This chapter describes the hardware connections necessary for configuring the EM1500. This is followed
by an example of telneting to a unit and a quick introduction to the Rabbit Engineering Demo Board.
2.1 Hardware Connections
An Ethernet connection is required for configuration. You may use a browser or the stand-alone configura-
tion program that is included on the CD in the EM1500 Tool Kit.
2.1.1 Ethernet Connection
To make the Ethernet connection, you will need:
• host PC with Ethernet access (i.e., RJ-45 jack)
• Ethernet cross-over cable, or a hub
1
and 2 straight-through cables
2
• power supply

2.1.1.1 Host PC with Ethernet Access
Your PC must have an RJ-45 jack to connect to an Ethernet network. It is an 8-wire connector that looks
similar to the ubiquitous (and slimmer) 6-wire RJ-11 connector used for telephone equipment. If your PC
does not have an RJ-45 jack, you will need to install a 10Base-T or 100Base-T Ethernet card.
Please note that neither the telnet example described in this chapter, nor the configuration process
described later in the manual have need of the EM1500 explicitly knowing the IP address of the host PC.
This is because the EM1500 will not be initiating the Ethernet connection in these 2 cases. This is not to
say that the host PC does not need an IP address—it definitely does. How this is accomplished depends on
the operating system and the network card that is installed on the machine.
2.1.1.2 Using a Cross-Over Cable
An Ethernet cross-over cable can connect the RJ-45 jack on the front panel of the EM1500 directly to the
RJ-45 jack of the host PC. This creates a very small isolated LAN on your desktop.
If you are using this hardware configuration, an IP address will have to be statically assigned to the
EM1500 since it is unlikely there will be DHCP services available.
1. A hub may be purchased in the TCP/IP Tool Kit, which is sold separately.
2. A suitable power supply and the cables needed by the EM1500 for Ethernet connection are supplied in
the EM1500 Tool Kit, which is sold separately. Tool kits sold outside North America do not include a
power supply.
