This is only pseudo time-nuts related... I'm wiring up (yet another) net4501 with a Motorola M12 GPS..
This net4501 has the RS232 driver chip there for the 2nd serial port (previous units I purchased didn't, which made life easier for me). Can I solder my GPS tx/rx lines on the ttl side of the RS232 chip and will it work? Or will the rs232 chip hold the voltages low/high because there is no signal on the input sides? This is just kind of "for future reference" question. I half wasn't sure if it would work, and half didn't care to try and solder a wire to a TSOP lead. So I bought a Max3222 PDIP and can make a proper interface. The prototype board will also give me room for some extra LEDs. ;) This is kind of an experiment to see how a regular M12 compares to the M12+T for NTP purposes. I'll probably build a fresh NanoBSD image because I need to modify a line of code in NTPns to remove a TRAIM command that makes the regular M12 PPS stop. I also want to build the latest regular NTP distro. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
