Product overview

A 4G industrial router for centralized access to multiple Ethernet devices. Four LANs plus one equipped WAN, could reduce the number of small on-site exchanges and retain the teleport capability.

The procurement staff will look at these three points first.

Whether to match the sceneClear list of equipment points, number of interfaces and version of the protocol to avoid selection based solely on product name.

Full scope of procurementAntennas, power, SIM/APN, mine protection, cabinets, platform access, solidware and authorization are also identified outside the mainframe.

Basis of acceptanceThe contract contained order codes, hardware interfaces, cellular modules, protocol versions, test points and random documents.

Data links and working methods

On-site instrumentation, PLC or sensor, through Ethernet, serial or I/O access, equipment completes transmission, protocol conversion, cache or edge processing, and is sent to SCADA, integrator software, MQTT platform or operating system via 4G/5G or cable network. Stability depends on the design of a table of points, a round of interviews, network coverage, a bridging strategy and a platform interface.

Core advantages

Up to 5 LAN mouths for PLC, HMI, camera and instrument mix access
Wireless and 4G can be used as a link back up.
Serial, Wi-Fi and TF storage by project

Usage scenarios

Remote maintenance of workshop equipment
Self-help terminals and financial equipment networking
Multi-equipment cabinets and small station rooms

application benefits

Construction valueReduced fragmentation converters and duplicate wiring and centralized management of on-site equipment access, network transmission and remote maintenance.

Run ValueReduction of data gaps caused by temporary break-nets through chain testing, local caches and break-points.

Operation and maintenance valueRemote view of status, configuration and upgrade to reduce the number of on-site screenings at remote sites; key changes still require the retention of version records.

Selection guide

Statistics on the number, speed and need for independent switches of Ethernet equipment that needs access.
Identification of single SIM/BiSIM, Wi-Fi, TF cards and serial combinations cannot be based solely on base model.
Check VPN type, centre-end equipment and certificate/key management.
Video or large-flow uploading projects should account for 4G bandwidth and flow fees on a physical and combined basis.

specification range:This model addresses multiple port networking and base data forwarding and is not equivalent to a programmable edge calculation gateway. If complex protocol conversion, logical operation or Docker application is required, TG465 should be transposed.

Key points for installation and commissioning

Power supply, grounding, mine-protected and antenna position checks are completed and access to on-site equipment is completed; communication lines are separated from power lines.
The validation station number, Porter rate, validation place, repository and data unit by point, with local access to the platform.
Set collection cycles, reporting cycles, caches and catch caps, and simulate off-grid, off-power and off-site scenarios.
Maintenance of configuration, solid version, SIM/APN, protocol mapping and acceptance records after shipment to facilitate subsequent replacement and traceability.

Procurement and Technical Confirmation Checklist

FAQ

What is TR341 for?

TR341 is used mainly for a 4G industrial router for centralized access to multiple Ethernet devices. The selection shall first confirm the on-site equipment, interfaces, protocols, network and power supply, rather than be based only on 4G or 5G names.

Can TR341 access PLC, instrument or sensor?

Yes, but with actual interfaces and protocols. The reference interface is 1xWAN+4xLAN (can be set as LAN), RS232 and RS485, TF cards are optional; if private PLC agreements or exclusive statutes are involved, a list of equipment and a contact list should be provided.

What communication protocols are supported by TR341?

Reference agreements include TCP/UDP Express, MQTT, Modbus RTU/TCP, IPsec/OpenVPN/L2TP/PPTP. Some industry agreements, platform plugins or secondary development functions may require the designation of solids, with the version, authorization and delivery to be confirmed prior to ordering.

Can the 4G/5G version of TR341 be used directly by the three main domestic operators?

Requires confirmation by specific module and order code. Product lines may include different national/regional bands; domestic projects should check mobile, connectivity, telecommunications frequency bands, SIM/APN, on-site coverage and local access requirements, and should not substitute “global frequency bands” for an optional identification.

Could TR341 be installed directly outdoors?

The reference environmental condition is IP30, -35 ~75°C, with a relative humidity of 93% ± 3% without condensation. The IP30 product should be installed in containers with water, dust, mine and temperature-control conditions and cannot be used as outdoor water protection equipment.

What information is required for request TR341?

Please provide a list of the points of equipment, the number of interfaces, protocols and repositories, the collection and reporting cycle, the central platform, the cellular operator, the power supply, the installation of the environment, the requirements for remote maintenance and the selection functions required.

Ordering instructions

This page does not write optional features into standard configurations. In cases involving cellular bands, industry regulations, State secrets, secondary development, certification or platform authorization, a written confirmation of the corresponding version must be obtained prior to the next list.
