### Parameters

* **Operation Type** *- **Set GPI State*** - Allow to enable or disable a general purpose input port (GPI).
  * **Port Number** *\<numeric>* - The input port number to set the state.
  * **Enabled** *\<string*> - If the speciifyed input port is to be enabled or disabled.<br>
* **Operation Type** *- **Get GPI State*** - Allow to determine if a general purpose input port (GPI) is enabled or disabled and its current state (low/high).
  * **Port Number** *\<numeric>* - The input port number to set the state.
  * **Target Enabled** *\<numeric>* - Will get 1 if this port is currently enabled and 0 if it is disabled.
  * **Target State***\<numeric>* - Will get 1 if this port is currenytly high (true) and 0 if it is low (false).<br>

* **Operation Type** *- **Set GPO State*** - This allows to change the sate of a general purpose output port (GPO) to high (true) or low (false).
  * **Port Number** *\<numeric>* - The input port number to set the state.
  * **State** *\<numeric>* - The new state for the output port o-Low(false) or 1-High(true).<br>
* **Operation Type** *- **Get GPO State*** - This allows to get the current sate of a general purpose output port (GPO).
  * **Port Number** *\<numeric>* - The output port number to get the state.
  * **State** *\<numeric>* - This will get the current state of the output port to 0 if low(false) or 1 if high(true).
