    Beware if you are going to use this on a DirecTv HR-24 or H024. I bought this to control my DirecTv with serial commands. It worked flawlessly on my older HR-20 receiver. I got the new model HR-24 and the adapter no longer worked. It would work intermittently, and required a red button reset every couple hours. Same thing on my H-24 (non-dvr) Might be a DTV firmware issue. I tried monoprice item 2276 and had the same problem. I then tried the IOgear model the DTV recommends, and have had no issues, but it's 4 times the price.

    The cable worked just as I needed it to. The shipping was quick and the price was good. I always get my cables from this site. I have actually all ready recommended this site to my whole class as to where to buy there cable that they need for class from.

    Serial to USB Adapter
    Just got a new Dell laptop at work, and lo and behold it didn't have a serial port which I needed for a computer program i use. I needed to adapt to a usb port, so I ordered this adapter. I had a difficult time making the connection initially, but eventually I was able to get it connected. The screw lugs had to be removed because they didn't line up, but the connection seems very secure anyway. Well worth the money.

    PROS: Easy to install software, long cord, works great, great cost.

    CONS: screw lugs didn't match up to male serial connector I needed to convert to
