Figure 2-6. GND Wire
<3> Connect the YQ connector and the exchange adapter to the target connector (D in Figure 2-6).
<4> Connect the emulation probe to the exchange adapter (connection of E to F in Figure 2-6).
<5> Connect the two GND wires on the target system side of the emulation probe to the target system
GND. If a pin or screw is fastened to the target system GND, remove the transparent terminal
cover on the end of the GND wire and fasten the Y terminal of the GND wire to the target system
(G in Figure 2-6). If the GND on the target system is an exposed pad, likewise fasten the Y
terminal to the pad on the target system by soldering (H in Figure 2-6)
(recommended soldering iron temperature setting: 300°C).
<6> If the target system has only one GND, connect only one of the GND wires of the emulation probe.
Cut off the other GND wires with a nipper or leave it as is without removing the pin cover.
<7> Since the length of the GND wire below the head (insulated part) is approximately 60 mm, there
must be at least a GND to which it can be connected to within the range of the two approximately
60 mm radius sections of the target system for connecting the emulation probe, as shown in
Figure 2-7. The GND wire of the emulation probe is soldered to positions J and K in Figure 2-7.
