ST7-EMU3 series emulator

Emulation configuration

19/39

4.3.3

Power supply

The power supply for your emulator connects to the rear panel of the ST7 Micro Connect

box (see Figure 18). When you connect the power supply be sure to:

Ensure that the operating voltage (110 Volts/220 Volts), which is indicated on the label

on the power supply, matches your mains supply. Contact your dealer if this voltage

does not correspond to your mains supply.

Connect the external power supply provided with the emulator to the rear panel of the

ST Micro Connect box using the 5-pin DIN connector.

Plug the power supply into the mains using the supply cable provided.

AC voltage: 100 V to 240 V

Frequency: 50 to 60 Hz

Output and Input triggers

Your ST Micro Connect box has two output triggers (OUT1, OUT2), and one input trigger

(IN), which are available via SUB-click connectors located on the front panel (see

Figure 17). Both input and output signals are at TTL level.

Advanced Breakpoints in STVD7, allow you to define an event based on input signals (see

also Section 4.4.3 on page 22), and program signals to the output triggers.

The following trigger output modes (schematically represented in Figure 20) are supported:

●

Output a pulse—where a signal of value 1 is sent during exactly one memory cycle.

●

Toggle—where the signal value is changed from 0 to 1 or from 1 to 0.

●

Set the output high —where the output signal is set equal to 1.

●

Set the output low—where the output signal is set equal to 0.

Several examples of how to program Advanced Breakpoints to control the sending of signals

to the output triggers are given in STVD7’s online help and user manual.
