• up to 126 Grapevine Nodes (plus weighscale at #127)
• each Grapevine Node can control
  • 96 signals or 32 switchmotors
  • up to three ASD (24 detected blocks in total)
  • up to 8 "parallel/analog inputs" (on/off switches)
  • has a parallel output for
    • a printer, or
    • a digital fastclock, or
    • hotbox display, or
    • 8 additional "parallel/analog inputs"
  • analog fastclock
  • highway crossing flasher
• Grapevine Node address can be changed in software
• control selections are made in signal software
  • selections can be changed at any time
  • change selections as your Grapevine network grows
• Grapevine nodes can hitched together in any order
• fastclock code built-in to each node, you can put clocks anywhere
• weighscale, node 127, has its own node
• 5-volt regulator built-in, requires only 1 power supply +9 to +18 volt somewhat filtered DC
• all connections are by plugs and sockets - no soldering
