8 chapter 2 connection (2) connection of in-circuit emulator and emulation probe the connection procedure is outlined below: 1) connect the emulation probe to the emulation probe connection din connector on the in-circuit emulator top. 2) after connection, be sure to fix the emulation probe and in-circuit emulator with mounting screws. figure 2-2. connection of in-circuit emulator main unit and emulation probe example note the connecting parts may be different, according to the emulation board used. refer to the in-circuit emulator or emulation board users manual. nec mounting screws emulation probe in-circuit emulator (cnn) note
9 chapter 2 connection (3) connection of emulation probe and target system connect the emulation probe and target system in the following sequence: cautions 1. 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. 2. 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). figure 2-3. connection of ep-78230gc-r and target system nec 1 cut off in-circuit emulator external sense clips ground clip 80-pin gj conversion socket (ev-9200gc-80) target system 1 80 61 60 41 40 21 20

11 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 users manual. cautions 1. 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. 2. 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.
12 chapter 2 connection to use the external sense clips, connect in the following sequence: 1) turn off the target system power and the in-circuit emulator power in order. 2) attach a commercially available ic clip to any ic to be traced on the target system. 3) connect the external sense clip to the attached ic clip. 4) turn on the in-circuit emulator power and the target system power in order. figure 2-6. external sense clip connection ic external sense clip ic clip target system remark to connect the external sense clips, preferably use ic clips. touch mistake can be prevented to improve operability.
13 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 1) turn on the in-circuit emulator power. 2) turn on the target system power. (2) turn off sequence 1) turn off the target system power. 2) turn off the in-circuit emulator power.
14 chapter 2 connection 2.3 removal of emulation probe from target system remove the emulation probe from the target system in the following sequence: (a) ep-78230gc-r and EP-78230GJ-R 1) turn off the target system power. 2) turn off the in-circuit emulator power. 3) pull the metal snap at the emulation probe tip just above and draw out the emulation probe from the conversion socket. figure 2-7. removal of EP-78230GJ-R remark remove the ep-78230gc-r in the same way as shown in figure 2-7. conversion socket target system metal snap
15 chapter 2 connection (b) ep-78230lq-r 1) turn off the target system power. 2) turn off the in-circuit emulator power. 3) insert a screw driver etc. between the qjf socket and the metal snap provided at the tip of the emulation probe. pull it down to remove the emulation probe from the qfj socket. figure 2-8. removal of ep-78230lq-r target system qfj socket driver metal snap
