Hi Mike,
I finally found a way to program the clarifier offset via the CAT
interface. There were a few issues that caused the problem described
in my previous email.
1.) data1 byte needs to be set to 0xff in order to enable
tuning of clarifier offset. Other values won't allow tuning.
2.) The translation of a frequency into khz (data3) and hz (data4)
isn't quite as obvious as it is presented in the user's manual.
The values passed into the command packet need to be BCD encoded.
3.) The data4 byte represents the value in 10's of Hz, e.g. 100Hz
would become 0x10.
4.) data3 and data4 represent the value of the desired total offset and not
a stepping value.
Here an example that shows how to program a desired clarifier offset
of +1420Hz and -1420Hz:
offset|opcode | data1 | data2 | data3 | data4
----------------------------------------------
+1420 | 0x09 | 0xff | 0x00 | 0x01 | 0x42
----------------------------------------------
-1420 | 0x09 | 0xff | 0xff | 0x01 | 0x42
----------------------------------------------
Note the BCD encoding for data3 and data4 byte!!!
I hope this helps,
73, Berndt
