He issued a firmware update some years ago. Firmware 040604 (that's MMDDYY) and earlier require a receiver with a 1PPS output. Firmware 11xx05 and newer uses the start of the $GPRMC string as the reference. Roughly, this means that if you have a firmware version that incorporates the "DST fix" for 2005 and newer, you can use any receiver. The firmware was shipped on pre-programmed microcontrollers, so you'd need to find one of those (or someone who has the firmware binary) in order to update. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
