The NVT Model NV-BNCA is an adaptor used by NVT's IP transceivers to convert from BNC to 2-wire. It ships standard with the NV-EC1701U transceivers, but can be used with TBus products as well. The NV-BNCA may be used mid-span along a wire run whenever conversion between coax and 2-wire cable is required. Eight screw-terminal connections each support wire diameters as large as 16 AWG .051" (1.3mm) and can be used in applications such as: 4:1 fanout, Daisy-chaining, or 4-pair wire connectivity. Screws should be torqued to 2 in-lbs (0.2 Nm). The NV-BNCA is not intended for use with analog video transmision. Product weight: 0.054 lbs (.024 Kg)
