Chapter 1. Precautions for Safety In both the user's manual and on the product itself, several icons are used to insure proper handling of this product and also to prevent injuries to you or other persons, or damage to your properties. This chapter describes the precautions which should be taken in order to use this product safely and properly. Be sure to read this chapter before using this product.
WARNING Warnings for Use Environment: • This equipment is to be used in an environment with a maximum ambient temperature of 35˚C. Care should be taken that this temperature is not exceeded. • Select the proper programming mode of the PROM programmer. CAUTION Cautions to Be Taken for Modifying This Product: • Do not disassemble or modify this product. Disassembling and modifying the product will void your warranty. Cautions to Be Taken for This Product: • Use caution when handling this product.
Chapter 2. Introduction This product is a PROM programming adapter for 7200 Series MCUs (8-bit MCU). This product is used to write programs into the internal ROM of MCU with a commercially available PROM programmer. This manual mainly explains specifications of this product and how to operate it. Figure 2.1 shows the external view of the product and its constituent parts. IC59-4206-G4 IC socket (made by Yamaichi ElectronicsCo., Ltd.) 408 A7 PC R1 R2 RE V.
Chapter 3. How to Write the Program This chapter describes procedures you need to follow to write the program. For details on how to operate the PROM programmer, refer to the user's manual of the PROM programmer. 3.1 Programming Procedure Follow the steps (1) to (7) below to write the program into the MCU. (1) Read the program into the PROM programmer. (2) Attach the adapter to the IC socket of the PROM programmer. (See Section 3.2) (3) Insert the MCU into the adapter. (See Section 3.
3.2 Attaching the Adapter to the PROM Programmer As shown in Figure 3.1, attach the No. 1 pin of the PCA7402E connector (standard-pitch 32-pin pinheader mounted) to the No. 1 pin of the IC socket of the PROM programmer. Be careful when attaching to the PROM programmer because incorrect insertion can cause fatal damage to the MCU.

3.3 Inserting an MCU into the Adapter As shown in Figure 3.2, insert the MCU into the IC socket with the No. 1 pin of the MCU matched to the No. 1 pin of the IC socket on the PCA7408. Be careful when attaching to the PROM programmer because incorrect insertion can cause fatal damage to the MCU.

Chapter 5. Troubleshooting The tables below summarizes errors to be checked carefully before you determine them to be a fault. 5.
5.2 MCUs Do Not Function Normally The program operates normally on the emulator, but when the MCU that has normally been written is attached the same program does not function normally. (1) Is the offset address specified correctly when copying data into the PROM programmer? (2) In the emulator, NOPs are often inserted in the area where the program has not been read, therefore the program happens to appear functioning normally even though it may have gone wild. Check your program again.
