Purpose:

Model railroads use sensors to inform the computer of the change in conditions. The most common sensor is used to indicate whether a block of track is occupied by a locomotive or other rolling stock. If it is occupied, other action can be taken such a changing a signal or a turnout aspect.

Transponders are sensors that can tell the computer the identify of the locomotive or other rolling stock equipped with a transponding mechanism now in a block.

Another commonly used sensor is used to confirm the status of a turnout. Is it closed, thrown or unknown? This feedback is insurance that the turnout command has been correctly implemented by the railroad equipment.

MRRM will support input messages from each of these sensors in the future. Two sensor feedback bus technologies are being investigated: Loconet feedback and CMRI feedback.

Screen Images:

Digitrax support up to 4095 unique sensors. We provide a mechanism to set your standards for sensor address ranges for each sensor type supported.

Data Description:

Sensor Type - MRRM currently supports the following sensor types: BODs (BDL15x, SE8c, DS54). We anticipate future support for turnout position feedback.

Lower - the first sensor address for this sensor type

Upper - the last sensor address for this sensor type

Function Descriptions:

This information is for configuration management purposes only at this time. No functions are defined.

How to Use:

Document the sensor address range for each type of sensor that you use
