The local module has two small switches on its rear panel. These are used to determine which operation modes should be used. You will need to re-power the local module whenever a switch setting is changed.
Switch A — Determines whether USB compatibility mode should be used.
UP - Normal mode (default) - Use this if the modules are not connected to a KVM switch.
DOWN - Compatibility mode - Use this if either the local or remote modules are connected to a KVM switch. This mode ensures robust and reliable operation with KVM switches but also reduces the maximum USB data rate.
Switch B — Determines the priority for the data link: Longer distance or higher screen resolution.
UP - Long reach mode (default) - Limits the pixel clock (148.5MHz) so that longer stretches of link cable (exceeding 100m) can be used. This will restrict the achievable screen resolution to a maximum of 1920 x 1080 at 60Hz (aka ‘1080P’).
DOWN - High rate mode - Allows a higher pixel clock (165MHz) to support screen resolutions of up to 1920 x 1200 at 60Hz (aka ‘WUXGA’). This will limit the maximum link cable length to around 100m or less, depending on the type of link cable used.
