Logic Bus Trigger Setup
The Logic Bus Trigger setup dialog is shown as follows:
The Logic Bus trigger dialog is very similar to the Digital Logic trigger dialog. The main difference
is that you must select a Digital source (Digital1, Digital2, Digital3, or Digital4). In addition, only
those bits that are defined as part of that Digital group can be defined in the Logic Bus setup
dialog. A hexadecimal data value can be entered directly, or read as a result of the binary setup.
Digital Logic Threshold Setup
The Digital Logic Threshold Setup dialogs are located on both the
Trigger
and
Digital Setup
dialogs. It is important to note that a selection made in one location does affect the value in the
other. Four different logic levels can be selected. One level can be set for each of the four groups
D0 to D8, D9 to D17, D18 to D26, and D27 to D35. When connecting your lines, make sure all
lines with like levels are connected to the same set of 9 digital lines.
