The DLP single DLPC900 EVM requires an
appropriate DMD EVM, such as the DLPLCR65EVM.
- The flex cable provided with
the DMD EVM has 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 4-9 shows the flex cable DMD ends correctly assembled to an
example DMD board.
- The other end of the flex
cable attaches to the single DLPC900 controller board. The key pins are
arranged laterally symmetric and are able to be inserted from either side of
the controller board. To verify the cables are connected to the correct side
of the single DLPC900 controller board, check that the connection flex pins
are facing the pads shown in Figure 4-8. Place the insulated backer plate on the other side of
the controller board from the flex side 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 4-9 shows the flex cable ends correctly assembled to the
single DLPC900 controller board.
