Note that you can only designate a specific line for your signal event if you’ve
selected Normal in the Type field; if you select High-Speed, the Line field
disappears. Note also that you can only specify a Boolean operator in the
Combination field if you have defined two (or more) output signal components;
if you have less than two output signal components defined, the Combination
field disappears.
Table 3–1 shows the number and type of signal event resources available with
different modules.
Table 3–1: Signal Event Resources
Module Input Output
92A16 Two normal and one high-speed Two normal and one high-speed
92A60 or 92A90 Three normal Three normal
92A96 or 92C96 Two normal or high-speed Two normal or high-speed
92S16 One normal or high-speed One normal or high-speed
92S32 None None
In interaction between any two modules, only one module can drive a high-speed
signal event; the other can only receive it. Using Normal signal events, any
number of modules can drive or receive signal events.
To use high-speed signals, there cannot be any empty slots between the modules
for which signals are defined.
If you have an 92C02 GPIB/Expansion Module in your mainframe, the
Components field appears, allowing you to designate external as well as internal
signal components.
Figure 3–5 shows an example of the Signal Definition overlay.
