Direct device link

The Tripp Lite P450-006 is a 6 ft null modem cable with DB9 female connectors on both ends. Foil shielding and gold-plated contacts reduce interference and maintain signal quality. It connects two serial devices that require a cross-wired configuration. Molded construction protects the terminations during repeated use.

Serial equipment installers

Technicians linking legacy DTE hardware such as industrial controllers, point-of-sale terminals or older networking gear will find the pin-out matches the required null modem layout. Installations needing a male interface or a different pin arrangement must source an alternative cable or adapter.

Female-to-female gender

The defining specification is the DB9 female-to-female termination, which only mates with male ports. If the target equipment presents female ports, this cable cannot connect them without a gender changer.

Questions about this item

Will the DB9 female connectors need replacement after repeated plugging cycles?

Gold-plated contacts resist corrosion and maintain conductivity over many mating cycles, reducing the need for connector replacement.

What is the first limit reached when the cable runs at maximum baud rate continuously?

The 6 ft length keeps signal loss low, so the practical limit is the serial port's own buffering rather than the cable itself.

Does the foil shielding add noticeable heat or power draw during all-day operation?

The passive cable draws no power and generates no heat; the foil shield only blocks external EMI/RFI without affecting temperature.
