10. Push Buttons Four pushbutton switches are located on the front bezel directly under the display Pushing a button generates a start event packet and releasing it generates an end event packet Event packets sent to the host contain the switch number activated 1 is leftmost switch and 4 is rightmost switch thus the host computer can make decisions based on the particular switch pushed The time the button is pressed and held down can be measured by setting the start and end event masks and reading the number of 10 millisec clock ticks between them For example this could be useful in an application that uses the difference between a short press and long press Set start mask Set end mask only if required for timing Start Event and End Event Masks Start and end event masks are modes that can be setup with UnitConfig The values consist of 8 hex digit 32 bit masks that define the type of device initiating the event as shown in the table below Factory default is all masks disabled 00000000 Start and end masks are always present in the transmitted packet but one is always disabled For most applications the end event mask is not required and it should be left disabled A start event is a complete packet and an end event is a complete packet Set the mode values mask settings as shown in Table 1 May1 06RevC Page 34 SVLiteModels TM47 TV42 5206E User Guide M38506 01C Industrial Electronic Engineers Inc
