Overview of Remote Control
USB Remote Control System
USB Port Types
There are two standard types of USB ports. The external controller (PC) must
be connected via the USB host port (type A), while the E4980A/AL and other
USB-compatible devices must be connected via the USB interface port (type
mini-B).
Preparing E4980A/AL
You do not have to configure any softkey or command for the E4980A/AL in
order to control the E4980A/AL from an external controller. Simply connect a
USB cable to the USB interface port.
Preparing External Controller
You must set up the I/O interface of the external controller in advance to
establish communication with the E4980A/AL via a USB. The USB can identify
devices automatically, so once you connect a USB cable to a target device, a
dialog box will appear for USB device registration.
The E4980A/AL will be identified as a new device if its serial number has
been changed.
