9.3 CAN
CONNECTIONS
9.3.1 General
Information
The installation requires a CAN cable between every two “CAN devices” and CAN terminators on each
end of the CAN link. The M7200 mobile radio is considered a CAN device, and each CH-721 control
head in the installation is also considered a CAN device. Figure 9-6 illustrates CAN cable and CAN
terminator connections for a single control head installation. Figure 9-7 illustrates this for a multi-head
control head installation where, for example, one control head is located at the main operator location and
another is located near the rear of the vehicle. Because CAN devices do not have internal terminators, the
CAN link must be terminated at both ends via a CAN terminator.
