This chapter describes how to use two external buttons to control the Flash-Programmer

In order to integrate the Yokogawa Flash-Programmer in an automatic assembly line, two

external switch-buttons or relays connected to EXT.KEX can be used to start a command

sequencer.

A command sequence file (*.CSB) is used to define the function.

In case that the signal lines OAK1+ and OAK1- respectively OAK2+ and OAK2- are shortcut

the command sequence LK1 respectively LK2, stored in the CSB-file, is started.

Alternatively two buttons of the keypad can be used, see

This text file consists of two lines. It can be easily edited, e.g.:

my.csb:

LK1,04,E,B,P,R;remark: Erase/BlankCheck/Program/Verify [

LK2,01,P;remark: only Program without erasing the chip [

Number of commands

Note: A maximum number of 16 commands can be executed within one sequence.
