4. Connect Daughter Board To The Sensor Board (EVKT-KNOB or TBMA)

Use the provided ribbon cable to connect the connector board to the sensor board.

The EVKT-KNOB comes with a pre-soldered female socket connector, while TBMA boards do not. The

TBMA boards require the female connectors to be hand soldered in order to be used with the EVKT-

MACOM. Before soldering, place the connector polarization slot next to pin 1 (see Figure 15).

On the TBMA boards (RD and LT), the CN1 connector must be connected to the TBMA-CONN CN1

connector using one of the two provided ribbon cable with 8 conductors (see Figure 16 and Figure 17).

The CN2 connection is not required for SPI communication but provides easy access to the MagAlpha

output signals on the LPC-Link2 daughter board.
