The CP2201EB can be connected to an Ethernet network using a standard Ethernet cable (see Figure 16) or
directly to a PC using a crossover cable (see Figure 17). Table 2 describes the benefits of using each of the
connection methods. A standard Ethernet cable is included in the kit and crossover cables are available for order
from the Silicon Laboratories website, at
.

Remote access to embedded system.
Distance from PC to embedded system is limited by
the length of the cable.
Multiple embedded systems may be networked and
accessed from the same (or multiple) PC(s).
Only a single embedded system may be accessed
from a single PC.
Shared communication medium. System may experi-
ence packet delays under heavy network traffic. This
effect is greatly reduced if using a switched network.
Dedicated channel bandwidth. Good for achieving
consistent data throughput measurements.
An existing network with wall outlet or a router/switch is
required.
No additional hardware required.
PC does not require any additional IP address configura-
tion.
PC must be configured with a static IP address in
order to recognize embedded system.
Standard cable is included in evaluation kit.
Crossover cable is included in evaluation kit.
