TIPS FOR THE USB PORT SETTINGS

SECTION 2 ABOUT LINK SETTING FOR BETWEEN USB
PORT AND REMOTE JACK
Applicable products: IC-7300, IC-7851 (as of March 2016)
You can switch USB port and [REMOTE] link ON and OFF in the above Icom’s amateur base transceivers.
In case the transceivers that two COM ports are recognized, the link setting is available for only USB1.

The default setting of this item is “Link to [REMOTE].”
This setting is selected when using the Transceive function by outputting the control signal from [REMOTE]
after converting the communicating data at the USB port to CI-V data, or when operating the existing remote
control system with the optional CT-17. In this case, the USB port communication speed is limited to 19,200
bps because the [REMOTE] jack’s maximum communication speed is 19,200 bps.
Thus, Icom strongly recommends the setting of "Unlink to [REMOTE]" in cases other than those above.
By using “Unlink to [REMOTE],” you can operate the USB port with a speed of up to 115,200 bps.

IMPORTANT: Set to “Unlink to [REMOTE]” when using the spectrum scope function of RS-BA1 with the IC-
7300, or IC-7851 through a USB cable. Otherwise RS-BA1 spectrum scope will not function since the data
transfer speed of the USB port is insufficient for the amount of data required by the spectrum scope.
