The IC-7610 has two virtual COM ports, A and B.
When connecting to a USB port on your PC, the ports
are virtually named as USB1 (A) and USB1 (B), and
then the transmit and receive control (USB SEND),
CW Keying, or RTTY (FSK) Keying signals from the
PC are assigned to the DTR/RTS terminals in the
virtual port.
TIP: About the USB SEND/Keying items
L
When you operate RTTY or CW through your PC’s USB
port and your IC-7610, you may not be able to send the
“SEND” or “Keying” signals until a few seconds after
you connect the USB cable.
L
When you operate through your PC’s USB port and
the IC-7610, and connect a second transceiver to
another PC USB port, a short “SEND” or “Keying”
signal will be sent from the irst transceiver. Therefore,
we recommend that you do not connect a second
transceiver to a USB port of the same PC. Or, always
turn OFF the transceiver power before you connect a
USB cable.
