WHOLE PROGRAMMING TROUBLESHOOTING PROCEDURE
GENERAL PROSTART II TEST POINTS
The following procedure determines whether or not the Prostart is properly functioning.
During the erasing mode (the first 2 seconds), you can check the voltage (multimeter) on the pin 19 TEST/VPP
of the programming connector. Your voltage should be equal to ~11.6 V.
You can check the voltage on VReg too (dependent on the socket). This voltage must be between 1.7 volt and
2.4 volt. If it's not, this is either related to a faulty chip, a badly connected Vreg capacitor or at the start, the chip
was badly inserted.
During the program mode, the consumption has to be about 550mA. If it’s not then again it may be due to a
faulty component.
At the power on the power LED must be on and the LEDS prog and ISD must blink shortly. If that is not the
case please check your power supply (regulated 9VDC an the polarity (GND outside)), then check if the current
is not limited by the power supply.
There are 4 different voltages on the ProStart II
