Connecting Cyclone-to-PC via an Ethernet cable
cable, is used to connect devices of different types together, such as a PC to
a Hub, or a Hub to a Cyclone. At this point it once again becomes necessary
to program the Cyclone with valid IP numbers, the process for which is
described in greater detail in the following section. However, it is important for
the Cyclone and the PCs to have matching Subnet and Gateway IP numbers,
and for each to have a unique IP number on the network. An example of a
setting for above is as follows:
PC1
PC2
CYCLONE
Gateway
It is important to briefly touch upon the underlying network architecture, which
can be a 10Mb (Megabit), 100Mb, 10/100Mb, half-duplex, or a full duplex
connection. The details of the underlying network architecture are beyond the
scope of this document, but it is sufficient to note that most modern network
cards, as well as the Cyclone device, have the capability to configure
themselves for the underlying network through the Auto-negotiation
mechanism. Auto-negotiation is performed as soon as a network cable is
connected to the device, and it sets the operating parameters of the device to
match those of the network.
In order to connect the Cyclone to a PC directly via an Ethernet cable, you
need to use what is known as a cross-over cable. A cross-over cable, which is
not provided by P&E, is normally used to connect two similar devices such as
a PC to a PC, or a Hub to a Hub. It is a cable that has its receive and transmit
wires crossed over so that the similar devices can effectively communicate
with one another.
With this configuration, it is still important to assign IP numbers to both the PC
and the Cyclone device. Although at first glance it may not seem necessary to
assign a Gateway address in this configuration, the Cyclone was designed to
operate on a network of more than two computers, and therefore it needs to
be programmed with a Gateway address.
