CHAPTER 1 GENERAL
CHAPTER 1 GENERAL
This chapter describes the outline of the EP-78024.
1.1 Operating Environment
The EP-78024 is a probe set that connects an in-circuit emulator and a target system. By connecting the incircuit emulator and target system with the EP-78024, the debugging environment of a microcontroller is
established and the hardware and software of the target system can be debugged. For details of connection,
refer to CHAPTER 2 CONNECTION.

CHAPTER 1 GENERAL
1.2 Organization
The EP-78024 consists of an emulation probe and a connector board.
(1) Emulation probe
The emulation probe consists of the following three parts:
■ Probe
Connects the in-circuit emulator and target system.
• EP-78024CW-R : 64-pin CW probe
• EP-78024GF-R : 64-pin GF probe
■ Ground clip
Connected to GND of the target system to make the GND potential of the in-circuit emulator the same
as that of the target system and thereby improve the resistance to static electricity and the noise
immunity of the system.
■ External sense clip
Consists of eight sense clips which are used to check the voltage level of the pins of the IC mounted
on the target system.
(2) Connector board
The connector board connects the pins on the emulation board which output signals to the emulation
probe, and is connected to the connectorNote on the emulation board.
Note The location on the emulation board at which the connector board is to be connected differs
depending on the emulation board. Refer to the User’s Manuals of the in-circuit emulator or
emulation board.

CHAPTER 2 CONNECTION
This chapter describes how to connect the EP-78024, turn on/off the power, and remove the emulation probe
from the target system.
2.1 Connecting In-Circuit Emulator and Target System
Connect the in-circuit emulator and target system following these steps:
(1) Connect the emulation board and connector board.
Note that the board to be connected differs depending on the in-circuit emulator used.
(2) Connect the in-circuit emulator and emulation probe.
(3) Connect the emulation probe and target system.
(4) Connect the external sense clip (when the external sense clip is used).
(5) Turn on the power.
Each step, (1) to (5), is described in detail next.
5
CHAPTER 2 CONNECTION
(1) Connecting emulation board and connector board
<1> Turn off the power to the in-circuit emulator.
<2> Connect the emulation board and connector board.
<3> Install the emulation board (with the connector board connected) to the in-circuit emulator.
★
Caution If the connector board is inserted to a wrong connector on the emulation board,
the in-circuit emulator may be damaged.
In the following description, it is assumed that the emulation board IE-78044-R-EM is used.
<1> Turn off the power to the IE-78000-R.
<2> Connect CN3 and CN4 of the connector board to CN3 and CN4 of the IE-78044-R-EM.
<3> Remove the screws (at six places) from the top of the IE-78000-R, and open the lid.
<4> Pull the card pullers at both edges of the IE-78000-R-BK in the in-circuit emulator toward you to pull
out the board.
<5> Secure the IE-78044-R-EM and IE-78000-R-BK with screws.
<6> Return the IE-78000-R-BK, onto which the IE-78044-R-EM has been mounted, to the original position
in the IE-78000-R.

Remark The shape of the emulation board differs depending on the model, but connection between
the emulation board and connector board is the same as shown in Figure 2-1.
For details of how to mount the board to the in-circuit emulator, refer to the User’s Manual
of the in-circuit emulator.

CHAPTER 2 CONNECTION
(2) Connecting in-circuit emulator and emulation probe
<1> Connect the emulation probe to the emulation probe connecting DIN connector on the top of the
in-circuit emulator.
<2> After connection, be sure to secure the emulation probe and in-circuit emulator with screws.

connector to be connected differs depending on the emulation board.
Refer to the User’s Manual of the in-circuit emulator or emulation board.

CHAPTER 2 CONNECTION
(3) Connecting emulation probe and target system
Connect the emulation probe and target system in the following sequence:
Cautions 1.
Before connecting the emulation probe to the target system, be sure to connect
the ground clip first. Otherwise, the in-circuit emulator may be damaged by static
electricity.
2.
Be sure to connect the pins in the correct direction. If they are connected in the
wrong direction, the in-circuit emulator may be damaged.
<1> Turn off the power to the target system.
<2> Solder the conversion socket to the target system. Use the following socket:
• EP-78024CW-R : Shrink DIP socket commercially available
• EP-78024GF-R : Socket supplied as an accessory (EV-9200G-64)
<3> Connect the ground clip of the emulation probe to the ground (GND) of the target system.
<4> Connect the emulation probe to the target system so that the position of the tip of the emulation
probe comes to the position of pin 1 of the conversion socket solder onto the target system in step
<2> above.

CHAPTER 2 CONNECTION
(4) Connecting external sense clip (when external sense clip is used)
★
The emulation probe is provided with an external sense clip that consists of eight clips and can trace the
signals of the hardware on the target system in real time.
Because the external sense clip is directly connected to the input buffer HCT244 in the in-circuit emulator,
its input is TTL level.
Usually, the eight external sense clips are used as input signal lines. Depending on the setting of the OUT
command of the in-circuit emulator, however, the signal line of external sense clip 1 can be used to output
a trigger signal to an external device when an event occurs (for details, refer to the manual of the in-circuit
emulator).
Cautions 1.
Connect the external sense clips to the signal lines of TTL level.
If they are
connected to the other signal lines, the high and low levels of signals cannot be
accurately detected. In addition, the sensors of the in-circuit emulator may be
damaged depending on the voltage level.
2.
★
When using external sense clip 1 as a trigger output line, make sure that external
sense clip 1 is not connected to a signal output line. Otherwise, malfunction may
occur.
10
CHAPTER 2 CONNECTION
Connect the external sense clip in the following sequence:
<1> Turn off the power to the target system and then to the in-circuit emulator.
<2> Mount a commercially available IC clip to the IC on the target system to be traced.
<3> Connect the external sense clip to the IC clip.
<4> Turn on the power to the in-circuit emulator and then to the target system.

Remark To connect the external sense clip, use an IC clip whenever possible, to prevent bad
contact and improve operability.

CHAPTER 2 CONNECTION
2.2 Turning On/Off Power
After connecting the emulation probe and target system, turn on the power. Be sure to turn on or off the power
in the sequence described below.
Caution Be sure to turn on/off the power in the correct sequence; otherwise, the in-circuit
emulator may be damaged.
(1) Power-on sequence
<1> Turn on power to the in-circuit emulator.
<2> Turn on power to the target system.
(2) Power-off sequence
<1> Turn off power to the target system.
<2> Turn off power to the in-circuit emulator.

CHAPTER 2 CONNECTION
2.3 Removing Emulation Probe from Target System
Remove the emulation probe from the target system in the following sequence:
★
(a) With EP-78024CW-R
<1> Turn off power to the target system.
<2> Turn off power to the in-circuit emulator.
<3> Pull up the lever on the shrink DIP socket.
