Output from GPI
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 ImagestoreHDTV 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 .
Create a GPI output
To create a GPI output, display the relevant GPI then press the enter key. If
the GPI is unused > None < will be displayed on the front panel. Press the
enter key again then using the arrow keys ⊳ display the command to be
added to the GPI Output and press enter to add it. Only a single function may
be added to a GPI Output.
The options are:
