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.
