Product Information

Full details

The kenable 000825 Null Modem cable is designed for IT professionals and hobbyists who need to establish reliable serial communication between legacy devices, such as connecting a D9 serial port to a D25 port. This 2-metre cable offers high signal integrity through its foil shielding and gold-flashed contacts, making it a robust solution for data transfer; however, users should ensure their specific hardware requires a 'null modem' configuration, as it is not a standard straight-through extension cable.

Extended Product Information

FAQs

Is this a straight-through cable?

No, this is a null modem cable. It is internally cross-wired to allow DTE-to-DTE communication.

Can I use this for my modern printer?

Most modern printers use USB. This cable is specifically for legacy serial-based hardware.

What is the AWG of the internal wires?

The cable uses 28 AWG wire.

Are the connectors gold-plated?

The cable features gold-flashed contacts to improve signal conductivity.

Does this cable support hardware flow control?

The null modem configuration handles standard serial handshaking, but check your specific device pinout to ensure it matches the wiring of this cable.

Troubleshooting

No data transfer between devices

Verify that your devices strictly require a null modem cable. Some devices require straight-through cables or specific pinout adapters.

Intermittent data errors or signal drops

Ensure both connectors are firmly seated in their respective ports and that no heavy EMI sources are placed directly against the cable.

Pros and Cons

Pros

  • High-quality shielding reduces data errors
  • Gold-flashed contacts ensure reliable long-term performance
  • Moulded connectors offer superior physical durability
  • Optimal 2-metre length for most workstation setups

Cons

  • Not suitable for devices requiring straight-through cabling
  • Serial interfaces are increasingly rare on modern computers
  • Limited to 2-metre reach for fixed installations

Setup, Compatibility & Care

To ensure proper functionality, verify that both your source and destination devices support the RS-232 serial standard and that a 'null modem' crossover configuration is required by your equipment manual.

Compatibility

  • Connector 1: D9 Female
  • Connector 2: D25 Female
  • Interface Type: Null Modem / Serial

Care Instructions

  • Avoid sharp bends or kinks in the cable to protect the internal foil shielding.
  • When disconnecting, pull by the connector housing rather than tugging on the wire itself.
  • Store in a cool, dry place to prevent the grey outer jacket from degrading over long periods of inactivity.
