chapter 2 connections EP-753208GT-R, the sequence for switching on the power and switching it off and the method used to disconnect the emulation probe from the emulation system. 2.1 connection to the ie-75001-r and target system the connection procedure is outlined as follows. (1) connection of the ie-75300-r-em and adaptor board (2) connecting the ie-75001-r and the emulation probe (3) connecting the emulation probe and target system (4) connecting the external sense clip (if the external sense clip is used) (5) switching on the power next, details of each item in the connection procedure are explained. (1) connecting the ie-75300-r-em and adaptor board connect the adaptor board to the ie-75300-r-em. <1> while placing a spacer between the ie-75300-r-em and the adaptor board, connect connectors cn1 to cn4 of the ie-75300-r-em to connectors cn1 to cn4 of the adaptor board. <2> fasten the spacer between the ie-75300-r-em and the adaptor board using the spacer installation screws. <3> first, switch off the ie-75001-rs power. <4> take out the 6 screws in the top of the ie-75001-r unit, then open the units top cover. <5> pull the card pullers on both ends of the board forward and pull out the ie-75000-r-bk note . <6> screw the ie-75300-r-em to the ie-75000-r-bk together. <7> return the ie-75000-r-bk 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 ie-75000-r-bk are installed screw together. therefore, pull out the ie-75000-r-bk from the main unit in above steps <3> ? <4> ? <5>, screw off and remove the ie-75000-r-em before following steps <1> ? <2> ? <6> ? <7>. 5

7 chapter 2 connections (3) connecting the emulation probe and target system connect the emulation probe to the target system by the following procedure. cautions1. before connecting the emulation probe to the target system, be sure to connect the ground clip. if the ground clip is not connected, the ie-75001-r could be damaged by static electricity, etc. 2. when making connections, be careful not to reverse the pins. if connections are incorrect, it could damage the ie-75001-r. <1> switch off the target systems power supply. <2> solder the flexible board (ev-9500gt-48) to the target system. figure 2-3. flexible board <3> connect the emulation probes ground clip to the ground (gnd) pin of the target system. <4> insert into the emulation probe connector under the solder-plated surface of the flexible board soldered on the target system in step <2> in the emulation probe main unit edge connector. back front
8 chapter 2 connections figure 2-4. emulation probe connection (4) connecting the 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 are ttl level inputs. the 8 external sense clips are normally input signal lines. however, by setting the in-circuit emulator out command, the signal line of external sense clip 1 can be used as an outgoing 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. if it is connected to a signal line other than a ttl level signal line, it will not detect the high level and low level accurately. also, depending on the voltage level, the ie-75001-rs 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. if it is connected, a fault may result. connect the external sense clip by the following procedure if it is used. <1> switch off the power to the target system, then the ie-75001-r. <2> install the ic clip (commercially available) on the ic in the target system which is to be traced. <3> connect the external sense clip to the ic clip. <4> switch on the power to the ie-75001-r, then the target system.
9 chapter 2 connections figure 2-5. connecting the external sense clip ic ic clip tar g et system external sense clip remark if an external sense clip is connected, be sure to use an ic clip if at all possible. thishelps prevent faulty contact and improves operability. 2.2 power on and off sequence after connection of the emulation probe to the target system has been completed, switch on the power. the sequence for switching on the power and switching it off is shown below. caution be sure to follow the correct sequence for switching the power on and off. if the sequence is mistaken, the ie-75001-r could be damaged. (1) if the ie-75001-r is connected to the target system ? power on sequence <1> switch on the power to the ie-75001-r. <2> switch on the power to the target system. ? power off sequence <1> switch off the power to the target system. <2> switch off the power to the ie-75001-r.
10 chapter 2 connections 2.3 disconnecting the emulation probe from the target system disconnect the emulation probe from the target system by the following procedure. <1> switch off the power to the target system. <2> switch off the power to the ie-75001-r. <3> pull the flexible board from the connector on the end of the emulation probe. figure 2-6. disconnecting the emulation probe
