Specifications

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

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.
