Parallel Console Check Box

PTT Notch Filter Check Box

The PTT Notch Filter checkbox, when selected, indicates the 2175Hz notch filter is enabled. When selected, 2175Hz ±180Hz frequency range is filtered during PTT. Use this option when 2175Hz is blocking desirable audio.

PTT Setup

The PTT Setup section allows a secondary external function to be controlled with a separate relay closure at the same time as the PTT relay. Select one of the following:

PTT relay only – When selected, only the PTT relay is closed. (Default Setting)

PTT + R1 –	When selected, both the PTT relay and the R1 relay close at the same time.
PTT + R2 –	When selected, both the PTT relay and the R2 relay close at the same time.
PTT + BOTH –	When selected, the PTT relay, the R1 relay, and the R2 relay close at the same time.

PTT Timeout Field

The PTT Timeout field is used to indicate how long, in seconds, to allow PTT to be active when no audio is transmitted. If a time is entered in the field, PTT activity will timeout after the designated amount of time has lapsed. This feature is useful in cases where the line goes offhook for an indefinite period of time due to a stuck PTT key.

The range for this field is 0 to 1800sec. To disable this feature, enter zero (0).

Serial Port Mode

Serial Port Mode Drop Down Menu

The Serial Port Mode drop down menu, shown in Figure 100, is used to identify the specific radio interface for the serial port configuration. Selecting an item with a Scan List suffix enables a frequency scan list update function. The freq scan list function synchronizes the console scan list with the radio's scan list.

By default, the serial port in Tone or Console mode is Normal.
