HARDWARE PREPARATION AND INSTALLATION
2.6.2 Terminal – EVBU Interconnection
Interconnection of an RS-232C compatible terminal to the EVBU is accomplished via a user-
supplied cable assembly as shown in Figure 2-5. Connect one end of the cable assembly to
EVBU connector P2 (shown in Figure 2-4). Connect the other end of the cable assembly to the
user-supplied terminal/host computer. Refer to Chapter 6 for connector pin assignments and
signal descriptions of EVBU terminal port connector P2.
For those using an IBM-PC or Apple Macintosh personal computer (PC), use a Hayes-
compatible-modem cable to connect the PC to EVBU terminal port connector P2.
Figure 2-5 illustrates a suitable cable assembly for connecting the EVBU to a dumb terminal.
This cable assembly is made from standard mass termination ribbon cable components.
