HARDWARE PREPARATION AND INSTALLATION
2.4.2
Terminal - EVB Interconnection
Interconnection of an RS-232C compatible terminal to the EVB is accomplished via a user
supplied 20 or 25 conductor flat ribbon cable assembly as shown in Figure 2-2. One end of the
cable assembly is connected to the EVB connector P2 (shown below). The other end of the cable
assembly is connected to the user supplied terminal. For connector pin assignments and signal
descriptions of the EVB terminal port connector P2, refer to Chapter 6.
A dumb terminal or personal computer is always connected to the
terminal I/O port but it is very common not to have any external
equipment connected to the host I/O port.
