and keep the distance below 35 meters.
What is the maximum transmission distance?
The maximum supported distance is 50 meters over Cat6 cable. When using Cat5e, the reliable distance may be reduced to about 40 meters.
Can I use Cat5e instead of Cat6 cable?
Yes, you can use Cat5e, but the maximum distance and resolution may be limited. For 1080p, Cat5e works well, but for 4K we recommend Cat6.
Does the SM-EHD support audio return or ARC?
No, this model does not support ARC (Audio Return Channel). It transmits audio along with the HDMI video signal from the source to the display.
What should I do if there is no signal at the display?
First, check that both units are powered and the LED indicators are lit. Verify the HDMI source is outputting, and that the Ethernet cable is securely connected. If needed, try a different cable or display.
Is HDCP supported?
Yes, the SM-EHD is HDCP 1.4 compliant, which allows you to stream protected content from devices like Blu-ray players and streaming boxes.
Can I chain multiple SM-EHD units to extend over longer distances?
This extender is not designed for daisy-chaining. To extend longer distances, use an Ethernet switch between the transmitter and receiver, but each pair will add latency. For best results, keep a single segment within the rated distance.
What power supply does the SM-EHD require?
Each unit requires a 5V DC, 1A power supply. The package includes two adapters. Using a different voltage may damage the device.
How do I reset the SM-EHD?
To reset, simply power cycle the device by unplugging the power adapter for 10 seconds and plugging it back in. This will restore default behavior. There is no external reset button.
