After the terminal block is fully attached to the option unit, tighten the
screws on the left and right sides of the terminal block. (Tightening torque:
0.5 to 0.6 (N
x
m) or 4.4 to 5.3 (inch-lbs))
Note: Be sure to put the option cover back on after all wiring is completed.

Termination Resistor Connection
A network termination resistor (121
Ω, ±1%, 1/4 W) must be connected only to nodes of the
two ends of trunkline. Refer to ODVA specification for more details on DeviceNet
termination.
◆
Communication Cable Specifications
Refer to the ODVA website for more information on network cabling.

Cable Length
■
Trunk Line
The maximum allowed trunk line length depends on the type of cable used and the network
baud rate. The total cable length includes the length of the trunk and the sum of all the drop
lines.
