  • Convert Tohnichi output format to a wide variety of protocols in your network. You can select from four protocols, including Atlas Copco Open Protocol. TPC model: ACOP serial / ACOP socket / Stanley / Custom TPC2 model: ACOP serial / ACOP socket / ToolsNet / Custom
  • Can convert to protocols you are using in your network. Tell us your protocol specifications for us to match specific requirements.
  • Can tag timestamps on tightening data. The built-in clock maintains the current time, so the device can add time-relevant data to output formats.
  • Receive VIN data by connecting to a barcode reader. Has two COM ports, permitting concurrent use with a barcode reader.
  • Can be connected to two different Tohnichi products. Has two COM ports, permitting connections to two different devices.
  • RS232C <=> Can be used as an Ethernet converter. Input data can be output without requiring protocol conversion, using RS232C-to-Ethernet conversion functionality.
  • Attachable on 35-mm wide DIN rail. Easy attachment for use in varied work environments.


  • Custom made protocol option: Specify your protocol specifications to learn possible options. Please consult Tohnichi in advance regarding the use of special protocols.
  • For models with the CEM3-G-BTA name suffix, the TPC version must be 1.20 or higher, or the TPC2 model must be used.
  • To connect directly to a model with a CEM3-G-BTA suffix or to the PTA-G-BT, a Bluetooth® enabled receiver for converting to RS232C should be purchased on the open market.
  • Comes with a backup battery to maintain the current time when not connected to a power source.
  • The BA-8W AC adaptor is required for converting AC 100V to 240V.
