Inhibit Timer at USB Connection (Default: ON)
Turns the timer for SEND or Keying signal transmission
ON or OFF.
When using a PC with an old USB driver installed, and
an IC-7300 through a USB cable, turning ON the timer
prevents an unintentional sending of the SEND or Keying
signal when:
• Connecting a USB cable to the PC and IC-7300.
• A
virtual serial port communication is established.
• Starting up the PC while it is connected to the IC-7300.
• Connecting or disconnecting another USB device to or
from the PC, while the IC-7300 is connected to the PC.
OFF: Sends the SEND or Keying signal immediately.
ON: Pauses for a few seconds before sending the signal.
L If you change this setting to “OFF,” rst update the
transceiver’s USB driver and make sure the SEND or Keying
signal will not be unintentionally sent.
