SCU-17

SCU-17 USB interface for Data Modes and CAT control.

The Yaesu SCU-17 is a USB Serial Port and Sound Card interface for Yaesu Transceivers. It provides dual serial ports ( one for CAT and one for FSK/PTT Control) and a PC Sound Card for Data modes like PSK-31/63, JT65 and FT-8. It comes with a USB lead for connecting to the PC/ Laptop and both Data and Serial Port cables for connecting Data and CAT leads to the radio.

The SCU-17 provides CAT communications through a USB Terminal and Audio Input and Output through a USB Sound Card.

One Serial port is used for CAT control for any Yaesu radio not having a built in USB connection. The second serial port is used for FSK keying in RTTY and PTT using the DTR and RTS signals via the Data Connector on the back of the radio. Non Yaesu Radios can also be interfaced to the SCU-17 using the 2 x 3.5mm jack sockets for Audio In/Out and FSK/PTT.

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 operates from the USB bus power, so no external Power supply is requierd.

For RF isolation, the SCU-17 is designed with optoisolated 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 level controls on the front panel, for convenient level adjustment with LED indictors on the front panel to indicate the status of the PTT and FSK lines.
