[GPS_Standard] Version 4 of VE2ZAZ GPS Standard firmware released

[Bert, VE2ZAZ]

Greetings,
 
As promised, I have just updated my website with a new firmware version for the VE2ZAZ GPS-Derived Frequency Standard. Version 4 (v4) adds the following features:
 
- An Alarm Latch clear push-button feature which allows to clear any latched alarm without having to log on to the system via RS-232C. Grounding pin 22 momentarily will clear the alarm latch.

- A 10MHz/5MHz OCXO rate selection based on the state of pin 21. High (default, floating) state is 10MHz, Low (grounded) state is 5MHz. Pin state is sensed at power up only.
 
Other than these two additions and some clean up work in the assembly source file, no other feature was added and no changes were made to the FLL algorithm. 
 
Please visit my website for more detail. http://ve2zaz.net/GPS_Std/GPS_Std.htm
 
Best Regards,
