Hello,
I just got a Profusion RA-FX16G digital effects module for guitar amps, and along with it a Belton Digital Rotary switch BTDS20. The datasheet indicates which pin numbers to use when connecting the board to the switch, but there are no markings on the switch as to which pin is which. There are 8 pins on the switch and one digital ground. Nowhere on the switch data sheet does it give pin number identifiers. It's a 4 bit grey code switch. Is there some pin numbering standard?
Anyone tried this module? Has 16 different effects, costs about $30 plus $5 shipping from the UK. I want to experiment but how do identify the switch pin numbers?
