Introduction
The PoE-VOICE-EB can be connected to an Ethernet network using a standard Ethernet cable (see Figure 19) or
directly to a PC using a crossover cable (see Figure 20). Table 4 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 www.silabs.com. Both cable types are included in the reference design kit.

Remote access to embedded system.
Multiple embedded systems may be networked and
accessed from the same (or multiple) PC(s).
Shared communication medium. System may experience
packet delays under heavy network traffic. This effect is
greatly reduced if using a switched network.
An existing network with wall outlet or a router/switch is
required.
PC does not require any additional IP address configura-
tion.
Standard cable is included in evaluation kit.

Or
Distance from PC to embedded system is limited by
the length of the cable.
Only a single embedded system may be accessed
from a single PC.
Dedicated channel bandwidth. Good for achieving
consistent data throughput measurements.
No additional hardware required.
PC must be configured with a static IP address in
order to recognize embedded system.
Crossover cable is included in evaluation kit.
