# LocoNet Statistics

Advanced LocoNet interfaces like the LocoBuffer series from RR-CirKits or the PRn series from DIgitrax collect statistics on the operation of the attached LocoNet. This window displays those.

The "Update" button requests information from the interface for display.

## LocoBuffer Values

Version
  The version number of the unit.
Breaks
  The number of LocoNet breaks seen since the last time the interface was powered on. This is the number of times that the locobuffer sees a problem with its output message to the loconet and issues a break, that tells the devices that are receiving the data to throw that packet away and the locobuffer then resends the packet.
Errors
  The number of LocoNet errors seen since the last time the interface was powered on. This happens when the Locobuffer detects a problem on a packet it is receiving off the loconet. This should be a result of the sending device seeing a problem with the packet it is sending and issuing a break. The data is not lost when this happens, the sending device then sends the packet again. The worst case is if the Locobuffer seeing a problem with a packet it is receving and the transfitting device does not. The packet is then lost.

## Digitrax PRn

Serial Number
  The serial number of the unit.
PR2 Status
  The status bits from an interface in PR2 (programmer) mode.
Current
  The current being drawn by the track, in some arbitrary units.
Hardware Version
  The version number of the interface's hardware.
Software Version
  The version number of the interface's software.
Good Message Count
  The number of good LocoNet messages seen since the last time the interface was powered on.
Bad Message Count
  The number of bad LocoNet messages seen since the last time the interface was powered on.
MS100 Status
  The status bits from an interface in MS100 (LocoNet adapter) mode.

Some of these are displayed when the interface is acting as a programmer (PR2 mode), and others when it's acting as an interface (MS100 mode).
