I bought two TAPR ThunderBolts and on one of them the serial port would quit communicating after a while. There was no response to any command, only removing the power and then restoring power would get it talking again. My power supply was okay. I opened the T-Bolt and inspected the solder connections but didn't see anything suspicious. I didn't do any further troubleshooting because my third T-Bolt from Fluke.L arrived and the Fluke.L T-Bolt has been working fine.
NOTE: If you boot Windows with your ThunderBolt connected to the Com port, Windows will think it is a serial mouse and grab the port. It can lead to some interesting Windows behavior as the T-Bolt outputs data. Mike - AA8K On 11/01/2010 08:36 AM, Adam Feigin wrote:
Has anyone ever repaired a Tbolt which exhibits the "dead serial port" phenomenon? I've seen a couple of people post about their Tbolts being "dead" in this manner, ie the serial port gives no output, and doesn't respond to any input, but the 10Mhz and 1pps outputs work. Seems a shame to pitch it. Just wondering if anyone has managed to bring theirs back to life, and if they did, how.
