Virtual Com Port Driver - Kenwood TS-990S In-Depth Manual

Virtual COM Port Driver

If the TS‑990S is connected to a PC using a USB cable, a virtual COM port driver must be installed to use the
ARCP‑990, ARHP‑990, and/or other application software which can control the TS‑990S through the RS‑232C bus.
For connection of the TS‑990S to a PC using an RS‑232C or LAN cable, a virtual COM port driver does not need to be
installed onto the PC.
Likewise, for use only with the ARUA‑10 by connecting the TS‑990S to the PC using a USB cable, a virtual COM port
driver does not need to be installed onto the PC. In the case when only the USB sound function implemented in the
TS‑990S is used, the standard drivers installed in Windows are employed.
To confirm which COM port number the USB port of the TS‑990S is allocated in the virtual COM port drive, open the
Device Manager window of Windows and expand "Port (COM and LPT)".
"COMxx" of "Silicon Labs CP210x USB to UART Bridge (COMxx)" indicates the COM port number allocated in Windows
for the virtual COM port driver.
In the following example, "Silicon Labs CP210x USB to UART Bridge (COM3)" is indicated. In this case, "COM3" is the
COM port number allocated to the virtual COM port driver

The COM port number will change upon reconnecting a USB cable to another USB port of a PC that is connected to the
TS‑990S. To view the COM port number, repeat the above procedure.
