Description of RAD-Moon Interfaces and Indicators
Let’s now take a short tour of the RAD-Moon, looking at the device’s external components
and explaining what each does. The RAD-Moon is designed so that all of its components are
located on its two sides, to make the device easier to use in cramped quarters. We’ll identify
the sides by the type of Ethernet port each contains, calling one the
Conventional Ethernet
Side
and the other the
Automotive Ethernet Side
.
Conventional Ethernet Side
Figure 2 shows the side of the RAD-Moon that attaches to a conventional Ethernet network.
The two components are as follows:
•
RJ-45 Port:
An industry-standard conventional Ethernet jack.
•
Mini-USB Port:
A standard mini-USB port.
Figure 2: RAD-Moon Conventional Ethernet Side.
Left, the standard Ethernet RJ-45 jack with integrated
Link
and
Activity
LEDs; right, a mini-USB jack that provides power to the device.
The RJ-45 port has a pair of integrated LEDs that provide information about the RAD-Moon’s
conventional Ethernet connection:
•
Link LED (Green):
Indicates that a valid link has been established between the RAD-
Moon and another 10/100 Ethernet device.
•
Activity LED (Orange):
Flashes when traffic passes in either direction over the
attached Ethernet cable.
In normal operation you should see the
Link
LED always on, and the
Activity
LED flashing at a
variable rate, with faster flashing meaning that more data is being transferred.
