3.1.1

Connecting to the parallel port

Figure 8.

Parallel port connection between ST Micro Connect box and PC

To connect your emulator to your PC, connect the end of the parallel cable with the ferrite to

the ST Micro Connect’s rear panel 25-pin SUB-D connector (see Figure 8). Connect the

other end of the parallel cable to one of the PC’s parallel ports (LPT1 or LPT2). Be sure to

use the parallel cable provided with your emulator. Using a longer parallel cable may cause

emulator malfunctions. The use of switch boxes between the parallel port connector of your

PC and the emulator is not recommended.

3.1.2

Changing the parallel port set up

Under certain circumstances, you may receive the following error message:

Connection Error (LPT1/LPT2): Interconnection failure. Verify your

input/output cable.

This may mean that the setup of the LPT1 or LPT2 port on your PC is not compatible with

the emulator. To set up the port correctly:

Shut down and restart your PC in order to enter the BIOS setup.

Follow the messages displayed on the screen and when prompted, press the key

required to enter the BIOS setup (usually a function key or the ESC key).

Select the parallel ports menu (this may be listed under I/O ports).

Change the Mode of the LPT port that you have chosen for your ST Micro Connect box

(i.e. either LPT1 or LPT2) to one of the compatible modes listed in Table 1 on page 9.

Save your changes and exit the BIOS setup.
