Direct PC-to-PC serial link

This six-foot null-modem cable connects two DB9 female ports so that two DTE or DCE devices can exchange data without a modem. The transmit and receive lines are crossed internally to prevent signal conflict. Foil shielding blocks EMI and RFI from nearby office equipment and fluorescent lights. Thumbscrew connectors give a quick, tool-free connection every time.

Passive cable — no thermal or power concerns

The assembly draws no power and generates no heat, so it adds nothing to system thermals or acoustic load. Shielding simply preserves signal integrity across the 1.82 metre run. No active components mean there is no fan noise, no coil whine and no power draw to budget for.

Rugged overmoulded build for daily use

Overmoulded strain relief protects the solder joints when the cable is routed behind desks or through trunking. Beige PVC jacket matches legacy office equipment aesthetics. Thumbscrews lock securely without tools, making swaps fast during maintenance. Female-to-female pinout suits direct PC serial-port linking; it will not connect a PC to a modem or printer without a gender changer.

Questions about this item

How do I connect this DB9 female-to-female null modem cable between two PCs?

Plug each DB9 female connector into a PC serial port and tighten the thumbscrews for a secure fit; the crossed transmit and receive lines handle the null modem function automatically.

What upkeep will the foil-shielded, overmolded cable need over time?

No scheduled maintenance is required; inspect the thumbscrews and strain relief occasionally and replace the cable if the shielding or moulding shows damage.

At what length does RS-232 signalling typically degrade on this cable type?

Reliable operation is specified for runs under 100 feet, so the 6 ft length stays well within the safe range.
