Connect to the Network with a Tap
Perform the following steps to connect the module to the network using a tap.
1. Remove and save the dust caps from the ControlNet network taps.
2. Connect the tap’s straight or right-angle connector to the module’s
BNC connector.
ATTENTION
Do not allow any metal portions of the tap to contact any conductive
material. If you disconnect the tap from the module, place the dust
cap back on the straight or right-angle connector to prevent the
connector from accidentally contacting a metallic grounded surface.
