Never connect the shield to ground at both ends. Doing so can produce unwanted oscillations in the
signal wires.
External Resets and Controls (Hardware)
Five inputs to the 15-pin connector help provide extra control without having to go through the
keyboard. To activate the external resets and controls, connect the respective pin to the “Common for 1
– 5” pin. See Figure 4.
Pins 1 - 4 are edge-triggered; use
momentary contact switches to activate
them. Pin 5 (enable programming) is an
on/off function; use a single-pole toggle
switch for it. See Figure 5.
