Non-Isolated Connection

If galvanic isolation is not required, then the GPI port can be used to provide its

own supply for the opto-isolators. In this mode, the common cathodes connected

on pin 11 must be connected to the chassis ground on pin 10. The +5V supply on

pin 9 is then used to trigger memory recalls by switching it to pins 5-8 as

required.

Simple Mode

The diagram above shows four switches connected individually to the four input

lines on the GPI. Simple Mode allows for the recall of four contiguous memories

triggered by pressing one of the four switches. These can be momentary as

shown, or may be latching if some form of feedback is required locally. By

default, the memories recalled will be numbers 01-04, but this can be changed by

adding an offset through GPI > Mem. Offset

Mem. Offset Mem. Offset

Mem. Offset which will move the starting

number, so an offset of 2 will recall locations 03 – 06 and so on.

Non-isloated connection.

Connect pin 10 to pin 11 to

join grounds.
