Video Connector (J3)
Video signals and LCD display power (V
L
) are applied via a polarized 34-pin dual-row 2
mm pitch header with gold plated (30
µ
") contact surfaces and ejector/latching ears. The
connector is equivalent to a Samtec EHT-117-01-S-D-RA and the recommended mating
cable is a Samtec TCSD-117. Consult your Samtec representative (1-800-SAMTEC9) for
cable and connector options. Note that J3 is electrically and mechanically independent of
the backlight assembly.
