Digital Out

Digital Output Count :

The count of Digital Inputs is obtained by using:

myIOServiceClient.RequestDigitalOutputs().DigitalOutputs.Count

Example output for this call is:

2

Digital Output Switching:

The Digital Out 1 and 2 wires allow a voltage supplied load to sink to ground when the respective pin state is assigned to High (1) and then set.

Changing the state is a two part process -

The Digital Out 0 index pin is ASSIGNED High by using:

myIOServiceClient.RequestDigitalOutputs().DigitalOutputs[0].State = Services.IO.PinState.High

After the pin state is assigned to the Digital Output, the digital output must be SET using:

myIOServiceClient.SetDigitalOut(myIOServiceClient.RequestDigitalOutputs().DigitalOutputs[0])

The current assignment of the Digital Out index 0 can be determined using:

myIOServiceClient.RequestDigitalOutputs().DigitalOutputs[0].State

Verification of Digital Output Set Success:

Reading the DigitalOutputs[x].State only gives the assigned value, if the SetDigitalOut method failed, the assigned value and actual circuit state could be different. To help avoid issues, SetDigitalOut returns a SetOutputResponse object with an ErrorDescription field that can be used to verify no errors occurred. An example of how this might be executed is:

SetOutputResponse digitalResponse1 = myIOServiceClient.SetDigitalOut(myIOServiceClient.RequestDigitalOutputs().DigitalOutputs[0]);
if (String.IsNullOrEmpty(digitalResponse1.ErrorDescription))
     { Console.WriteLine($"Setting Digital Out 1 Success"); }
else
     { Console.WriteLine($"Setting Digital Out 1 Failed. Error: {digitalResponse1.ErrorDescription}"); }

Additional Digital Output Information:

Open Drain FET output pulled high to Vbatt through a 10K pullup resistor.

Designed to switch the negative side of a signal
