Pins 1–5 These indicate details regarding the current condition of the unit. A “1”

corresponds to a “high” level on the corresponding pin.

Pins 7–8 These can be used to select Voiceover and Switched Out modes. The state of the pins is normally high (internal pull up), and they detect a high-to- low transition. A held contact closure between pins 7 and 9 (ground) or pins 8 and 9 is required to activate a function. A low-to-high transition (i.e., a switch release) restores the delay out setting. The table below shows the function of the two GPI pins on the DP572.
