Hamation Bandpasser AS-419

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 ?

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






Hope this helps.
