Every device configuration dialog shows generated UMR200 input configurator on first tab.
The logic is generated from annotations in https://git.digitalstrom.org/dss/dss-mainline/blob/509685fabb9a23373ea471c240394a5af614468c/src/view/device-config.capnp.
The logic is implemented in angularjs and integrated into extjs rendering elements.
The edited value is hardcoded, not loaded from device for now.
