XD150: Mode Switch Settings

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.

 Note

The default position for both switches is UP, thus selecting Long reach mode and high speed (normal) USB mode. Changes to the mode switches are not recognized until you re-apply power to the local module.

USB compatibility mode

Switch A — Determines whether USB compatibility mode should be used.
UP - Normal mode - 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 - 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.

 Note

When high rate mode is used, the modules will continually check the link quality to ensure that it is capable of supporting the higher pixel clock. If excessive data errors are detected, the modules will fall back to Long Reach mode until the local module is reset or the link is broken and re-established.
