Physically reset the keyboard and mouse port by unplug the KVM cables from the RLK150’s System Ports.  Turn off the master power switch from the back of the RLK150.  Reconnect the KVM cables to the RLK150’s system ports. Power on the master power switch. 

RLK150 unit is fully functional. But when connect to certain computer, there is no screen.

The video port of the computer might be output video signal out of the RLK150’s LCD display specification. See “RLK150 LCD Display Specification” section for more information. This is a video card compatibility issue.

Replace the computer’s video card that supports the display mode listed on the “RLK150 LCD Display Specification”

RLK150 unit was fully functional after the initial installation. But after few hours, I can no longer see some of the computers’ screen when switching between video ports.

Some of the computers might be in the Green Energy Saving Mode or “Sleeping Mode”.  The computers had stopped sending video signals to RLK150.

Pressing the computers’ power ON/OFF button or the special “Sleep” button to wake up the units.
