Yaesu SCU-17 USB Interface
USB Interface Unit for radio and PC
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.
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 panel, for convenient level adjustment.
LED indicators on the SCU-17 front panel monitor the PTT and FSK control. The operating conditions may be quickly confirmed.
