MSS-DEBUG

As a debugger for the Modular Signal System, the MSS-DEBUG monitors signals on the occupancy bus as well as sends occupancy signals to test installations.  It's useful for bench testing signal installations on a module when no larger MSS network is available, or for figuring out why an MSS installation isn't working correctly.  The MSS-DEBUG requires 3x AAA batteries to provide operating power and includes a 1' straight-through ethernet cable for attaching it to an adjacent MSS node.

Features

  • Diagnostic LEDs indicate status of MSS signal lines:
    • Local Block Occupancy
    • Approach Occupancy In (to node)
    • Advance Approach Occupancy In (to node)
    • Advance Occupancy Out (from node)
    • Advance Approach Occupancy Out (from node)
    • Diverging Approach In/Out (to/from node)
  • Switches for toggling each signal line to test module response
  • 12V bus pull-up voltage for testing bus segments without pull-ups (e.g. MSS-CROSSOVER module)
  • Compliant with the Modular Signal System 2.0.1 standard
  • Powered from 3x AAA batteries
