The DLP Dual DLPC900 EVM requires a DMD EVM listed in Section 2.2.

• The flex cables provided with the DMD EVM have one end marked DMD End with key pins arranged diagonally that only fit one way onto the DMD board preventing attachment to the wrong side of the board. Place the insulated backer plate on the other side of the DMD board from the flex side with connection pins and carefully tighten the screws. Alternate tightening the screws from side to side until the screws are firm, but not overtightened (SCREW TORQUE REQUIREMENT: 6-8 in-lb [0.7-0.9 N-m]). Figure 2-7 shows the flex cable DMD ends correctly assembled to an example DMD EVM board.
• The other end of the flex cables attach to the dual DLPC900 controller board. The key pins are arranged laterally symmetric and can be inserted from either side of the controller board. To verify the cables are connected to the correct side of the dual DLPC900 controller board, check that the connection flex pins are facing the pads as shown in Figure 2-6. Place the insulated backer plate on the other side of the controller board from the flex with pins and carefully tighten the screws. Alternate tightening the screws from side to side until the screws are firm, but not overtightened (screw torque requirement: 6-8 in-lb [0.7-0.9 N-m]). Figure 2-7 shows the flex cable ends correctly assembled to the dual DLPC900 controller board.
