LVDS Flat Panel Video Connector (CN19)
Table 13 provides the pinout of the Flat Panel Video connector (CN19). FP_VCC is configured for +3.3V by
default. Contact RTD to have FP_VCC configured for +5 V. FP_VBKLT can be either +5 V or +12 V, and can be
selected with JP9. See Jumper Settings and Locations on page 92 for more details.
