How to Confirm the Installation, and the COM Port Number
With the SCU-17 and computer connected, confirm whether the virtual COM driver has been installed successfully.
The example below is for Windows
®
1. Click the Windows "Start" button → Right-click "Computer" → Click "Properties (R)".
2. Click "Device Manager" on the window that appears.
3. On the Device Manager screen, double-click "Port (COM & LPT)".
The SCU-17 provides two virtual COM ports: an Enhanced COM Port and a Standard COM Port. These ports offer the
following functions.
r CAT communications Enhanced COM Port
r PTT control (RTS)
r FSK control (DTR)
Select the COM port numbers that were confirmed using the above procedure when performing software port configura-
tion.
When operating RTTY, set the Sound Card (input) setting to "USB Audio CODEC".
When operating DATA, PSK or AFSK modes, set the Sound Card (input and output) settings to "USB Audio CODEC".
Caution:
r If a "!" or "X" is displayed for the port on the Device Manager, uninstall and reinstall the virtual COM driver.
r If an SCU-17 with a different serial number is connected and turned on, different COM port numbers will be as-
signed to it, making it possible to perform individual COM port configurations for an additional SCU-17.
r When using the USB cable to perform TX control, the transceiver may switch to transmit mode when the computer
is started.
r Always shut down the application on the computer before disconnecting the USB cable.
