Firmware update information— Ver. 1.30
Thank you for using the Icom Download Service.
Version 1.30 of the firmware will provide the following additional functions or changes to your IC-7850/IC-7851.
➥The default settings of the IF filter and Roofing filter are changed.
➥A SSB-D TBW item is added on the Level set screen.
➥A USB SEND/Keying Inhibit at Connection item is added on the Others set screen.
➥CI-V commands are added (pp. 2, 3).
Before updating, see Section 17 ‘UPDATING THE FIRMWARE’ in the IC-7850/IC-7851 instruction manual, for
details.
IMPORTANT!
Make a backup file of the transceiver’s settings, such as stored memory channels, filter settings, to the SD
card or USB flash drive before updating the firmware.
The CPU will be automatically reset when the firmware update is done, the transceiver’s memory contents
will be cleared and ALL settings will be returned to their default settings.
■Changed default settings
The default settings of the IF filers (FIL1 ~ FIL3) and
Roofing filter in the SSB-D mode are changed. (The
changed items are shown in bold in the table below.)
DIF filter
Mode IF filter (default) Selectable range (steps)
SSB-D
FIL 1 (3.0 kHz)50 Hz to 500 Hz (50 Hz)/
600 Hz to 3.6 kHz (100 Hz)
FIL 2 (1.2 kHz)
FIL 3 (500 Hz)
DRoofing filter
Mode IF filter (default)
SSB-D
FIL 1 (15 kHz)
FIL 2 (6 kHz)
FIL 3 (6 kHz)
■Addtional set items
The SSB-D TBW item is added on the Level set
screen and the USB SEND/Keying Inhibit at Connec-
tion item is added on the Others set screen.
SSB-D TBW (Default: 300 – 2700)
Sets the transmission pass bandwidth to the SSB-D
mode, by changing the lower and higher cut-off
frequencies.
• Lower frequency: 100, 200, 300 and 500 Hz
• Higher frequency: 2500, 2700, 2800 and 2900 Hz.
USB SEND/Keying Inhibit at Connection
(Default: ON)
Turn ON the timer to prevent unintentional SEND or
Keying signal transmission if the USB driver version is
not the latest one, under the following conditions.
• When connecting a PC to the IC-7850/IC-7851 using a
USB cable.
• When a virtual serial port communication has been
established.
• While the IC-7850/IC-7851 and a PC are connected
using a USB cable, or when starting up the PC or
connecting or disconnecting a USB device to or from
the PC.
• OFF: The IC-7850/IC-7851 transmits the SEND or
Keying signal right after a PC or USB device
is connected.
• ON: The IC-IC-7850/IC-7851 transmits after a few
seconds have passed, to prevent unintentional
transmission.
LIf you change this setting to “OFF,” update the
transceiver’s USB driver and make sure the SEND or
Keying signal will not be unintentionally transmitted.
