Important! In order to avoid EMC problems, all external cables must be shielded. The D-sub hood must be of metal
or metalized with the shield connected. External boxes of metal (metalized) with the shield connected.
Connect GND to metal hood of D-sub.
Standard internal signals.
Max recommended distance to display 1m, keyboard 10m.
Pin 14 and 15 are backlight excitation of the display.
Max 10mA.
Use large cable area. Max 5mV voltage drop in cable.
