GPIO
GPIO settings page provides the status for GPI pins and also helps the user to set the status of GPO pins. To set a GPO pin HIGH/LOW click on the image of the required pin number.
 Indicates GPIO HIGH
 Indicates GPIO LOW
 Indicates GPIO Unknown state
GPI debounce time - Many of the devices connecting to GPIO port of the FX reader would create spikes during the connection. GPIO Debounce would help to handle the situation. GPIO debounce does not have impact on GPO operations and input operation when the debounce time is set to 0. Also, debounce time is applied in all input pins and pins must work independently of each other. The user can enter the debounce time in milliseconds. The upper limit of GPI debounce value is 1000 and default value 50 is set if it is not in the range. Once the time is set the events are delivered as wells as callback functions are called only after the debounce time expires provided the pin state stays in the same level for the debounce time duration.
GPIO Settings - GPIO Settings selection shall help to map the FX reader GPI and/or GPO with Radio GPIO. User allowed to select 'Radio GPIO(X)' for either 'Host GPI(X)' or 'Host GPO(X)'. Where X = 0 (or) 1. If user try to violate this condition, then previous selection will be changed to either 'Host GPI(X)' or 'Host GPI(X)' automatically. GPIO setting is valid for FX7500 Four port reader. GPIO settings options will be disabled, if not supported.
