Cables for Yaesu FT-891

Unlike other transceivers in FT-8xx lineup, Yaesu FT-891 does not expose the serial interface lines and instead implements serial CAT internally via its own USB connection.

Only the cable with MiniDin6 connector is needed on the transceiver side. Plugged into Digirig’s audio port it takes care of minimum feature set required for digital modes: audio and PTT. The PTT switch is controlled via the RTS signal of Digirig’s COM port.

The cable is available as part of Yaesu FT-8xx cables kit.

If optional serial CAT control is desired, it can be added via the direct USB connection between the transceiver and computer:

Because Digirig’s serial interface is not used for data transfer in this arrangement, the interface can be in any configuration. More information on configurations can be found here.

Transceiver settings information and connector pinouts can be found in the advanced user manual.
