Hamation Bandpasser AS-419

mlstutler

Is anyone using the Hamation Bandpasser AS-419 filter with their Flex Radios?  The documentation is a somewhat confusing.  I am reading that you have to raise 12vdc to the pin on the remote input to switch bands.   I don't see how this can work if the FTDI USB to parallel interface only supply's 3.3vdc. 

thanks.

I found a level shifter that can be used if the AS-419 requires a 12vdc input.

Update - We purchased the Bandpasser and realized that BCD can also be used to control the unit.  Took about 5 minutes to configure and it works with no issues.

Hi Mike, can you use BCD right into the bandpasser from the USB cable ?

mlstutler

Yes that is what we do.  Here are screen shots of the config.






Hope this helps.

Please supply the wiring color code to the mouser cam shell FTDI USB unit. I can't get the correct wiring code to make the AS-419 to work.

Mike, your the man, Thx..
When you have the letters, I have numbers on my FTDI USB unit cam shell that I **** the colored wires into. Would A=1 , B=2?
Plus its a DB-9 for the AS-419
Thx

David - Did you get answer to the pin mapping? I'm looking for the same thing. Andy NA4DA
