5.
Select the proper type of 9-pin D-sub CN5 connector and network cable.
for details on cable selections and cable lengths.
Refer to the PROFIBUS-DP website at www.profibus.com for more information on cables and connectors.
6.
Connect the option to the network using a 9 pin D-sub connector as shown in
.

PROFIBUS-DP Termination
The option does not have a termination resistor. The termination resistance must be set on the final drive in the
network using a switch on the 9-pin D-sub connector. Make sure that only the connector for the final drive in the
network has a termination resistor; communication problems may arise if any other network drive has a
termination resistor.
Use only the input side cable entry as shown in
when connecting both ends of the network. Most 9-pin
D-sub connectors have a function for disconnecting the output side of the cable. Communication will not be
possible between devices if the connector is reversed. Most connectors have arrows indicating the input and
output sides.
