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:
