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.
