INSTALLATION AND CONNECTIONS
■ FSK and AFSK connections
The transceiver has a Modem function for RTTY and
PSK. However, if you want to use a PC to operate
these digital modes, it is necessary to prepare the
following interface circuit, or use a similar 3rd party
device.
Refer to the instruction manual for the device prior to
connecting it.
Transverter connector
■ Transverter jack information
When 2 to 13.8 V is applied to pin 6 of [ACC 2], the
[X-VERTER] connector is activated for transverter
operation and the antenna connectors do not receive
or transmit any signals.
While receiving, the [X-VERTER] connector can
be activated as an input terminal from an external
transverter.
While transmitting, the [X-VERTER] connector
outputs signals of the displayed frequency at –20
dBm (22 mV) as signals for the external transverter.
D When connecting to the USB connector
Connect a USB cable (user supplied) between the transceiver’s USB connector [USB] (B) on the rear panel and
the PC. (p. 19)
• The USB driver and the installation guide can be downloaded from our website (http://www.icom.co.jp/world/index.html).
