| help with USB Zero Delay Encoder over long wire |
| (1/3) > >> |
| bimm25e:
So I have MY Zero Delay USB encoder hooked up through a cabinet and the encoder is about 24" away from the buttons, the distance puts too much of a strain on the device and it craps out if you hit a button. Is there some way I can alleviate this without shortening the wires? perhaps there are some type of capacitors I could put in line near the power source? |

The length has nothing to do with it since a standard jamma harness is much longer and works fine. I saw you mention your issue in your switching thread. Are you completely lifting ALL power to the naomi system along with ground connections when in your "pc" mode? good day. |

I ran every connection through the switch... but unplugging the Naomi side snap connectors fixes everything. i'm quite confused now... I'll put up pictures tomorrow. |

Any chance that some of the poles aren't normal double-throw connections? Maybe some poles were designed to be constantly connected to both throws for ground (or power?) to avoid spikes/surges while switching. To eliminiate that possibility, check for continuity between A1/B1, A2/B2, etc. using the labelling pattern on the DPDT diagram below. Scott |

What is the wiring diagram of the ZDE? I couldn't find any wiring schematic, the only pictures I can find are of a PCB with a blob and the "plug in" wire look like they're paired up (two wires for each switch). This leads me to think that it's possible that the switches don't use a true ground as a reference for the switches like the Naomi board does. For example, I've come across some controllers that supply 1/2 voltage on a common rail so analog sensors can detect a +5 or a 0v condition. This allows one pin to sense two switches at the cost of ghosting. You also might have a short somewhere in your wiring. I think you said both boards are segregated through the switch. But how can the be if removing the Naomi board fixes your problem? |
