runtime purposes. The first two options permit total
freedom of action in selecting network addresses
and use of the “network,” as no action can interfere
with other users. We recommend one of these
options for initial development.
•
No LAN —
The simplest alternative for
desktop development. Connect the Rabbit-
Core’s Ethernet port directly to the worksta-
tion’s network interface card, using an RJ-45
crossover cable. A crossover cable is a special
cable that flips some connections between the
two connectors and permits direct connection
of two client systems. A standard RJ-45 net-
work cable will not work for this purpose.
•
Micro-LAN —
Another simple alternative
for desktop development. Use a small Ether-
net 10Base-T hub and connect both the work-
station’s network interface card and the
RabbitCore’s Ethernet port to it, using stan-
dard network cables.
The following options require more care in address
selection and testing actions, as conflicts with other
users, servers and systems can occur:
• LAN — Connect the RabbitCore’s Ethernet
port to an existing LAN, preferably one to
which the development workstation is already
connected. You will need to obtain IP
addressing information from your network
administrator.
• WAN — The RabbitCore RCM2200 is
capable of direct connection to the Internet
and other Wide Area Networks, but excep-
tional care should be used with IP address
settings and all network-related programming
and development. We recommend that devel-
opment and debugging be done on a local
network before connecting a RabbitCore
system to the Internet.
TIP… Checking and debugging the
initial setup on a micro-LAN is rec-
ommended before connecting the
system to a LAN or WAN.
2.3.4 Connect Power
When all other connections have been made, you
can connect power to the RabbitCore Prototyping
Board.
Hook the connector from the wall transformer to
header J5 on the Prototyping Board as shown in
Figure 2–6 below. The connector may be attached
either way as long as it is not offset to one side.
Plug in the wall transformer. The power LED on
the Prototyping Board should light up. The Rabbit-
Core 2000 and the Prototyping Board are now
ready to be used.
NOTE: A RESET button is provided
on the Prototyping Board to allow
hardware reset without disconnect-
ing power.
To power down the Prototyping Board, unplug the
power connector from J5. You should disconnect
power before making any circuit adjustments in the
prototyping area, changing any connections to the
board, or removing the RabbitCore module from the
board.
2.4 Where Do I Go From Here?
We recommend that you proceed to the next chap-
ter and install Dynamic C (if you do not already
have it installed), then run the first sample program
to verify that the RabbitCore module and Prototyp-
ing Board are set up and functioning correctly.
If everything appears to be working, we recommend
the following sequence of action:
1.
Run all of the sample programs described in
Section 3.5 to get a basic familiarity with
Dynamic C and the RabbitCore module’s
capabilities.
2.
For further development, refer to the Rab-
bitCore RCM2200 User’s Manual for
details of the module’s hardware and soft-
ware components.
A documentation icon should have been
installed on your workstation’s desktop;
