3 Connectivity
The ST Micro Connect box provides three possible connections to the host PC: parallel port,
USB and Ethernet. The type of connection that you use will be determined, in part, by the
configuration you choose for your EMU3 emulator.
In the in-circuit communication configuration, you can use either the USB or the parallel
port. Ethernet is not supported in this configuration. In the emulation configuration you can
use the Ethernet, USB or parallel port.
When you start your emulation, in-circuit debugging or in-circuit programming sessions, you
will have to set the connection type in STVD7 or STVP7. In STVD7, set the port in the
Debug Instrument Settings window (Debug Instrument>Target Settings). When
programming your ST7 with STVP7, set the port in the Configuration window
(Configure>Configure ST7 Visual Programmer). For more information refer to your
software's online help.
The following sections provide you with information about supported connections, as well as
how to connect your PC via:
●
Section 3.1 – Parallel port
●
Section 3.2 – USB port

Section 3.3 – Ethernet port
3.1 Parallel port
Your EMU3 emulator supports the parallel port connection modes listed in Table 1 , when
using either the emulation or the in-circuit communication configurations.
