The MERLIN Behind-the-Tape Reader (BTR) is an affordable RS-232C serial port retrofit for older NC/CNC machine tools. The BTR replaces the machine’s tape reader, letting you integrate your older machine tools into a modern DNC system. The BTR simplifies operation and reduces set-up time by letting you load part programs and executive software directly from your computer.
Product Features
Simple, reliable operation. With the 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 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 BTR includes support for Facit parallel and RS-232C and current loop serial punch output ports.
Full support for CNC executive software loading. The BTR may be used to load CNC executive software directly from the computer. What’s more, the BTR includes a unique ‘Transcribe’ mode that lets you transcribe tapes to disk files using most standard tape readers.
