1.1 Power Up/Down Instructions
This section of the document describes how to connect power supply for
different cases in order to avoid mistake during measurements.
1.1.1 Power Supply Connection
Connect 5-14V DC power to the “+IN and “-IN”” connectors (see Fig 1.1).
Fig 1.1 Connect 5-14V to either of the “+IN”and “-IN” DC power connectors located in
both ends of the board (see blue rectangles).
Fig 1.2 shows the RC switch in “On” position.
Fig 1.2 the RC switch in “On” position.

1.2.1 Power-up instruction:
- Mount the BMR:s in the desired positions
- Connect and turn On the 5-14 V supply
- Turn RC switch in On position
▪
The LEDs should now give green light, (unless the
outputs of the BMRs are not configured to be disabled).
- Connect the PMBus Adapter/Cable to the board.
- Start the software program.
1.2.2 Power-down instruction:
- Turn RC switch in Off position or turn Off the 5-14V Supply
- Now, the BMR modules can be removed/replaced.

1.3 Board to board connectors
Fig 1.4 shows the board to board connectors
The following signals are connected to the board to board connectors:
SYNC
SALERT
SCL
SDA
CTRL
GND
This board can be connected to other 3E evaluation boards through the board
to board connectors. All interconnected boards are sharing the same PMBus
and SYNC signals and only one PMBus to USB adapter is needed.
Note: When the switch SW1 (see fig 1.2) is in On position the CTRL_ALL pin
on each module is connected to CTRL which is connected to the board to
board connectors.

2 Address and vout range resistors
This section describes the locations of the Address and Vout-range pinstrap
resistors, see table 1 for the resistors for each POL position. To know what
resistor value to mount, please look in the actual technical specification of the
BMR product.
Fig 2.1 shows the positions of the address and vout range resistors.

3 Modification for Parallel Operation
It is possible to operate two or three BMR 463 2002 or two or three BMR 464
2002 in parallel by connecting the output voltage connectors together.
For proper performance the connection shall be of low impedance and the
point of connection shall be at the PCB as indicated in Figure 3.1.
As connection power jumpers can be used as shown in Figure 3.2. Note that
the power jumpers shall be attached below the ring nuts of the output voltage
connectors. Alternatively the connection can be made of a piece of thick
copper wire that is soldered directly to the PCB.
