Re: Older Bridgeport DRO help needed!

Sorry to tell you but the Textron and the Teledyne cannot be mated.
The signals are totaly different and the line counts are different.
You will need to find another Textron scale to use with this system.
Ebay has some dro system system and that may be you best bet.
