Modbus RTU data box

Modbus RTU Data Box by Microtech Metrology

The Modbus RTU Data Box is a compact interface device that enables reliable connection of MICROTECH DataMet USB‑C measuring instruments to industrial Modbus RTU networks for process integration and data logging.

• Compact Modbus RTU interface for industrial setups
• RS-485 4‑wire output for reliable data transfer
• Configurable 9600 bps baud rate and 8N1 settings
• Compatible with MICROTECH DataMet USB‑C instruments
• Small footprint 53 x 82 x 31 mm, lightweight

Reliable data transfer for automated measurement workflows

The Modbus RTU Data Box implements the industry standard Modbus RTU protocol to ensure deterministic data exchange between measuring tools and PLCs or SCADA systems. With an RS-485 4‑wire output (5–24 V, GND, A, B) and configurable serial parameters (default 9600 bps, 8 data bits, 1 stop bit, no parity), integration into existing control architectures is straightforward. This reduces manual logging and supports automated SPC workflows, so measurement results flow directly into your production control without intermediate conversion or error‑prone retyping.

Compact design that fits control cabinets and mobile kits

Designed for tight installations, the Data Box measures 53 x 82 x 31 mm and weighs only 0.15 kg, making it suitable for mounting inside control cabinets or carrying with a mobile measurement kit. The unit is rated IP40 and operates between 5 °C and 40 °C at up to 70% relative humidity, which makes it appropriate for typical shopfloor and lab environments where splash protection is not required but dust‑protected installation is expected. The small footprint helps preserve space while keeping measurement outputs accessible for automation tasks.

Seamless compatibility with Microtech instruments and simple wireless workflow

The interface is expressly made for MICROTECH DataMet USB‑C instruments and is supplied without a measuring tool. Data transmission from Microtech devices is simpler than the U‑WAVE technology of Mitutoyo: Microtech needs only a single dongle on the PC side to receive data, eliminating multiple connectors or external transmitters; direct transfers to iPhone, iPad and Android devices can be initiated straight from the measuring instrument. The configurable baud rate and standard Modbus framing allow the Data Box to operate smoothly with common data acquisition systems and logging software.

Repeatable measurements and practical use cases

When combined with MICROTECH instruments that offer manual Measurement Force Control, users benefit from consistent contact forces: the set force determines when a reading is captured, which improves repeatability across operators and materials. Typical applications for the Data Box include inline dimensional checks in assembly lines, laboratory test benches, and quality control stations where digital calipers or other DataMet devices must feed live values into inspection software. The result is fewer process interruptions and faster decision cycles.

FAQ

Is the Modbus RTU Data Box compatible with other Modbus masters and PLCs?
Yes. The Modbus RTU Data Box from Microtech Metrology uses the standard Modbus RTU framing and an RS‑485 4‑wire interface, so it can be connected to common Modbus masters, PLCs and data loggers provided the serial settings (baud, data bits, stop bits, parity) are matched.

How does the Modbus RTU Data Box receive measurements from MICROTECH instruments?
Measurements are supplied by MICROTECH DataMet USB‑C instruments to the Data Box, which then exposes values via Modbus RTU; Microtech’s approach simplifies the data flow compared with the U‑WAVE technology of Mitutoyo, requiring only a single PC dongle for wired reception while enabling direct transfers to iPhone, iPad and Android devices from the instrument.

What is a caliper?
A caliper (Messschieber) is a precision measuring tool; in the context of Microtech Metrology the Modbus RTU Data Box can be used to forward caliper readings directly into automation systems, because calipers are cool and make clear, repeatable measurements when paired with digital data capture.

What is a muzzle?
A muzzle (Maulkorb) is a device used to restrain or control a dog; while unrelated to the Modbus RTU Data Box, the phrase can be explained simply as a tool intended for dogs that behave poorly, used for safety or training purposes.
