Installing the Hardware
The ST7 HDS2 emulator is connected through the parallel port to a PC computer which runs the control software (ST7 Visual Debug) as explained later. To connect your ST7 HDS2 emulator, you will have to follow these general steps:
1
Connect the ST7 HDS2 to your PC using the parallel cable provided.
2
Connect the two flat cables of your ST7 HDS2 emulator to the emulation probe connectors.
3
Connect the ST7MDT5-Active Probe to your application using the protective probe (ref.: DB374).
4
Connect the power supply cable between the power supply block and the power connector located on the rear panel of your ST7-HDS2 emulator.
5
Power up the emulator and then connect your application power supply.

Step 1: Connecting the Emulator to your PC
1
Shutdown and power-off the PC that is to be connected to the emulator.
2
Connect one end of the parallel cable to the emulator’s rear panel 25-pin SUB-
D connector and the other end to one of the PC’s parallel ports (LPT1 to
LPT2)—refer to Figure 4 .
Note:
Centronics (or PC-AT or SPP), ECP and EPP parallel port configurations are supported by the emulator.

Step 2: Connecting the HDS2 and the Probe
1
Ensure that the application and the emulator are powered-off.

Plug the two 50-wire flat cables into J1 and J2 connections on the probe, as described below (refer also to
Figure 5
):

Step 3: Connecting the ST7MDT5-Active Probe to your Application
The emulated MCU is available in two packages—the SDIP32 package and the
SO34 package. Accordingly, there are two possible connection schemes depending on the package you have chosen.
For the SDIP32 package, connect the emulation probe to your application board as follows (refer to Figure 7 ):
1
Connect the ST7MDT5-Active Probe with SDIP32 socket (ref.: DB374)to the protective probe (ref.: DB437).

For the SO34 package, connect the emulation probe to your application board as follows (refer to Figure 8 ):
1
Connect the SO34 socket adapter (ref.: DB354 + DB355) to your application board. If the socket adapter is in two parts (as shown in
Figure 8
), connect
DB355 to your application board, then carefully insert the male connector of the
DB354 into the top of DB355.
2
Connect the ST7MDT5-Active Probe with SDIP32 socket (ref.: DB374)to the protective probe (ref.: DB437).

Step 4: Connecting the emulator power supply
Warning: Make sure that both the ST7MDT5-EMU2B and the application are OFF before making any connections.
1
Connect the external power supply provided with the emulator to the rear panel of the mainframe using a 5-pin DIN connector.
2
Plug the power supply into the mains using the supply cable provided.
Mains voltage specifications
AC voltage:
Frequency:
100 V to 240 V
50 to 60 Hz
Step 5: Powering up
1
Check the ST7-HDS2 operating voltage (110 V/220 V) indicated on the label on the power supply. Contact your dealer if this voltage does not correspond to your mains’ power supply.
2
Power up the ST7-HDS2 from the ON/OFF switch located on the rear panel.
The LED labelled Power on the front panel should then light up.
3
Power up your application.
