Installation Instructions

 

  1. Mount the Grapevine™ node, the LCD display and the pushbuttons in the desired locations.
  2. Do not mount the weighscale in its final position just yet.
  3. Review the accompanying diagram for cable connections.
  4. Connect the cable for the Y pushbutton (black) that is marked “0” to the 3-pin header marked  “0” on the top side of the Grapevine™ node printed circuit board.
  5. Attach the cable for the Y pushbutton (black) that is marked “1” to the 3-pin header marked “1” on the top side of the Grapevine™ node printed circuit board.
  6. Connect the 14-pin ribbon cable leading from the LCD display to the 14-pin socket on Grapevine™ node closest to the power connections. 
  7. Connect the 3-pin cables that are marked “3”, “4” and “5” to any of the remaining 3-pin headers on the Grapevine™ node.
  8. Connect the free end of the cable marked “3” to the 4-pin header on the circuit board mounted underneath the weighscale.
  9. Connect one end of the 14-conductor ribbon cable to the 14-pin header on the weighscale, and then connect the other end to the remaining 14-pin header on the Grapevine™ node.
  10. Mount the weighscale in its final position.
  11. Plug a 6 conductor Grapevine™ cable leading from another Grapevine™ node “OUT”  RJ-12 phone socket (or from the RJ-12 socket on the RS-232 to RS-422 adapter) to the “IN” RJ-12 phone socket on the Grapevine™ node for the weighscale.
  12. Plug the Grapevine™ termination cable in the “OUT” RJ-12 phone socket or use a 6-conductor Grapevine™ cable to connect to the next Grapevine™ node.
  13. Crimp the 0.187” female terminal on to a wire from the positive supply voltage.
  14. Crimp the 0.110” female terminal on to a wire for the ground supply voltage.
  15. Press the power terminals you have just crimped, onto the male terminals on the Grapevine™ node.
  16. Turn on the power.  The green LED on the Grapevine™ node circuit board should light.  The LCD display should read “Scale ready…  Press Y to start” and the backlight on the display should light.  If this does not occur, disconnect the power and check your installation.
  17.  If all is well you are ready to start using your weighscale with ProTrakä.
