Setting Up Your BG Micro VFD

Page: 2/3
The Soldering

The first part we are going to work on is the serial cable. This is what data is transferred over between your machine, and your VFD. The first step is to get your bare serial connector (often referred to as a DB9 connector) ready.

We need to solder a wire to the center pin on the top row of pins. The diagram below explains this in greater detail.

The pin in bold is the pin that you need to solder the wire to.

After that is completed, the next step is to solder a connector on the other end that will connect to the pins on the VFD. For this, I recommend the plugs that come with your standard ATX case. These are the same connectors that hook to your motherboard and power LED?s, and hook up switches/restart buttons on the front of your case. I just snagged a couple of the two pin connectors from an old case I had lying around, and I recommend you do the same.

Once you?ve gotten your connector from an old case, take the wire that you?ve soldered to the DB9 connector, and solder it to one of the wires on the connector you?ve taken from your case.

Now we must do the same thing to power our VFD. We will need a Molex connector and another two pin connector. Solder a wire from the two pin connector to the 5 volt pin on your Molex connector, and one wire to your ground pin.


Placed on the back of the VFD are a set of jumpers. You?ll want to set these in the correct position before you start displaying info on your VFD.

Your first jumper should be set to ?19200?, your second jumper set to ?Intel?, and your third jumper set to ?Norm?.
