    6ft AT Modem DB9F/DB25M Molded Cable

    While legacy PCs (post IBM PC/AT) typically use 9-pin RS-232 plugs, external modems are usually equipped with 25-pin RS-232 sockets. You can depend on Monoprice to have the cables you will need for this type of connection!

    This cable features a female DE-9 (DB-9) socket on one end and a male DB-25 plug on the other. The 9 pins of the DE-9 connector are wired to 9 of the pins on the DB-25 connector as shown in the following table:

    DE-9 (DB-9) DB-25 Function
    1 8 Data Carrier Detect (DCD)
    2 3 Receive Data (RD or Rx)
    3 2 Transmit Data (TD or Tx)
    4 20 Data Terminal Ready (DTR)
    5 7 Signal Ground (SGND or Gnd)
    6 6 Data Set Read (DSR)
    7 4 Request To Send (RTS)
    8 5 Clear To Send (CTS)
    9 22 Ring Indicator (RI)

    The connector heads are molded onto the cable and each includes a pair of thumbscrews to secure the connector to the PC or modem.

    Pin-out is Dead On
    Another wonder product from Monoprice. The pin-out table above is accurate, the build quality is good, and it's cheap! In addition to use as an AT-modem cable, you can also modify this cable to work as a DB9-DB25 null modem (w/ handshaking) cable.

    PROS: It's cheap, the build quality is good, and the pin-out is dead on.

    CONS: None.
