Tips

Before purchasing, verify that both devices have male DB9 ports or that you need a female-to-female extension. For longer runs, consider using a null modem cable if you need crossover wiring, but this straight-through cable is perfect for most direct connections. Always tighten the thumbscrews to prevent accidental disconnection in industrial environments.
