Overview

One uplink, one serial port, no surplus features

The T300-310 is the model most of our distributors stock first. It is a 4G router with two Ethernet ports and a serial port in a metal housing that fits a DIN rail — the smallest useful set of interfaces for a metering cabinet, a pump station or a single machine.

The serial port is the reason this model sells. RS-232 / RS-485 on the terminal block reads a Modbus meter or talks to an older controller directly, so the project does not need a separate serial-to-IP converter in the panel. The two Ethernet ports cover one local device and the wired uplink.

It weighs 152 g and measures 94.1 × 78.2 × 25.1 mm, so it can be mounted inside equipment where a larger router will not fit. The DC 12–24 V input matches the control-panel supply already on site, and the −20 °C to +70 °C range covers an unheated cabinet. Configuration, branding and final inspection stay with our own team on every order.

The serial port, done properly

RS-232 / RS-485 on a pluggable terminal, so a meter or a legacy controller connects without an add-on converter.

Small enough for equipment

152 g in a 94 × 78 mm housing — it fits inside the machine, not just beside it.

Stocked as a volume line

The model distributors order in the hundreds; component stock covers 1–2 months of demand.

GNSS positioning with RTK — optional module

Optional · confirmed with the quote
  • OptionalA customizable GNSS module can be fitted at order: RTK-capable, using GPS, GLONASS, BeiDou, WAAS, EGNOS, MSAS and GAGAN as a mixed engine. It uses the dedicated antenna port on the housing, so position and time reference come from the same box as the uplink — no second device in the cabinet.

Wanted for positioning, timing or RTK-corrected location — mobile plant, survey vehicles, time-synchronised cabinets. Add the GPS option to the model code and we confirm the matching antenna with the quote. Ask our team →

Regional versions

Tell us the market, we confirm the band version

4G band plans differ by market. Send the destination country and we will quote the matching regional version — this is the first question most distributors ask.

EA / AU

Band plans for Europe, Asia, Africa and Australia — the mainstream 4G networks.

NA / SA

North and South American band plans, including the 600 MHz and AWS combinations.

JP / GL

Japan- and global-version band plans for networks outside the mainstream groups.

Applications

Where this model is deployed

Typical uses reported by distributors and system integrators working with this model.

Electricity and water metering

RS-485 reads the meter directly and the router forwards the readings over 4G — no separate gateway in the cabinet.

Pump and lift stations

Two Ethernet ports for the local controller and one 4G uplink, at a size that fits a small enclosure.

Machine and equipment OEM

Fitted inside the machine for remote service access; 152 g and IP30 metal housing.

Solar and battery sites

Low power draw and a wide 12–24 V input for sites fed from a DC bus.

Building services cabinets

Serial link to the BMS controller, Wi-Fi for commissioning, 4G for the backhaul.

Volume distribution

The model distributors reorder most often — component stock covers 1–2 months of demand.
