2.2 Connecting the BDI2000 to Power Supply

2.2.1 External Power Supply

The BDI2000 needs to be supplied with 5 Volts (max. 1A) via the BDI OPTION connector (Rev. A)
or via POWER connector (Rev. B/C). The available power supply from Abatron (option) or the en-
closed power cable can be directly connected. In order to ensure reliable operation of the BDI2000,
keep the power supply cable as short as possible.

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.

Please switch on the system in the following sequence:

• 1 --> external power supply

• 2 --> target system
