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 78 – CIM Jumper Locations
CIM Global Master Jumper – J3 (Master/Slave ACUs)
Jumper J3 sets the CIM as global master. Designate only one (1) CIM as a global master. Designate all other
CIMs as slaves.
Table 17 – CIM Global Master Jumper J3
Set global master CIM at least busiest ACU. Set global
master CIM connected to door control unit only when using
ACU to ACU communication on CAN Bus 2.
Do not set a CIM as global master that is connected to an
elevator control unit. See note below.
Note
On a communication bus with elevator control units only, a global master CIM is not applicable. Do not
place a jumper on J3.
