4.2USER-PROGRAMMABLE FEATURES

You may program the Sampling Setup, Reporting Setup, and Dynamic Configuration on the PDI which are discussed in Section 4.2.1 through Section

4.2.3respectively.

4.2.1SAMPLING SETUP

Sampling Setup allows you to program the Debounce Delay and Latch Polarity for the input channels. The Debounce Delay is used to guard against erroneous events. An event will not be valid unless the input channel has remained at a changed state for the debounce duration. The debounce delay may be programmed from 0 (for no debounce) to 65535 milliseconds. The Latch Polarity is used to latch individual inputs based on a positive going (LO to HI) or negative going (HI to LO) input. The latch information is retained in memory until recalled by the user. The default Debounce Delay time is 100 milliseconds and the default

Latch Polarity is a HI to LO transition.

4.2.2REPORTING SETUP

Reporting Setup allows you to program how the PDI reports event samples to the host module. The items you may program in the Reporting Setup include Reporting Method, Report Start Time, Report Interval, Set Host Address, Data Format, Time Tag, and Terminating Character(s). The following subsections describe these features in more detail.

4.2.2.1 REPORTING METHOD

Reporting Method is the manner in which event samples are sent to the designated host module. The PDI provides three Reporting Methods: Command (upon request via data commands), Immediate (upon exiting configuration), and Schedule (where reporting begins at a specified time). The default Reporting

Method is Command.
