ControlNet Network Terminator

 

A 75 Ω terminating resistor must be installed on the tap at each end of a trunk-cable section. Terminating resistors absorb the electrical energy of the signal at the ends of the cable to prevent reflections, which interfere with signals that are being sent. Two types of terminating resistors are available depending on the connectors and taps that are being used on a trunk line. There is a BNC terminating resistor (catalog number 1786-XT) and a TNC terminating resistor (catalog number 1786-TNCLXT4).

 

A disconnected drop cable can cause noise on the network. Because of this, a 1786-TCAP is recommended at all unconnected drop cables. The tap dummy load matches the impedance of an operating device to limit noise entering the system through an unconnected tap. This component is different from a trunk cable terminating resistor. In addition, a disconnected trunk terminating resistor can have unpredictable effects to the network, including the inability to communicate due to reflections. Each segment must be terminated with a 1786-XT u
