Configuring the MP Modem to Report GPS and I/O
Data
Digital I/O setup
The Digital Input/Output window (Tools > Options > MP > Input/Output > Digital I/O) is used to configure devices on the two digital I/O and two digital input ports. Each tab corresponds to a pin:
Digital Tab | Connector Pin |
|
|
I/O 1 | Input or output on pin 3 |
|
|
I/O 2 | Input or output on pin 11 |
|
|
Input 3 | Input on pin 4 |
|
|
Input 4 | Input on pin 12 |
|
|
To configure a digital sensor or gauge, select the tab that corre‐ sponds to the pin you are using and complete the fields as follows:
•Label: Provide a description of the sensor or gauge, up to 20 characters in length.
•Type: Select Input, Output, or Not used. (Output is not available on tabs 3 and 4.)
•Logic low name: Describe the state of the device at logic level low, up to 20 characters in length. (For example, if a switch in the off position leads to a logic low, you could choose to label it Switched Off.)
•Logic high name: Describe the state of the device at logic level high, up to 20 characters in length (such as Switched On).
•Alarm logic level: Assign an action associated with the I/O port:
·high: A notification is sent, and the event is logged, if the state changes from a logic low to a logic high.
·low: A notification is sent, and the event is logged, if the state changes from a logic high to a logic low.
·log only: No notification is sent, but any change in logic level is logged.
The name and location of the log file is specified in the Input/Output window (Tools > Options > MP > Input/Output). By default, the log file is located in the program folder or user folder and is called MpIoLog.txt.
•Current value: Shows the current value of the port.
