GENERAL DESCRIPTION
1.2 Configuration
The EP-78230GC-R is a set of a emulation probe and connector board.
(1) Emulation probe
The emulation probe consists of the following:
Probe
Connects in-circuit emulator and target system.
• EP-78230GC-R: 80 pin GC probe
• EP-78230GJ-R: 94 pin GJ probe
• EP-78230LQ-R: 84 pin LQ probe
Ground clip
Is connected to target system GND. In-circuit emulator and target system GND potentials become the
same and resistance to static electricity and noise is provided.
External sense clips
These eight sense clips are used to see the pin levels of ICs mounted on the target system.
(2) Connector board
The connector board is a board used to connect the output pins to the emulation probe on the emulation
board. The connector board is attached to the emulation board connector Note.
Note What the connector board is mounted to depends on the board to be connected. See Table 2-1 of this
manual and refer to the users’ manual of the in-circuit emulator or emulation board.

CHAPTER 2 CONNECTION
This chapter explains the EP-78230GC-R connection method, power on and off sequence, and emulation
probe removal method from the target system.
2.1 Connection of In-circuit Emulator and Target System
The connection procedure is outlined below:
(1) Connection of emulation board and connector board
The type of the board to be connected depends on the in-circuit emulator to be used.
(2) Connection of in-circuit emulator and emulation probe
(3) Connection of emulation probe and target system
(4) External sense clip connection (when external sense clips are used)
(5) Power on
Next, these connection procedures are explained in detail.

CHAPTER 2 CONNECTION
(1)
Connection of connector board
Which board the connector board is connected to depends on the target device.
See Table 2-1 for the type of board to be connected and the CN numbers of each board.
The µPD78234 subseries is taken as an example of the target device to be connected.
Caution
If the connector board is inserted with a wrong connector, the in-circuit emulator may be
broken.
• Connection example of connector board
The connector board is connected to the IE-7823X/22X ADAPTER BOARD which is fixed to emulation board
IE-78230-R-EM.
Insert CN2 and CN3 of the connector board to those of the adapter board in such a way that the pin numbers
coincide. See Figure 2-1.

The shape of the emulation board depends on the type of the pertinent product. The
connection steps to the connector board, however, are the same as shown in Figure 2-1. Refer
to the user’s manual of the individual in-circuit emulators for the details of board mounting

CHAPTER 2 CONNECTION
(2) Connection of in-circuit emulator and emulation probe
The connection procedure is outlined below:
1)
2)
Connect the emulation probe to the emulation probe connection DIN connector on the in-circuit emulator
top.
After connection, be sure to fix the emulation probe and in-circuit emulator with mounting screws.

The Connecting parts may be different, according to the emulation board used.
Refer to the in-circuit emulator or emulation board User’s Manual.
CHAPTER 2
Connection of emulation probe and target system
Connect the emulation probe and target system in the following sequence:
Cautions 1.
2.
Before connecting the probe to the target system, be sure to connect the ground clip first.
If the ground clip is not connected, in-circuit emulator may be destroyed due to static
electricity, etc.
In connection, be careful so as not to insert the pins oppositely. If erroneous connection
is made, in-circuit emulator may be destroyed.
1) Turn of the target system power.
2) Solder the conversion socket (accessory: EV-9200GC-80, EV-9200-94) to the target system. Use a
commercial QFJ socket for the LQ probe.
3) Connect the emulation probe ground clip to the target system ground (GND).
4) Insert the emulation probe so that the tip of the emulation probe main unit couples with pin 1 of the
conversion socket or the socket QFJ soldered on the target system in 2).

CHAPTER 2
CONNECTION
(4) External sense clip connection
The emulation probe has eight external sense clips that can trace the signals on the target system in
realtime.
The external sense clips are directly connected to the input buffer HCT244 installed in the in-circuit
emulator proper, therefore their input levels are TTL levels.The eight external sense clips are usually input
signal lines, but the signal line of the No.1 external sense clip can be used as the trigger output signal line
to the external circuit at the time an event is generated by setting an in-circuit emulator OUT command.
Refer to the in-circuit emulator user’s manual.
Cautions
1.
2.
Connect the external sense clips only to TTL level signal lines. If the external sense clip
is connected to any other signal line than the TTl level, accurate high or low level cannot
be detected. The in-circuit emulator sensor may be destroyed depending on the voltage
level.
When the No.1 external sense clip is used as an external trigger output, be sure it be not
connected to the signal output line. Negligence in this may result in trouble.
11
CHAPTER 2 CONNECTION
To use the external sense clips, connect in the following sequence:
1)
2)
3)
4)
Turn off the target system power and the in-circuit emulator power in order.
Attach a commercially available IC clip to any IC to be traced on the target system.
Connect the external sense clip to the attached IC clip.
Turn on the in-circuit emulator power and the target system power in order.

Remark
12
To connect the external sense clips, preferably use IC clips. Touch mistake can be prevented to
improve operability.
CHAPTER 2
CONNECTION
2.2 Power On and Off Sequence
Upon completion of connection of the emulation probe and target system, next turn on the power. The
power on and off sequence is as follows:
Caution
Be sure to turn on and off the power in the sequence described below. If you turn on and
off the power in erroneous sequence, in-circuit emulator may be destroyed.
(1) Power on sequence
