FT - BTR

Fault Tolerant Behind-the-Tape-Reader Interface

FT-BTR is a full-featured, industrial grade, low cost BTR (Behind the Tape Reader) with data I/O via a “fault-tolerant” data packet based protocol via an RS-232 link. Used with CCI’s SuiteDNC and Terminator software for full database security and remote administration. Also works with our legacy products DNC500 and DNC1000.

Features

BTR interfaces available for virtually any N/C or CNC controller.

  • Fault-Tolerant data packet based protocol via RS-232 guarantees error free data transfer.
  • 512K memory standard with storage for the equivalent of more than 3000 feet of tape.
  • Infinite tape length support via revolving buffer.
  • Built in serial and parallel (FACIT) ports for uploading from CNC memory.
  • Connection for optional external LED and Reset, Rewind and Tape/BTR switches.
  • 24 LED’s for status and troubleshooting.
  • Supplied with aluminum enclosure and external power supply module.

Motherboard Jumpers

* Factory Defaults

W1A* / Run signal from the NC/CNC is a level. Most controls are this way. Remove jumper from W1B
W1B / Run signal from the NC/CNC is a pulse. K&T controls are this way. Remove jumper from W1A
W2 / Puts +5 volts on the Facit punch input connector, J5 pin 24. For some older Fanuc CNC’s.
W3A* / Puts a 470 ohm resistor on the Facit Punch input connector, J5 pin 12, Punch Ready pulled up to +5 volts. Remove jumper from W3B.
W3B / Puts a 1.5K resistor on the Facit Punch input connector, J5 pin 12, Punch Ready pulled up to an externally applied voltage on J5 pin 23. Remove jumper from W3A.
W4* / Connects a .0022 noise filter capacitor between Facit punch input connector, J5 pin 11 and Signal GND.
W5 / Makes the Serial In signal available to personality cards. Special use only.
W6 / Makes the Serial Out signal available to personality cards. Special use only.
