Wiring instructions for programming the microcontrollers on the Handheld Reader PCB
Notes:
-
To program microcontroller C, D and E on the Handheld Reader, you must go to the respective J connector for that controller.
-
J101 is for microcontroller C, J102 is for microcontroller D, and J103 is for microcontroller E
-
Solder the wires from the 5-pin adaptor connector to the correct J connector of the microcontroller you wish to program.
-
Use a female 5-pin connector for programming the Handheld Reader
