I am assembling a data cable for firmware programming and retrieving data. The Digi-Key part is 768-1029-ND shown here
I solder this to a 7-pin round DIN, CP-1070-ND, shown here:
The only other components I need are a 1 k Ohm resistor and a 4.7 V Zener diode. I was unable to find a Zener in stock so I’m hoping someone can help me select one correctly.
Let me know if you need any additional information
