The TR323 5G/RedCap dual-Ethernet industrial router offered by METRAVON provides two Gigabit Ethernet connections and two RS485 ports in a compact enclosure. Cellular choices include 5G SA/NSA or RedCap configurations with module-specific 4G support. Select the radio version for the intended service and workload, then verify the local port arrangement and serial operating mode.
State the communications requirement before choosing 5G
A charging cabinet sending periodic readings has a different requirement from a mobile unit carrying video. Define the useful data rate, tolerated interruption and response-time target at the application, not merely the preferred network generation. Test with the operator and subscription that will be used at the site.
For mobile equipment, include the actual travel route, antenna position and coverage transitions in the trial. A successful stationary test beside one cell is not evidence of continuous application service throughout a moving route. Machine safety and time-critical motion control need a separately assessed arrangement.
TR323 ports and enclosure
| Item | Listed data | Selection check |
|---|---|---|
| Ethernet | 1 Gigabit WAN/LAN; 1 Gigabit LAN | Assign local and upstream roles and confirm the required addressing and routing behaviour. |
| Serial | 2 RS485 | Identify whether the router transports existing requests or performs a supported data-conversion function. |
| Debug | 1 RS232 | Keep this service connection distinct from permanently available instrument ports. |
| SIM | Dual-SIM option | Specify the offered arrangement and switching policy; two SIMs do not prove simultaneous active links. |
| Size / supply | Approx. 104 x 78 x 24 mm; 5-35 V DC | Use the drawing of the ordered hardware for mounting and cable clearance. The nominal envelope does not include plugs or antenna leads; check transmission-related power demand separately. |
| Protection | IP30; -35 to +75 deg C | Install with suitable cabinet protection and keep the operating environment non-condensing. |
Identify firmware functions that the application needs
The published list includes TCP/UDP transport, MQTT, HTTP, Modbus RTU/TCP and VPN functions. JSON is a data format, not an additional physical interface. Obtain the supported mode, payload design and firmware revision for the required service.
When replacing a serial DTU, test connection ownership, serial settings and recovery with the existing software. When providing remote maintenance, have the network owner approve authentication and access restrictions. A compatible radio module does not remove those integration tasks.
The two Ethernet ports are Gigabit interfaces, but radio throughput and latency depend on the selected module, operator service and installation. Do not convert the LAN-port rating into an advertised end-to-end performance figure.
Check power and recovery before field deployment
Record the approved configuration and a recovery method before changing remote network settings. Verify the supply at the installed router under representative cabinet loads. Route antenna and signal cables so they remain serviceable and are not damaged by doors or moving equipment.
Simulate the interruptions required by the application during a controlled test. Observe cellular registration, usable network access and the first valid application response separately. If an alternate SIM is supplied, include switching and return-to-primary behaviour in the test record.
For recurring disconnects, preserve uptime and event logs before restarting the unit. The disconnection troubleshooting guide distinguishes power, network and application failures.
Questions when selecting the radio version
Q1. Are full 5G and RedCap interchangeable configurations?
No. Confirm the exact module, supported network modes and bands, and whether its service capacity meets the application. Do not use a quotation for one variant as evidence of the performance or network compatibility of another.
Q2. Will the router improve poor coverage inside a metal cabinet?
The module cannot remove the installation's radio obstruction. Assess an appropriate external antenna position, cable losses and the intended operator's service. Verify application performance after installation rather than relying only on a coverage map.
Q3. When is a 4G model sufficient?
Where the measured workload, service availability and expected product life can be met by the offered 4G configuration. Compare TR321 when its ports and radio service meet the requirement; select TR323 for a justified configuration need, not its name alone.
Information for a radio and interface quotation
Send METRAVON the TR323 application requirements, country, operator, traffic profile and local network sketch. Identify RS485 duties, any dual-SIM requirement and the acceptable recovery sequence. These details allow the offer to distinguish the router, module, antennas and integration work.
