IR CODES In the event of IR conflicts, please do the following: 1. Remove the battery cover from the back of the RMT16-IR remote. 2. Locate the Dip Switches above the batteries 3. Switch the Dip Switches on the RMT16-IR to any of the combinations pictured below. 4. Dip Switches 1 and 2 in the RMT16-IR correspond with Dip Switches 1 and 2 inside the 4x4 DVI Matrix respectively. Switch the switches inside the 4x4 DVI Matrix to match the same Remote Channel as the RMT16-IR.
DIP SWITCH GUIDELINES Underneath the 4x4 DVI Matrix are two banks of Dip Switches. Below is a table describing their functions. By default, the Bank of 8 switches are set of to the Off position and the other bank of 4 switches are set to ON.

TERMINOLOGY DDC Short form for Display Data Channel. It is a VESA standard for communication between a monitor and a video adapter. Using DDC, a monitor can inform the video card about its properties, such as maximum resolution and color depth. The video card can then use this information to ensure that the user is presented with valid options for configuring the display. DDWG Digital Display Working Group DDWG are the creators of the DVI specification. DVI Digital Visual Interface.
TROUBLESHOOTING If there is any video noise that appears on your output displays, you can resolve them by using the methods described in this section. AUTO EQUALIZATION Auto equalization is set to ON by default, but in some cases you may have to manually equalize the incoming source signal to eliminate video noise that occurs.
