Control Interface Module (CIM)
The Control Interface Module (CIM) is a multipurpose assembly capable
of functioning as the control processor, motherboard, peripheral
interface, and user interface for the Maxum II analyzer. It may be used in
both the Modular Oven and Airbath/Airless Oven configurations of the
Maxum analyzer. This section is related to the use of the CIM in the
Maxum II Modular Oven configuration.
Description
In the Maxum II Modular Oven, the CIM functions as the primary
processor, receiving data and performing analytical calculations, storing
the analyzer application database, communicating and controlling other
installed electronic hardware, as well as controlling external
communications (including network, serial, and I
2
C communications to
external devices). The CIM also includes a user interface for onsite
access to the analyzer.

The CIM assembly consists of a base hardware module (CIMBase), a
processor module (CAC3) mounted on the CIM-Base, a color display
panel, and a touch screen interface mounted over the color display
panel. The combination of CIMBase with CAC3 installed is called the
CIMBoard. The entire assembly of CIMBoard, display, and touch screen
are called the CIM assembly, or simply CIM. The functions performed by
the CIM depend on the analyzer configuration. In the Maxum II Modular
Oven configuration, the CIM functions as primary processor for the
analyzer and also provides interface, software, and control for the
enhanced color touch screen display unit mounted on the analyzer
Mechanical
The CIM may also be installed in a Maxum Airbath/Airless oven
configuration. This function is described in the Maintenance Manual for
the Airbath Airless Configuration Maxum II (part number 2000596-001).
The functional versatility of the CIM allows one set of hardware for
multiple functions, allowing for simplified maintenance and reduced
spare parts requirements.
The CIM is housed on the door of the Maxum or Maxum II. The circuit
boards are mounted on the inside of the door while the display is
mounted in the door, facing out for exterior user access. External
connections are via connectors on the CIM-Board.
