FS2003 ISP Programmer - User Guide V1.07 – 1
•
The Target System can supply power to
the programmer as long as the Target
Voltage is 3.0 – 5.0V.
•
The Target System must be able to
supply the worst case programming
current to the programmer (approx
60mA).
•
Fit the Jumper J9 which connects the
Target Vcc (3.0 – 5.0V) on the ISP
Header connectors to the Programmer
Vcc rail.
•
The programmer will automatically boost
the Target Vcc supply up to +5.0V if it is
less than 5.0V.
•
The programmer is powered from +9.0 to
12.0V via the DC power input (CON1) on
the rear panel of the programmer.
•
The Target System is powered from an
independent power supply.
•
The Jumper J9 must NOT be fitted.
This disconnects the Target Vcc from the
Programmer +5V Vcc.
•
The 'Target Vcc' signal must still be
connected to the 'Programmer Vcc'
signal on the ISP Header as this voltage
is used to power the 'I/O Level
Convertor'.
