Connect to the Network Using a Tap
Follow these steps to connect the module to the network with a tap.
1 . Remove and save the dust caps from the ControlNet taps.
2. Connect the tap’s straight or right-angle connector to the
module’s BNC connector.
TIP
For network connections we recommend taps with a
straight connector (1786-TPS or 1786-TPYS) because of
the location of the BNC connectors on the bottom of the
module.
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.
