2.4 Connecting to a Network
This section consists of two parts: connecting to a DeviceNet network, and connecting to a
CAN network.
2.4.1 Connecting to a DeviceNet Network
Connect either a DeviceNet Trunk or Drop cable to the 5-pin connector according to the color
code in Section 1.5.1,
. Make sure that all strands of wire go into the connector,
as bent strands may cause shorts to the adjacent terminal.
Directly connecting DeviceNet Trunk cable is not recommended due to the mechanical stress
placed on the connector by the heavy trunk cable. If you must attach trunk cable, secure it so no
undue stress is placed on the 5-pin screw terminal connector.
2.4.1.1 Termination
The card does not have a built-in termination resistor. Each network must have
two termination resistors—one at each end. Always refer to the DeviceNet Specification
(see Section D.2,
) for proper network termination and wiring directions.
2.4.1.2 Power
for basic network guidelines, and to the DeviceNet Specification
for proper powering directions.
2.4.1.3 Grounding
The network shield should be connected directly to earth ground at a single point in the network.
Refer to
for basic network guidelines, and to the DeviceNet Specification
for proper grounding directions.
