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.
