Chapter 4: Configuration
USB Hub Size
Select either a 13 or 7 port USB hub. This determines the number of USB devices that can be connected to a single Transmitter.
Note: It is not possible to reserve USB ports on the transmitter when used with iPATH Agility Controller.
Enable Dummy Boot Keyboard
It is often necessary to have a keyboard reported at start up. This setting means that a "Virtual Keyboard" is always reported to
the USB host. It may be necessary to disable this for use with some KVM switches.
Reserved USB ports
This setting lets you set aside a specific number of USB ports (up to 8) on the transmitter that can be made available for certain
USB devices which require a quirk setting under advanced usb features, connected to a receiver.
Note: This setting can only be applied globally it is not found with individual transmitter configurations because all receivers need
to know how many USB ports are available for the advanced USB features.
Serial port options
These allow you to match the serial configuration being used by the attached PC host.
