VME Bus Address
Address Settings for EJI Boards
The VME bus address for a single EJI board is set at the factory and will not need
to be changed. If you have multiple EJI boards, each EJI board must have a unique
VME bus address. The information in Table 10-1 shows how to set the address
when you have multiple boards in an Adept controller.
The address is set at DIP switch U18 on the EJI board. To operate the switch, use a
small insulated instrument, such as the point of a pencil. Each switch position is a
miniature rocker switch. To open a switch, press down on the side of the switch
marked “open”. The switch is located in the upper right-hand corner of the board.
Address Settings for Multiple Servo Boards
If you have MI6/MI3 boards installed along with an EJI, each board must have a
unique VME bus address. Check the address settings on all boards to make sure
they are all different. If you purchased the Adept controller from Adept with all
the motion boards installed, the correct DIP switch settings already will have been
set for you by Adept.

The position notation on DIP switches can vary. If the switch is marked open/closed, then open = off
