Modbus TCP/IP Data Box — Modbus RTU gateway with RS‑485 and USB‑C for Microtech instruments

Modbus TCP/IP Data Box provides a compact gateway to integrate Microtech DataMet instruments into industrial Modbus networks, converting USB‑C output into a configurable RS‑485 Modbus RTU interface for data collection and automation tasks

• Industrial Modbus RTU interface (RS‑485)
• Compact IP40 housing, 53×82×31 mm
• Configurable baud rate, default 9600 bps
• USB‑C compatibility with DataMet instruments

Reliable serial integration for automation and data logging

The device converts a USB‑C output from measurement instruments into a standardised Modbus RTU protocol over RS‑485, enabling direct connection to PLCs, data loggers and SCADA systems. With a configurable baud rate (default 9600 bps) and fixed settings of 8 data bits, 1 stop bit and no parity, the unit simplifies serial configuration and reduces commissioning time. This stability ensures consistent data transfer for production monitoring and traceability.

Small footprint, robust connection in controlled workshops

Housed in an IP40 enclosure and measuring 53×82×31 mm, the unit is designed for neat mounting near measurement stations where protection from large particles and light contact is sufficient. The compact dimensions and low weight make it easy to integrate into instrument racks or control cabinets without requiring additional space. The modest protection class suits many indoor industrial and laboratory settings while keeping wiring runs short.

Clear operating window and environmental limits for dependable operation

Rated for operation between 5–40 °C with up to 70% humidity, the interface is intended for typical workshop and laboratory conditions rather than harsh outdoor environments. Specifying these environmental limits helps planners choose appropriate locations and enclosures so the interface maintains reliable communications and long service life. The device is supplied without a measuring instrument and is intended to be paired with Microtech DataMet series equipment.

Practical protocol and wiring details explained

The RS‑485 output is a four‑wire arrangement (5–24 V, GND, A, B) commonly used for industrial Modbus RTU networks; this ensures galvanic reference and signal integrity across longer cable runs. Explaining the wiring and protocol behaviour reduces installation errors and supports predictable system behaviour during commissioning. The gateway converts USB‑C instrument data to a widely supported field protocol, enabling legacy systems and modern controllers to share measurement values without bespoke drivers.

FAQ

What does the gateway do in a measurement setup?
The Modbus TCP/IP data box converts USB‑C output from a Microtech DataMet instrument into a Modbus RTU stream on RS‑485, allowing PLCs and data loggers to read measurement values directly.

Which serial settings are used by default and can they be changed?
Default serial settings are 9600 bps, 8 data bits, 1 stop bit, no parity; the baud rate is configurable to match the host system.

Is the device suitable for outdoor or wash‑down environments?
No; the unit has IP40 protection and is intended for indoor workshop or laboratory use within the stated 5–40 °C and 70% humidity range.

Does the product include the measuring instrument or calibration certificate?
The delivery is without a measuring instrument; calibration certificates are not included with the data box unless explicitly stated for the paired instrument.

What wiring is required to connect to a PLC?
A four‑wire RS‑485 connection (5–24 V, GND, A, B) is required; the gateway appears on the Modbus network as a standard RTU device for polling.
