You make one!
I have a Zebra printer that uses a serial cable. I am wanting to play with it with an Arduino. The cable averages $40.00. Since I only paid $5.00 for the printer and not sure what I will do with it, I decided to make my own. The connector is not standard and the closest one I think would work is $6.00 quantity one and would be gamble.
Here is the connector
The first hurdle was finding pins that would work. I found a few connectors in my junk drawer that the pins fit. I removed the pins from the connectors and soldered them onto wires.
I then covered the connector in the printer with blue tape.
Used a pin to poke holes
Used a piece of overhead projector transparency to outline the socket. (remember those?!)
Added the pins
Filled in around the pins with lots of hot glue and then removed.
Since it will not be inserted and removed often, it should hold up for what I need.
