TIP: Always use serial PTT instead of the radio command PTT or VOX. It is the only sure way to
assure proper sequencing of an LNA and Power Amplifier.
To test basic operation of the PTT from the computer to the radio, click on the Test button with no port
addigned orthe port closed. More details about function check are described in chapter 12.2
2 nd PTT Port
The second PTT channel is identical to the primary PTT channel.
Squelch Port
Even though most current applications do not support readback of squelch and do not have the ability to
perform specific functions based on its status, we have decided to include this feature in Router. Perhaps
someday applications will be able to detect the squelch and use this information for configurable
automated functions like audio recording.
Router allows assigning a virtual serial port to squelch as CTS, DSR, DCD or RING..
When a COM port is assigned to the squelch channel in Router but not in the application (or no application
is running), Router shows the channel as closed.
When an application opens the COM port (usually at start-up), Router shows channel as open.
When squelch is active, this state is indicated by a red arrow.
