Hi I seem to have a lot of experience running Rb’s without heatsinks. No matter how many chickens I sacrifice at the full moon, the results seem to always come out the same. If you don’t get the temperature of the internal baseplate down under 40C (with a heatsink and maybe fan) they die.

Hello group, I have significant progress with generator. And there were new questions :-) Frequency was little bit higher than 10 MHz - after correction of PLL constants SP and MO now is just on spot. In documentation is not clear described what is active state of signal 1PPS_IN. I found that

Hello Hal, Thank you very much! You was right! One additional inverter in both line (Rx and Tx) between PRS10 and USB2Serial fix issue with communication. Best regards Philip Sent from my iPhone > On 4.03.2016 г., at 11:43, Hal Murray wrote: > > >> As I already

You could try « RC 1 » blind. That will reset the EEPROM values to factory settings. However I do not see any settings for serial rates, so it may not help. >From your oscilloscope, it should be possible to determine stop/start and baud >rate and decode the binary data. I have done this in the

Hi Jarl, As I already write PRS10 is configured as serial communication. With oscilloscope I can see serial signals, but when enter this signal in computer with TTL level USB2serial converter all information is repeatable character unknown for me and not as described in manual. For test i
