Description

DB-25 Male to DB-9 Female Serial Modem Cable RS-232 AT Modem Null Adapter

This is an unbranded RS-232 serial modem cable with a DB-25 male connector on one end and a DB-9 female connector on the other. Cables of this type were widely used to connect AT-style external modems — which typically featured a DB-25 serial port — to PCs and workstations equipped with a 9-pin DB-9 COM port. Both connectors use standard thumb-screw retention hardware for a secure fit.

  • Connector B: DB-9 Female (9-pin D-sub)
  • Interface: RS-232 serial
  • Cable jacket color: Beige/ivory
  • Both connectors fitted with thumb-screw retention hardware
  • Brand: Unbranded
  • Includes: cable only

Applications

DB-25 to DB-9 RS-232 serial cables are a classic connectivity staple in legacy computing and industrial environments. They are most commonly used to interface external AT-style modems — which shipped with a DB-25 DTE serial port — to computers that provide a 9-pin DB-9 COM port. Beyond modems, this cable type connects a wide range of RS-232 serial devices: label printers, barcode scanners, CNC machine controllers, PLCs, scientific instruments, and terminal equipment that use DB-25 as their serial interface. RS-232 serial connections remain in active use in industrial automation, embedded systems, and legacy equipment maintenance, making these cables a practical item to keep on hand for troubleshooting and integration work.

Condition: Used
This DB-25 Male to DB-9 Female RS-232 Serial Modem Cable has been inspected and is in good condition.
