CM10050
: “T” Connector
CM10051
: male terminator /
CM10052
: female term.
Note regarding connectivity of “T” Connectors:
When connecting a “T” connector to a component (for example, i8320 i2 module)
always install via the middle connection (“NODE”).
When connecting a “T” connector to a CANBus cable (for example, CM100xx)
to connect components that are far from each other, always install via the male/female end of the
connector (whichever applies).
Hand-tighten after the connection is made.
Do not tightly tie down the “T” connectors, as this will create stress.
The Network must consists of a single cable run to which devices are connected to it by means of a “T”
Connector. All products must connect onto the node part of the “T” connector. Each end of the cable
must have a terminator. It is essential there be a total of two and only two terminators.
The cable consists of two twisted pairs and a shield connection, which shields each twisted pair and
provides an overall shield. One pair is the CANbus signals referred to as CAN Hi (white) and CAN Lo
(blue). The other pair is the power V+ (red) common (black). The total number of connections made
through the connectors is
fi ve. The pinout and wire colors conform to the DeviceNet Standards and are
