I am planning to replace the Oncore GPS receiver in my NixieSat clock with a Haicom HI-204III puck-style receiver. Given that Jeff Thomas is no longer with us to provide updated firmware, I believe that I will have to:
1. Install the MAX232 transceiver chip and associated capacitors. 2. Continue to use the 1PPS signal from the new GPS receiver. 3. Program the Haicom unit to only output the $GPRMC string using the SiRF demo program. The manual on the Haicom puck describes both a 1PPS signal and a "1PPS valid" signal. However, neither of these appears on the 5-pin miniDIN connector from the receiver. In searching various Haicom literature, I believe these signals appear on pins 5 and 6 of the 6-pin interface header that the din cable is fed from in the Haicom receiver. Questions: --Has anyone done this Haicom conversion without new firmware in the clock? --Am I correct about the signals on pins 5 and 6 of the header? --Does anyone know the manufacturer and part number of the female 6-pin connector that mates with that header?
