Connector
The EL552.256-Q2 display package includes a DC/DC converter and a cable for
connecting it to the display. As shown in Figure 2, the display is connected to the
converter (Connector J1 to J3) with the supplied cable, then the converter has a
connector (Connector J0) for interfacing with the customer design.

Both the J0 and the J3 are low-profile male PCB header connectors with dual-row
contacts on 0.00" centers. Video signals and +12 V DC power are connected to
Connector J0 on the DC/DC through a 16-pin T & B Ansley connector, part
number 609-1630 or equivalent with the pin assignment shown in Table 2.
