Out of the box, each CATX-Module has a built-in EDID that supports a default set of resolutions. When the host computer boots, it reads the EDID directly from the CATX-Module, which determines which resolutions are available on its operating system.
To update the CATX-Module with the actual monitors EDID, which may offer different resolutions, the monitor, X200, CATX-Module and host need to be switched on in a particular order to pass the EDID down the chain. The following instructions assume that the cables are physically connected between each of the components.
- Power up Monitor
- Powered on X200.
- The X200 will read the EDID from the Monitor.
- Power on the host computer.
- The host computer will, in turn, provide power to the CATX-Module, either via the PS/2 connection or USB depending on the model.
- The CATX-Module will read the EDID from the X200 and store it locally.
- The host computer will then read the EDID directly from the CATX-Module.
The gif animation below, demonstrates how the EDID is passed from the monitor to the host computer, as each component is turned on.
