Industrial Network and Deterministic Backplane Characteristics
The 1786-BNCP provides physical layer integrity required for ControlNet deterministic networks operating at 5 Mbps. It features backplane bus communication velocity compatibility with 1786-TPS taps and ControlLogix / PLC-5 network interfaces. Precision 75 Ohm impedance matching minimizes signal reflection, maintaining high signal-to-noise ratios across multi-drop trunk lines and preventing packet corruption during high I/O density scaling routines.
Frequently Asked Questions
Q: What cable specification is required for proper crimp termination with the 1786-BNCP?
A: The 1786-BNCP requires RG-6 quad-shield coaxial cable to maintain precise 75 Ohm characteristic impedance across the 5 MHz ControlNet physical layer band.
Q: How does Series B differ from Series A regarding mechanical installation resilience?
A: Series B units incorporate enhanced nickel plating on the brass housing and tighter physical tolerances on the bayonet latching ring to prevent loosening under industrial vibration environments.
Field Installation Guidelines
- Strip the RG-6 quad-shield cable using a standard 3-stage coaxial stripping tool to expose the center conductor, inner foil/braid, and outer jacket to exact manufacturer length specifications.
- Ensure the gold-plated center pin is fully seated and crimped onto the inner copper conductor before inserting the cable assembly into the nickel-plated body.
- Torque the outer ferrule using the designated hex crimp tool die to lock the quad-shield braid to the connector chassis, ensuring a low-resistance 360-degree shield earth path.
- Align the bayonet slot with the male pins on the ControlNet tap (e.g., 1786-TPS), push firmly, and twist clockwise until the locking pins seat into the retention detent.
- Verify that minimum cable bend radius limits (typically 75 mm) are respected immediately behind the BNC plug boot to avoid impedance discontinuities.
