SCU-17 USB InterfaCe UnIt 1
Introduction
The SCU-17 interface unit may be used for CAT control of the transceiver with
a computer via a USB connection; and for communications using SSTV, RTTY
and PSK digital modes.
Note: YAESU does not produce CAT, SSTV, RTTY and PSK System operating
software, due to the wide variety of personal computers, operating sys-
tems, and applications in use today.
The SCU-17 provides CAT communication through the USB terminal when a
PC does not have an RS-232C connection.
The SCU-17 is equipped with a USB audio system device, so the TX and RX
audio system signals are accessible to the SCU-17 through the USB cable.
Therefore, the supplied USB cable is the only connection needed between
the SCU-17 and PC.
The SCU-17 is equipped with a two-channel USB serial device and enables
the various transmission modes and the CAT communication simultaneously.
The SCU-17 operates from the USB bus power; you do not need to prepare
an external power supply.
For RF isolation, the SCU-17 is designed with photo relays for the PTT/FSK
terminals. AF transformers are used in the AUDIO IN/OUT lines to provide
excellent ground isolation.
The SCU-17 is equipped with the TX and RX audio controls on the front pan-
el, for convenient level adjustment.
LED indicators on the SCU-17 front panel monitor the PTT and FSK control.
The operating conditions may be quickly conrmed.

Virtual COM port driver Installation
Install the virtual COM port driver on the personal computer before using the
SCU-17 USB interface unit.
Please see the USB Driver (Virtual COM Port Driver) on the Yaesu Website for
details refer to (http://www.yaesu.com/) in the FTDX1200 product les section.
Note: Do not connect the USB cable and SCU-17 to your personal computer
until after the “virtual COM port driver” installation is completed, because
an incorrect driver may be installed.
 For assistance with the software port conguration, refer to “How to Conrm
the Installation, and the COM Port Number” in the “Virtual COM port Driver
Installation Manual”.
 For information on port conguration for commercial and free computer soft-
ware, refer to the manual for the software being used.
When using the USB cable to supply TX and RX audio signals, set the
Sound Card (input and output) settings to “USB Audio CODEC”.
When using the USB cable for computer TX control, the transceiver may
switch to transmit mode when the computer is started, etc.
YAESU does not provide technical support for the use or operation of com-
mercial or free computer software.
