All Graphi-Qs
include a back panel mounted contact closure connector which can be used for
remotely changing the stored presets. This male 8-pin Phoenix connector is
labeled 1-7 with the last pin marked as C for common. The female connector
comes as an accessory in every Graphi-Q.
Accessing the first seven presets is simply a
matter of connecting the common with one of the 7 pins. Accessing the rest of
the presets involves using set combinations of the pins to achieve a total of
68 possible presets. |
