3.3 Mounting an MCU into the Adapter
As this product uses an IC socket for 54-pin shrink DIP, mount the MCU into the IC socket with the
No. 1 pin of the MCU matched to the No. 2 pin of the IC socket on the PCA7400 (SET BOTTOM).
Be careful when inserting the MCU because incorrect insertion can cause fatal
damage to the MCU.
CAUTION
Caution to Be Taken for Handling MCU:
• Do not touch the connector in the IC socket and the pins on the PROM programmer
connector. Otherwise it can cause an electrical insulation failure because of dirt.
When not using, attach the connector pins of this product to the conductive sponge
as it was shipped from the factory.
