HARDWARE INSTALLATION

Before installing the hardware, refer to Figure 2-1 provides a diagram for connecting the emulator to your PC
and power supply; Figure 2–2 shows the jumper locations on the board.

NOTE: Proper functioning of the emulator depends upon proper installation and running of the GUI

software on your PC.

Quick Installation Procedure

This section provides the quick method of installing the hardware utilizing a VDC wall-adaptor power supply.

1. If you are using an optional laboratory power supply (not included), turn the power supply ON (before
connecting to the emulator), adjust it to 9.0V, and set it to at least 0.5A; or, plug the supplied wall trans­former into a 120 VAC, 15 amp outlet.

2. Connect the RS-232C serial cable between the emulator and the PC.

3. If you are doing in-circuit emulation, connect the emulator to your design (if it is ready to test).

4. Set up the oscillator and option jumpers.

5. Refer to the “Electrical Safeguards” page of this manual.

6. Connect the power supply or wall transformer to the emulator.

Serial Cable Connection

Locate the serial cable. Connect the male end to the female connector, and the female end to the COM1,
COM2, COM3, or COM4 connector of your PC.

Complete Hardware Installation

Connecting to a Power Supply

If your power supply allows voltage adjustment, do the following:

1. Turn the power supply on and adjust it to +9V.

2. Set the power supply for at least 0.5A, if there is a current-limiting adjustment.

3. Turn the supply OFF or ensure that a nonadjustable supply is OFF.

4. Locate the power connectors on the emulator. Connect the connector labeled GND on the emulator to
your power supply connector that’s labeled COM, GND, or with a ground symbol. Connect the connector
labeled 9 VDC on the emulator to your power supply connector that’s labeled “+” or “+V”.

Connecting the Serial Cable to the PC

5. Connect the male end of an RS-232C serial cable to the female connector on the emulator, and the female
end of the serial cable to the COM1, COM2, COM3, or COM4 connector of your PC.

NOTE: If connector availability is limited to a 25-pin COM1 through COM4, you’ll have to use either a

different cable or a 25-pin to 9-pin converter. (ZiLOG does not provide either of these items.)

Connecting to Your Design

6. Locate the emulation cable for your Z8

NOTE: Wear a properly grounded wrist strap or similar ESD protection before proceeding with this step.

7. Plug one end of the emulator cable into the Z8

target board. Plug the other end of the cable into the matching black emulation cable connector in front
of the emulator (see Figure 2-2).

NOTE: The inductance and capacitance of the emulation cable may affect the signals to and from the

emulator and target board, especially if the target board has low-current drivers, pull-ups, and pull­downs.

Setting Up the Z8ICE000ZEM Oscillator and Option Jumpers

The oscillator and option jumpers are accessible on the emulator. Refer to Figure 2-2 for emulator jumper
locations. Refer to Table 2-1 and Table 2-2 when setting up the jumpers. Also refer to Appendix C for the
complete Z8ICE000ZEM Emulator Schematic Diagram.

The option jumpers allow you to configure things like whether the emulator provides power to your design
on the VCC pin of the emulated Z8

PLUS

device, and how the clock pin is connected.

The clock for the emulated device can be provided from an oscillator in the emulator or from a TTL-level
clock on your design. For electrical reasons, the clock cannot be supplied from the oscillator on your design
until you are done using the ICEBOX and have either programmed an EPROM or OTP Z8

PLUS

and installed

it in your design.

WARNING!

If your design already has a power supply, do not power your design from the emulator VCC pin on loca­tion JP1 of the Z8M001 board.

Power Up

If anything unusual (such as unexpected sounds and smells) occurs the first time you turn on the power
supply, quickly turn off the power supply and check your connections. If your power supply allows voltage
adjustment, ensure that adjustment is within specified range (see “Hardware Specifications” section). If your
power supply has a current meter, ensure that the emulator is drawing within the rated current.

After emulator power-up, press the MASTER RESET button to reset the emulator. (Pressing the TARGET
RESET button resets only the Z8M001 ICE chip.) If the emulator is not powering your design through the
VCC pin, turn on the power supply of the design.

Power Down

When powering down, follow the procedure described below:

1. Press the TARGET RESET button on the emulator.

2. Power down the target application board (if using its own power supply).

3. Remove the target pod.

4. Power down the emulator.
