Running Dynamic C Via Ethernet Cables; Run A Sample Program - Rabbit RCM3365 User Manual

2.3.2 Running Dynamic C via Ethernet Cables

The firmware needed to run RabbitSys has been preloaded on RCM3365 RabbitCore
modules sold for use with Dynamic C RabbitSys. The software from the Dynamic C and
the Dynamic C RabbitSys CDs must be installed on your PC. A system running RabbitSys
can be connected to a DHCP network using straight-through Ethernet cables, or it can be
connected directly to the PC via an Ethernet crossover cable.
• If you are connecting to a network with a DHCP server, use a CAT 5/6 straight-through
Ethernet cable to connect the PC or workstation to the network, and connect the
Ethernet jack on the RCM3365 to the network using a second CAT 5/6 straight-through
Ethernet cable.
• If your PC or workstation is running a DHCP server, connect the CAT 5/6 Ethernet
crossover cable from the PC or workstation directly to the Ethernet jack on the
RCM3365. Follow the instructions below for a straight-through Ethernet cable.
TIP: It is recommended that you use one of the above options for a PC/workstation or
network with a DHCP server or the serial cable programming option when you are
using the RCM3365 for the first time since these options are easier to set up and run.
• If your PC/workstation does not have a DHCP server, you will have to enter the TCP/IP
parameters into the RCM3365 module and on to the PC, notebook, or workstation. See
Appendix E for more information on this option.

mode" from the Dynamic C
Before you compile and run a program via the Ethernet for the first time via a DHCP net-
work, you must run the rdiscover utility by double-clicking it on your PC desktop. Your
PC must be connected to the same DHCP network as the RCM3365. The utility will open a
window and list the MAC addresses for any RabbitSys boards connected to the network.
Select a board from the list to display additional information such as the board's Internet
address. This is the IP address to enter when you access the Dynamic C
