You are saying you want to use a USB cable instead of ethernet cable, etc. Well if that's true just chop off both ends and wire it up. No big deal. I think what you want is a USB enocder. The part you want modular is the USB cable instead of how you have it now, ie the button, etc connections are modular. You'll need a seperate encoder for each panel. Is this what you were talking about? |

If I have to do it with 1 encoder per panel, that gets expensive, and may not work anyway. I'm trying to just keep each panel down to 1 connection, and I like USB cables, so I'm idly curious about using USB cables as a connection. I could get into the specific reasons why I want to use USB cables, but it's not that important. The problem with just cutting USB cables... I didn't think they were color coded on the inside, so using them to make multiple swappable panels would be difficult. I thought there might be some kind of cheap pre-coded cable or usb interfacing board or something out there already made that I don't know about. |

USB Cables are color coded Red, Black, White, and Green. |

Technically, It isn't a requirement for the system to work and it will probably be fine without it. It is a shield used to block noise on the power, gnd and signal lines. Some enclosures will have more noise then others. Also, I think most of the USB devices are low speed so that may help, High-speed and Full-Speed devices would be more susceptible to noise. Not having a 5 meter run to the PC would help and having a short run after the modular part would help. I definitely wouldn't do it for a removable hard drive, but for this application it probably will be fine. Make sure the shield doesn't touch any other wires. I'm more worried about not attaching GND first, but I have a really low threshold for this. I should probably get off my soapbox for this, but my customers are really dumb. ::) |
