2.2.2 Power Supply from Target System
The BDI2000 needs to be supplied with 5 Volts (max. 1A) via BDI MAIN target connector (Rev. A) or
via TARGET A connector (Rev. B/C). This mode can only be used when the target system runs with
5V and the pin «Vcc Target» is able to deliver a current up to 1A@5V. For pin description and layout
see chapter 2.1 «Connecting the BDI2000 to Target». Insert the enclosed Jumper as shown in figure
below. Please ensure that the jumper is inserted correctly .
For error-free operation, the power supply to the BDI2000 must be between 4.75V and 5.25V DC.
The maximal tolerable supply voltage is 5.25 VDC. Any higher voltage or a wrong polarity
might destroy the electronics.
