The EMTRAC Interrogator System enables transit agencies to automatically download activity logs from—and upload firmware and database updates to—Personal Navigation Units (PNUs).
EMTRAC Interrogator at a Rail Operations Center
The EMTRAC Interrogator System can be used at rail operations centers and maintenance facilities, as well as other locations.
As equipped personnel return to the operations center after shift, their PNUs are placed at charging stations, which is within radio range of the EMTRAC Interrogator.
The Interrogator utilizes secure frequency-hopping spread spectrum radio to download activity logs from the EMTRAC units, and this data is forwarded to a server running the EMTRAC Central Monitor software, where it may be viewed by authorized personnel.
