Parallel Automation Interface
Pins 1 through 7 of the DB25F automation connector are “control” pins that accept contact
closure or open collector pulses to ground to select formats. Pulsing pin 8 low toggles the mute
state. Pins 9 and 10 are used for remote fader operation. Each input sources a 400uA when
grounded. A pin needs to be pulled below 2.6V for 50ms or more for the JSD-‐60 to recognize it
as low. On pin 13, a +5V, 100mA supply is available to power the JSDV-‐80 Remote Fader. An
automation return is on Pin 12.
