• Notes

• The NSM 3101 is a two piece 100 disc CD changer system.
  This CD management system is used in commercial jukeboxes worldwide.
  It is a sleek metal and smoked glass unit.

  CD3101AC  is the CD changer, which accepts two 50 disc  magazines.
  CD3101 is the controller. It is a stand-alone single disc player, a Philips CD634 unit modified by NSM.
  They are connected with a COM1 cable.
  
  Data is transfered in ASCII-code between the CD changer controller and the host computer (PC) via a 9-pronged RS232 interface.

  NSM-CD3101AC has each tray position individually numbered. There are two banks of 50 trays, each bank swings out for easy disc loading. A smoked glass door swings down in front, latches at the top.

  The pickup serves to transport the CDs between the magazines and the player.
  The lift is moved by a step motor controlled by the micro processor of the pickup controller. The distance between 2 CD slots is 8 motor steps (1 opto step).
