Ampro Corporation 486E manual Connecting a Flat Panel J3, W10 +5V

Product Reference

Connecting a Flat Panel (J3)

Signals for a wide range of flat panel displays, both color and gray scale, appear on connector J3. Although flat panels of a similar type use similar sets of signals from the video controller, they do not share a standardized interface connector pin configuration. The names of panel control signals vary from manufacturer to manufacturer. Read the description of each signal carefully to determine how each signal is used for the display you choose. Refer to the panel manufacturer’s technical literature to determine how to wire a cable for the panel you choose for your application.

Cable diagrams for Ampro-supported panels can be found on the Utilities diskette.

Jumper W10 is a 6-pin header that allows for selecting the proper voltage required by a particular panel, see Figure 2–8. Two jumper shunts are used to provide adequate current capacity. When jumpered 1/3 and 2/4, +5V is selected to power the panel. When jumpered 3/5 and 4/6, +3.3V is selected.

Caution

Make sure that both jumper shunts are connected as illustrated in

Table 2–30 lists the signals available on connector J3. Table 2–31 shows manufacturer’s part numbers for mating connectors to J3.
