Station Transponder Unit Configuration

Serial USB PTT Comm Port

This parameter selects the COM port that will be used to provide an external PTT input to

the FSA Server. It is used when the System employs a 950-0690 Audio Input Interface

adapter and a USB cable. The parameter defaults to None. Opening the drop-down list

enables you to select from any of the available COM ports.

Serial USB Comm Port PA Ready

This parameter selects the COM port that is connected to the optional PA Ready Cable

(P/N 709-7929). This COM port and cable provide the PA Ready Signal. The parameter

defaults to None. Opening the drop-down list enables you to select from any of the

available COM ports.

This setting is only useful if you are using the PA Ready option to provide an external PA

Ready indication. For more information, see Installing the PA Ready Option on page 106.

PA Ready Control Signal

This parameter affects the on/off behavior of the PA Ready Signal. The parameter has two

options: positivetrigger and negativetrigger. The correct setting depends on what the

equipment to be connected to is expecting. Select positivetrigger if the connected-to

equipment expects an active high signal. Select negativetrigger if it expects an active low

signal. In general, use negativetrigger for most consoles and positivetrigger for most

lamps. If the parameter is not configured, it shows as blank and defaults to

negativetrigger.

This setting is only useful if you have the PA Ready option. For more information, see

Installing the PA Ready Option on page 106. For a description of its behavior in a

functioning system under various conditions (for example, if Day/Night Mode is in use)

see the Fire Station Alerting System Operation manual, part number 025-9582.

Station Transponder Unit Configuration

Assigning and defining the Station Transponder Units that make up the system is a three-

step process. It starts out with selecting the Fire Station Definitions option from the menu

and continues down through two additional levels of windows to where you assigning

operational units to the station.

Note If CAD is in use, this parameter must be set to a different COM port

than the one being used by the serial CAD input.
