A.4 Model CM-C VSM Oven Module: Rear Panel
The rear panel of the Model CM-C VSM Oven module contains an address selector, two guide
holes, and the CAN connector through which the module sends and receives network data and
receives power.
A.4.1.1 ADDRESS SELECTOR
Each module on the CAN bus must have a unique 5-bit binary address. The selector on the back
panel is used to set the four least significant bits, while an internal jumper sets the most
significant bit. If the selector is set to “0,” the module uses its default address. For a Model CM-C
VSM Oven module, the default address is 12.
A.4.1.2 GUIDE HOLES
The two guide holes are used to align the connector with a low-power receptacle on the Model
1000 Modular Control System.

A.4.1.3 QD CAN CONNECTOR AND PINOUT TABLE
The QD CAN connector is the main communication connection for controlling the Model CM-C
VSM Oven module. The CAN network signals (CAN High, CAN Low) are connected to all other
CAN modules on the bus and to the PC. Power (±24 volts), reset, and sync signals also are sent to
the module though this connector.
