    How about getting a panel mount female to go with this?

    I purchased one of the very first IBM AT computers with an EGA screen and a 40 meg hard drive. Cost a fortune even with the 50% employee discount. I spend many evenings exploring how this beast worked. One thing that drove me crazy was a graphics library I had gotten (EGAD). Every time I disassembled a section of the code, it would be different. The code for drawing a line would change from invocation to invocation. It was only much later when I had to write my own graphics library that I realized what was going on. The library had used self modifying code to optimize the generic line draw routine. If you called a method to change any parameters of the line (dashed, color, thickness, …) that method would rewrite the line draw routine.

    I suppose this is a matter of taste, but most systems that use RS-485 in the military world use it because it allows for a multidrop system with limited number of wires. In such systems it is important/critical to know if you have had a bus collision. For this reason, the receiver is always left on. When you transmit, you read back what you wrote. If they are the same, great; if not, you had a collision and must rebroadcast. Very similar to Ethernet.

    If in the commercial world RS-485 is only used for single duplex single master to slave setups then their implementation is fine. Otherwise I contend they have their heads in a dark place.

    Not that Sparkfun reads these comments (its been two YEARS since I posted), but if they do, I would suggest the next revision of the board include a solder jumper to allow for a “receiver always on” mode. By default it would connect the /RE and DE as right now. Add or remove the solder jumper and the recieve enable would be enabled and the transmit enable would go back to the micro. Should only add the cost of one resistor and a bit more copper.

    As for considereing other options, I would love to, but I am dictated by my customer. Its been a while, but I think I was able to lift the receiver enable pin and tie it appropriately.

    Please stop trying to be cute with the video transitions. All the pulling of focus and panning into products is making me nauseous! Straight cuts work very well and look more professional.

    I think the 7mm dia output shaft is also in error. I think the bronze bushing is 7mm and the shaft is 3mm from the datasheet.

    1) Would anyone care to guess how high the SparkFun building is? Would like to know to estimate the GPS error due to building masking.

    2) Could an email address be established for submitting AVC questions? Answers that would seem of general interest could them be posted on a read-only thread on the Forum. This would be a better and more formal solution than posting to this comment list.

    Ok,… your crazy.

    Last I looked I had 3000+ “unread” emails. I would need at least 12 LEDs!

    Take a lesson from your “snap apart” line. Put the mounting holes on one/both ends of the board and perforate it so they can be snapped off if size is what you want.

  • News - New Product Friday: A Dat… | about 3 years ago

    Mounting holes on the rotary breakout board! How novel…!
    (Mounting holes should be standard on ALL your boards. Even if they are just big enough for one or two 2-56 machine bolts.)
