I ordered this HDMI switch from CE*Compass. It came by mail in less than a week with the Super Saver shipping. But the switch, IR remote sensor dongle, and remote control were stuffed into a padded envelope without any instructions. I emailed the seller who replied within 2 hours with basic information but without sufficient instructions to take full advantage of the features of this device. So this morning I began the Google search for information. In case you are in a similar situation or you are considering buying this HDMI switch, here's how it works:
There are 3 switching method choices:
Manual: press button on unit to step through the inputs as indicated by the LEDs.
Remote: attach the external IR receiver and select the input via the remote control.
Automatic: the switch will automatically select the "live" HDMI input; if more than one HDMI input is "live" the input with the smaller number will be selected; if you have a device that is always live, put it on HDMI input #3.
* Most HDMI output devices only power the HDMI output or are "live" when the device is turned on. A few devices output power through their HDMI port if they appear to be turned off. These devices' HDMI output is always "live". If you have more than one input that is always "live" you must use Manual or Remote switching to select between the two always "live" devices.
* You can determine if a device outputs a "live" HDMI even when the device appears to be turned off by observing the switches response to your connecting the device. If you plug in a device that is turned off and the switch selects it and illuminates it's LED, then this device's HDMI output is always "live".
