- Page 2 IMPORTANT NOTES: If your module generates a negative voltage for contrast control, you MUST ensure that J1 is removed from the EDP-I! It has been our experience that most modern modules do not require a negative voltage for contrast until the temperature reaches -30 C.
- Page 3 A and K terminals to the Header labeled “A” and “K” using external wires. Also, note that this pinout uses an additional Enable line, E1. The EDP-I software will automatically enable this when the 40x4 module is selected. If your 40x4 module doesn't match this pinout, you'll have wire an adapter cable.

Additionally, pins 15 and 16 may be reversed! NOTE: Some modules with a bottom connector will need to use the T1 pinout! Check your module.
- Page 5 We have tried to address the majority of the pinouts that we’ve seen. However, there are far to many variations for one board to cover them all. The EDP-I should be able to handle any module that supports the pseudo-standard 7 bit interface if you can solder up the correct wires.
- Page 6 EDP-I General Operation The EDP-I interfaces to the industry standard “AT” style keyboard using a PS/2 sized connector and provides a ‘line’ based editor. This allows users to enter/edit one line without disturbing other lines on the display. The exceptions to this are: The cursor will wrap-around to the next line when typing text;...
