Example:
Assigning a value of 15 to ‘VO IP Shuf Chan 1’ will copy the mono audio
feed coming into channel 1 of the voice over input to all 4 output channels.
GPI Outputs Assign
A GPI port may used as an output to trigger external devices and its active
status, (on), is defined by the output being internally pulled to ground by a
"Darlington" configured transistor such that an active low will be represented
by +0.7V. Lamps or relays attached to an output GPI may use the GPI +12V
supply (pin 8) but the maximum current drawn from this supply should not
exceed 500mA.Where a GPI output is used to drive a relay coil, reverse
voltage protection diodes should be incorporated into the circuitry to protect
the Easysound Standalone from voltage transients.
Only GPI 1 to GPI 7 may be assigned as a GPI Output but each GPI may
have a condition assigned whether it is set on or off, i.e. GPI Out x On or GPI
Out x Off .
