Here is a brief outline of the procedures you will follow as you construct your
network using 1770-SC station connectors and droplines.
attach an electrical connector to the dropline
test the connector for electrical continuity
test the connector for electrical shorts

Attach an Electrical Connector to the Dropline
The first step in constructing a DH or DH+ cable system is to attach an
electrical connector to the dropline. Each dropline in your network must have an
electrical connector to plug the dropline into the node interface module.
The type of electrical connector you attach to the dropline depends upon the
device you are connecting to the network. Refer to Table 3.A for the most
common types of electrical connectors used with the different devices.
