IR CODE CONFIGURATION

Why would I need to change the remote channel?

In some instances, the 4x2 Switcher for HDMI may use IR codes that conﬂ ict with

other IR remote control devices. The unit may switch inputs when another brand IR

remote control is used or the RMT-4IR may cause other brand IR controlled devices

to behave unexpectedly.

I am experiencing the issues listed above. What do I do?

In these cases it is recommended to change the IR channel that the RMT-4IR

remote control and the 4x2 Switcher for HDMI use. The IR channel is conﬁ gured

independently on the RMT-4IR remote control and the 4x2 Switcher for HDMI but the

channel selection must match on both units for proper operation.

How Do I change the Remote Channel?

There are service DIP switches on the RMT-4IR remote control and also inside the

4x2 Switcher for HDMI. Use the diagrams below to locate and change the IR channel

to one that is not the default. Remember that the channel must match on both the

unit and remote control for successful operation.

Remove the battery cover on the rear side of the RMT-4IR remote control

to expose the DIP switches.

The IR channel DIP switches for the 4x2 Switcher for HDMI are located on an 8 bank DIP switch inside

of the unit and on its main-board. To open the unit, remove all screws on the underside and side of the

unit. Remove all HEX screws on the rear panel. This includes the screws above each HDMI port and on

each side of the RS-232 serial communications port. Carefully slide the unit apart. Locate DIP switches 3

and 4. Once adjustments are complete replace all screws and.
