F E A T U R E S

Simple, reliable operation. With the 440A BTR, part programs are stored on computer disk and may be load or run directly from the computer, reducing both set-up and programming time. Punched tape is completely eliminated, along with the associated storage, handling and maintenance problems.

Easy to install and use. The 440A BTR is installed inside the NC cabinet and connected to the NC's tape reader port. This means that virtually any NC with a tape reader can be easily upgraded for direct program and executive loading as well as drip feeding.

Reader and puncher emulation. Bi-directional transfers are supported for NC/CNC machine tools equipped with both a tape reader and tape puncher port. In addition to loading files into the CNC memory, edited programs may be saved back to the computer. The 440A BTR includes support for Facit parallel and RS-232C and current loop serial punch output ports.

Full support for CNC executive software loading. The 440A BTR may be used to load CNC executive software directly from the computer. What's more, the 440A BTR includes a unique 'Transcribe' mode that lets you transcribe tapes to disk files using most standard tape readers.

Unlimited program size. The 440A BTR includes 256Kb of memory (2184 feet) of onboard program storage with battery backup. For larger files, the 440A BTR may be used to 'drip feed' a file from the computer.

Data echo ensures accurate loading. For the ultimate in accuracy and reliability, the 440A BTR can echo data back to the computer for precise verification of program loading. In fact, this unique feature of the 440A BTR lets the host computer control and monitor every aspect of program loading. For operator convenience, the computer displays the program as it is read by the NC and a bar graph indicates progress.

Complete system. The 440A BTR includes everything you need to get started right away, including a free copy of the Dostek DNC BTR Edition software and a cable to connect the BTR to your computer.

Low in cost. Prices start at only $795 for prepaid orders.
