Versions of these oscillators prior to firmware version 1.96 had a user programmable DDS in them that could generate up to 20 MHz on pin 11 of the DB25 connector.   All references to  the commands to program this output have been removed from the current documentation.   Does anybody have any info on how to set the user DDS frequency?
