I accidentally dragged a bracket moving the scale causing the glass to brreak.

I read somewhere you can just repin the serial port wires on some models.

Anyone have any advice on this?

Look up the scale that you have at Acu-Rite, it will show the output connections for the scale, match that to a new glass scale. I did a basic check of the Acu-Rite newer glass scales to a Chinese model and the DB9 pinouts were different, so one would need to probably buy a new DB9 plug and make the revised connections or buy a set of male/female plugs and make a short conversion cable. There might be an adapter cable but they run almost as much as a new scale (H&W Machine Repair lists some). You could also call there Acu-Rite tech. support as to comparability of scales, but most likely they will do this for products they sell. Unfortunately an Acu-Rite scale will cost more than a whole new DRO package these days.
