We are currently using the Centrum Research tape reader emulator to transfer NC data from our PC network to our drills (2) and router. Are there any affordable systems that would allow us to bypass the reader and directly connect the machines? Our present system has generated a couple of drill errors lately, so we are looking for a more reliable way to transfer the drill data. We have 2 Excellon CNC4 controllers and a CNC6. Thanks for any help you can provide!
