Advanced Serial Interface converter (BTR)
Converts your older CNC/NC
Machines to an RS232c / serial
interface.

Rapid program transfer without Paper Tape Limitations. Programs can be transferred directly from a computer system at rapid speeds of up to 19200 Baud. The advanced SIA is maintanance free and simple to install. The substantial BTR memory (1 Mbyte) enables large programs to be held or "drip fed" as determined by the controller, greatly increasing operating speed. Comprehensive facilities include code conversion, file handling and management, automatic file recognition and many other features. The LCD display allows the user to see the configuration, operational mode status and data transfer.
