Connection to Open Collector Output
To connect with open collector output, an external power supply is
necessary. Some motor drivers also provide the power source.
The connection between cPCI-8168, encoder, and the power sup-
ply is shown in the following diagram. Please note that the exter-
nal current limit resistor R is necessary to protect the cPCI-8168
input circuit. The following table lists the suggested resistor value
according to the encoder power supply.
