  • Match cable diameter to connector range
  • Avoid extremes of diameter limits
  • Make sure length is sufficient

⚡ EMI Protection

  • Use shielded connectors near VFDs
  • Maintain 6" separation from power cables
  • Ground shields at one end only

🌡️ Environmental

  • Consider temperature cycling effects
  • Account for chemical exposure
  • Plan for vibration and shock loads

🚨 Emergency Troubleshooting Guide

❌ No Connection

Quick Fixes:

  1. Check cable seating in connector
  2. Verify pin-out
  3. Test with known good connector
  4. Inspect for corrosion/contamination

⚠️ Intermittent Connection

Check These:

  1. Loose connector coupling
  2. Vibration-induced movement
  3. Temperature expansion/contraction
  4. Cable strain at connector

📉 Slow Performance

Performance Issues:

  1. Check for EMI interference
  2. Verify cable category (Cat5e minimum)
  3. Test cable length limits
  4. Monitor error rates on switch
