Looks for Range

Looks for Range (1/11)

  1. It does. I already tried all of those things and still no joy. Just making sure I didn't miss anything. My USB module is a cheap Chinese Prolific knockoff I picked up on eBay but it look identical to the Amazon link shown in the first post of this thread. I also tried the USB plug from my handheld ham radio with and without the resistor. It too transmits fine, but also no receive. I'm not sure at this point if I should spring for another USB module, another Pro Chrono, or just forget about it. I guess the best/cheapest route would be to build another cable first using a known good module. Anyone have a link to a tested FTDI chipset module? Ryan
  2. Ok, I can't get my cable to receive from the Pro Chrono even with the resistor. I tried different values (4.7K and 20K) and still no deal. I can change the string from the computer fine, so I know I can talk to the chronograph fine. If I connect the Rx and Tx lines together on the cable end that connects to the chronograph everything bounces back in HyperTerminal so it appears the usb/serial cable is working fine. I've tried two computers (XP, Vista both Dell) and it made no difference. Anyone have any thoughts? Could it be something defective in my Pro Chrono? I hate to buy/build another cable only to find out my chronograph is defective. Ryan
