E30A Emulator User's Manual
2.6.2 Using the Coaxial Converter Board R0E00030ACKZ00
(1) Processing NSD pin
Pull up NSD pin of the target MCU to Vcc1 with a 4.7kΩ resistor. (It cannot be connected directly to Vcc1 and Vcc2.)
Furthermore, be sure that the wiring from NSD pin to the connector is shortest possible.
(2) Mounting part in place
Mount the 2.54mm pitch 3-pin socket included with the product (PIC-FS03-G+R made by Honda Tsushin Kogyo) on
designated position of the user system.
(3) Connection procedure
Plug the 50Ω coaxial cable included with the product (gray) into the E30A emulator and CN1 on coaxial converter board.
Fit CN2 on coaxial converter board into the 3-pin socket on user system. It can be turned 180 degrees as it is fitted into
place.
Although the cable can be easily removed/inserted and can be connected over a distance, the power supply condition of the
user system cannot be monitored. Furthermore, since only a software reset is possible from the E30A emulator, a hardware
reset is required when the emulator debugger is started or when a communication error occurs. Figure 2.5 is a connection
diagram showing how to connect the E30A emulator and user system using the coaxial converter board.
