CHAPTER 4 SETTING CLOCK
4.3.2 To use an external clock
As a factory-set condition for shipment, a component block wired as shown in Fig. 4-15 is connected to the X2 (SUB)
socket on the IE-78044-R-EM. If the wiring of this component block remains the same as the factory-set condition, no
hardware adjustments are necessary. However, if the user prepares a component block because another clock source
is to be used, or because the wired component block has been lost, make all connections in accordance with the
procedure described below.
No special setting has to be made on the screen debugger.
Prerequisites
• Component block (IE-78000-R accessory)
• Lead wires
• Soldering tools
Procedure
①
Wire and solder the leads to the component block as shown below.
