Digital output channels

Digital outputs are sink channels available on EDIO layer and eXRCPU layer connectors. Configure digital outputs on the Output channels page.

  • Name: The channel name must be unique and contain valid characters (invalid characters are single and double quotes, '\', '@', '#', '&', '<' and '>'). Invalid channel names are 'true' and 'false' (case sensitive).
  • Description: Enter an optional detailed description of the channel.

EDIO layer specific configuration

  • Input channel: Select the desired input channel from the list of available logical channels.
  • Output mode: Select the desired output mode from the following options.
    The terms “Set sink” and “Clear sink” relate to closing and opening the switch that allows current to flow to ground or not. For example, an LED will illuminate when the input channel is logic TRUE (i.e., channel value is 1) when a “Set sink” option is used. Use the “Clear sink” to invert this control logic.
    Select one of the “latched” options to have the output stay in the same state after the input channel first transitions to logic TRUE. Select one of the “unlatched” options to have the output state change as the input channel changes from one logical value to the other logical value.
    • Set sink unlatched
    • Clear sink unlatched
    • Set sink latched
    • Clear sink latched

NOTE
For the following 2 parameters, the term “Low” is equivalent to “Set sink” and the term “High” is equivalent to “Clear sink”.

  • Initial state: Select the desired output state to be set when the test is started (Low or High).
  • Final state: Select the desired output state to be set after the test is stopped (Low, High, or No action which means the output will remain in the state it was in when the test run was stopped).
  • Transducer power: This is applicable to the EDIO output channels only; the eXRCPU outputs do not provide power. Select the desired power setting (Nominal 5 V or 12 V). If the transducer power is changed, all digital input and output channels and all pulse counter channels on the same EDIO layer and same Bank are changed to the same power setting automatically.
