    1ft 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.

    I have a projector that was having color issues seemingly from a bad pin or connector. I ordered this cable to replace the damaged cable. It came in a few short days and worked beautifully upon testing. I am VERY happy.!

    Great Replacement Cable

    Pros: Works like a charm and reasonably priced.

    Purchased a used InFocus LP120 projector that was missing its accessories, specifically the DVI to VGA interface cable. Searched online and Monoprice comes through in the clutch.

    Pin-out is Dead On

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

    Cons: None.

    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.

    Replacement Cable for Projector

    Pros: It worked and it was cheap

    Cons: None

    Bought this to replace a cable on a little Dell projector. Apparently, the education department let someone borrow their projector and whomever used it brought back the projector but kept the cable (Why, I do not know). I looked at CDW (one of few vendors we're allowed to purchase from) and they wanted $30. for the same cable. At $5.65, I went ahead and paid for it out of pocket.

    Replacement Cable for Projector

    Pros: Exactly what was needed

    Cons: shipping cost twice as much as the part.

    As most people know, the price for cables at most places are expensive. MonoPrice had this cable that is exactly what we needed for a very low price. Even though the price is cheap, the part is not cheaply made. The reason for an 8 is because of the high cost to ship. But overall, it was still about 1/3 the cost of others.
