(2) Connector J4
To use the external trigger signal as event input of trigger breaks or trace points, connect the 2-
wire external trigger signal cable included with your M34514T-MCU board to the connector J4.
Connect the black clip of the external trigger cable to GND, and use the white clip for external
trigger signal input. Table 4.6 lists the pin assignments of the connector J4.

(3) Connector J6
The connector J6 is a connector used to connect an oscillator circuit board OSC-2. Table 4.7 lists
the pin assignments of the connector J6. Figure 4.6 shows the pin layout of the connector J6. For
the 4.19 MHz operation with the oscillator circuit board OSC-2, see Figure 4.7.
