4.9.2 Instructions
The instructions below detail how to set up the programmer when the Target System is independently
powered from the Target System.
Example:
Here is how to set up the programmer:

1. Create a Programming Project which powers the programmer ‘I/O Level Converters’
2. Connect the Target System to the programmer
The Target System is powered at 3.3V from an ‘Independent Power Supply’.
The programmer ‘Line Driver Circuitry’ must also be powered at 3.3V using the ‘Programmer
controlled Target Power Supply’
The Programmer TVCC and Target System Vcc are not physically connected

Connect the Target System to the programmer via an ISP Cable, Fast Connect connectors
or wire-wrap connectors.
Make sure that the Programmer_Vcc is NOT connected to the Target_Vcc. This may
involve physically cutting the Vcc signal in the ISP cable if you are using one of the ISP
headers to connect to the Target System. This is shown as a virtual link called ‘LK1’ on
the programmer schematic – see section 4.4.
Remove the ‘Vcc Option Link’ on the I/O Connector Module (labelled J6 or J28).
Using a DVM, check that there are no shorts between the Target_Vcc and Target
Ground
In EQTools – Project Builder – Select the <Target Power Supply> tab
Set the required ‘Target Voltage’ and tolerance eg. 3.3V +/- 500mV.
The Voltage ‘Stabilise Time’ should be set to a long enough time to allow the voltage
to reach its final voltage (default: 200ms).
Set the ‘Programmer controlled Power Supply’ to ‘ON’
Converters’ only.
The Target System is NOT powered by this voltage as the Programmer_Vcc and
Target Vcc are physically disconnected.
Leave all other settings as the default values.
This enables the programmer to supply power to the programmer ‘I/O Level
