Terminating Resistor Specifications
DeviceNet requires a terminating resistor to be installed at each end of the trunk. The resistor requirements are:
• 121 ohm
• 1% Metal Film
• 1/4 Watt
IMPORTANT: Terminating resistors should not be installed at the end of a dropline, only at the two ends of the
trunkline.
DeviceNet Connector
The DeviceNet Option Board uses an open style, pluggable, screw connector that conforms with the DeviceNet
specification. The male connector is resident on the Option Board. One mating female connector is supplied
with each DeviceNet Option Board. Figure 4.3 shows the pinout, orientation, and placement of the male
connector on the DeviceNet Option Board.
