PathFinder Version 4.22 User Guide15. LOGIC FACILITIES – ADVANCED15.1 Programming System Logics: Inputs15.1.1 OverviewSystem logic inputs are only available when the matrix has a GPI card installed. Please referto Chapter 6.3 for information on adding a GPI card to the PathFinder GUI.From Version 4.15 onwards, the logic input form has been extended. The “AdditionalFunctions” field has been split to show logic o/p and 4-wire port as separate fields. Thisgives improved flexibility in programming, since a logic input can now be used to target alogic output and set up a 4-wire call. An extra text field has also been added (labelledcomments) which should be used to explain the functionality of the logic programming.The form also reports any logic inputs assigned to IFB’s (see Chapter 15.1.5).15.1.2 Logic Inputs triggering Crosspoint ListsA logic input triggering a crosspoint list is used as a means of remotely controllingcrosspoints within the matrix. A typical example could be a logic input from an On Air switchto prevent audio being routed to the studio floor talkback loudspeaker when the studio istransmitting. Another example could be a simple panel using switches wired to the GPI cardlogic inputs to route audio from its panel microphone to the required destinations within thematrix.15.1.2.1 Programming logic Inputs triggering Crosspoint ListsProgramming a logic input to trigger an inhibit list is a two part operation.1. Set the crosspoint to be controlled in the Crosspoint List menu.2. Set the logic input to target the crosspoint list.Trilogy Communications LimitedIssue 1Page 85 of 85
