A typical use case will be the need to switch a logic control output, dependent of the zone selection of a callstation.

The following example shows how a logic control output is configured if zones 1 and 2 are selected and the 'Talk' button is pressed.

Configure a logic control output of a station:

  1. Activate the 'Enabled' checkbox
  1. Set the Function to 'Keypad Led'
  1. Set the 'of Station' to the callstation station id
  1. Right-click on the led index field (default value = 1) and point to the 'Talk' button

Configure two additional logic control outputs which will point to 'Zone 1' and 'Zone 2' buttons. The logic control outputs 1, 2, and 3 can now be used to display this status information:

  1. Activate the 'Enabled' checkbox
  1. Set the Function to 'Logic Operation Outputs'
  1. Set the Led Mode 'LED / BU / Mode / SysVal' to “AND”
  1. Set the Audio Out/In to '0' (inputs/outputs 1 to 8 are addressed).
  1. Set 'Input/SysVarID/Feed/Level/Led' to 7, i.e., the BCD-coded representation of the first three outputs (OUT 1=1, 2=2, 3=4, 4= 8, 5=16, 6=32, 7=64), 1 + 2 + 4 = 7.

This procedure also works for logic control inputs.
