Black Box RS232 serial cable DB9 to DB25 male female 50ft beige

Black Box Corporation

Black Box EVMTBMC-0050 RS232 AT Modem DB9/DB25-9-CDTR F/M 50FT serial cable

SKU CH-2T1D-1660P

A 50-foot serial cable with 9-conductor 24 AWG wiring, foil shielding and DB9/DB25 connectors for RS-232 modem or printer links

  • Connect AT PCs to any-speed async modems via RS-232
  • Nine-conductor 24 AWG wiring handles full modem handshake signals
  • Foil shield plus drain wire rejects noise in harsh areas
  • Low capacitance design preserves signal quality over the 50 FT run
  • Non-moulded removable hoods allow quick field repinning when needed

RS-232 AT modem cable

This 50 FT RS-232 cable connects an AT or compatible PC to asynchronous modems at any speed. The DB9 female to DB25 male ends suit serial printers, modems and other legacy peripherals. Nine conductors at 24 AWG carry the full handshake set. Foil shield with a drain wire protects data in noisy environments.

Sustained signal integrity

Low capacitance keeps attenuation minimal across the full 50 FT run during continuous sessions. Foil shielding and the drain wire reject EMI that would otherwise corrupt long transfers. Removable hoods allow field repinning so a damaged pin never ends the link. The assembly is guaranteed for life.

9-conductor handshake support

The nine-wire layout carries every RS-232 control line including CD, TR and RI for complete modem control. Cables with fewer conductors drop secondary signals and break hardware flow control. Verify the peripheral expects a full 9-wire DB25 interface before ordering.

Questions about this item

Does the foil shield and drain wire keep interference low when this 50 ft cable runs all day?

Yes, the foil shield and drain wire are designed for noisy environments and maintain low capacitance over the full 50 ft length.

Which ports must my equipment already have to use the DB9/DB25-9-CDTR F/M connectors?

One device needs a DB9 port and the other a DB25 port; the cable provides the female/male gender change and the 9-conductor pinout including CD and TR.

Will the 24 AWG conductors and 9-conductor layout work with an older RS-232 modem that expects a 25-pin interface?

The cable is built to the RS-232 standard with 24 AWG wires and all nine conductors, so it connects a DB9 AT/PC port to a DB25 modem without signal loss.
