Eagle TX Series AMOS Based Terminal Server Technical Manual, Rev. 01
The prerequisite for using the Eagle TX Series terminal server is that you already have an AMOS based
network installation using AlphaTCP 1.4A (or later) or AlphaNET 2.4. With the terminal server, you can
install terminals wherever the network reaches. Distance limitations of RS-232 cabling are no longer a
factor. A typical system configuration is shown in Figure 1-2.

The Eagle TX Series is more than just a terminal server, however. It is a powerful AMOS-based
computer in its own right. That means you can run applications there, offloaded from the host CPU. In
fact, MULTI, Alpha Micro’s window based environment manager, is also included in the Eagle TX’s
Flashcard, allowing you to run MULTI remotely and free up the host CPU for other processing needs.
Figure 1-3 shows an Eagle TX Series terminal server configured on a network with two AMOS host
systems, utilizing the built-in MULTI software to switch between the two hosts with a single keystroke,
and Figure 1-4 illustrates various system concepts regarding the Eagle TX interaction with an AMOS
based host computer.
