CHAPTER 2 CONNECTIONS
CHAPTER 2 CONNECTIONS
This chapter explains the procedures for connecting the EP-753304DU-R, switching on/off its power, and
disconnecting the emulation probe from the target system of the EP-753304DU-R.
2.1 Connection of IE-75001-R and Target System
The connection procedure is outlined as follows.
(1) Connecting the IE-75300-R-EM and the adapter board
(2) Connecting the IE-75001-R and the emulation probe
(3) Connecting the emulation probe and the target system
(4) Connecting the external sense clips (if external sense clips are used)
(5) Switching on the power
Next, the details of each item in the connection procedure are explained.

CHAPTER 2 CONNECTIONS
(1) Connecting IE-75300-R-EM and adapter board
Connect the adapter board to the IE-75300-R-EM.
<1> While placing a spacer between the IE-75300-R-EM and the adapter board, connect the connectors
CN1 to CN4 of the IE-75300-R-EM and the connectors CN1 to CN4 of the adapter board.
<2> Fasten the spacer between the IE-75300-R-EM and the adapter board using the spacer installation
screws.
<3> Switch off the power of the IE-75001-R.
<4> Take off the 6 screws on the top of the IE-75001-R unit, then open the unit’s top cover.
<5> Pull the card pullers on both ends of the board forward and pull out the IE-75000-R-BKNote.
<6> Screw the IE-75300-R-EM to the IE-75000-R-BK together.
<7> Replace the IE-75000-R-BK screwed together with the IE-75300-R-EM to the original position of
the IE-75001-R.
Note In the case of the IE-75000-R, the IE-75000-R-EM and the IE-75000-R-BK are installed screwed
together. Therefore, pull out the IE-75000-R-BK from the main unit in the above sequence
<3>→<4>→<5>, remove the screws and pull off the IE-75000-R-EM before following steps
<1>→<2>→<6>→<7>.

(2) Connecting IE-75001-R and emulation probe
<1> Connect the emulation probe to the emulation probe DIN connector (CN5 of the adapter board) on the
top of the IE-75001-R.
<2> After connection, be sure to fasten the emulation probe to the IE-75001-R with the installation screws
provided.

CHAPTER 2 CONNECTIONS
(3) Connecting emulation probe and target system
Connect the emulation probe to the target system by the following procedure.
Cautions 1. Before connecting the emulation probe to the target system, be sure to connect the
ground clip first. Otherwise, the IE-75001-R could be damaged by static electricity, etc.
2. Whenmakingconnections,becarefulnottoreversethepins.Ifconnectionsareincorrect,
this could damage the IE-75001-R.
<1> Switch off the power of the target system.
<2> Solder the shrink DIP socket to the target system.
<3> Connect the emulation probe’s ground clip to the ground (GND) pin of the target system.
<4> Align the No. 1 pin of the 42-pin shrink DIP at the end of the emulation probe with that of the shrink
DIP socket of <2> soldered into the target system, then insert the emulation probe.

CHAPTER 2 CONNECTIONS
(4) Connecting external sense clip
The emulation probe is provided with 8 external sense clips which can trace hardware signals on the target
system in real time.
Since the external sense clips are directly connected to the input buffer HCT244 inside the in-circuit emulator
unit, they have TTL level inputs.
The 8 external sense clips are normally input signal lines. However, by setting the OUT command on the
in-circuit emulator, the signal line of external sense clip 1 can be used as an external trigger output signal line
in the case of an event (see the in-circuit emulator manual for details).
Cautions 1. Connect the external sense clip to a TTL level signal line only. Otherwise, it will not
detect the high level and low level accurately. Also, depending on the voltage level,
the IE-75001-R’s sensor could be damaged.
2. Before using external sense clip 1 as an external trigger output, ensure that external
sense clip 1 is not connected to the signal output line, otherwise a fault may result.

10
CHAPTER 2 CONNECTIONS
Connect the external sense clip by the following procedure if it is used.
<1> Switch off the power of the target system first, then that of the IE-75001-R.
<2> Install the IC clip (commercially available) on the IC which is to be traced in the target system.
<3> Connect the external sense clip to the IC clip installed.
<4> Switch on the power to the IE-75001-R first, then that of the target system.

CHAPTER 3 SETTING MASK OPTIONS
CHAPTER 3 SETTING PORT 3
The DP1 switch on the adapter board is for the port 3 setting. When these switches are ON, pull-up resistors
Note 1
(47 kΩ) or pull-down resistorsNote 2 (47 kΩ) are connected.
At shipping, the DP1 switches are set in the OFF position.
Notes 1. P33
2. P30 to P32
Caution Regarding port 3, the setting method for the adapter board and devices differs.
The pull-up resistor and the pull-down resistor are set by the DP1 switch.
