CIM Jumper Settings
The CIM has jumpers that determine the board's attributes. Ensure the necessary jumpers are set depending
on the position and function the board is serving. Jumper settings are reviewed in the following tables. Please
note the jumper locations in the diagram below.
Figure 47 – CIM Jumper Locations
CIM Global Master Jumper – J3 (Master/Slave ACUs)
Jumper J3 sets the CIM as global master. Only one (1) CIM can be designated as a global master. All other
CIMs are designated as slaves.

On a communication bus with elevator control units only, a global master CIM is not applicable. Do not
place a jumper on J3.

Jumper J4 must be set on the module that is designated as CIM 0. This is the module with either the direct
serial connection to a PC or a network connection via a NETCOMP to the system communication software.
