Mounting
Physical dimensions and how to mount the RS-485 Node on site.
Dimensions not in the official catalogue — confirm before publishing
The official 2026 VIoT Catalogue doesn't list physical dimensions or weight for the RS-485 Node. The figures below come from earlier product documentation and should be confirmed against current production units before being published as fact.
| Dimensions (L x W x H) | 85mm x 65mm x 30mm (unconfirmed — see note above) |
| Weight | ~150g (unconfirmed — see note above) |
| Enclosure | Industrial-grade plastic housing, external SMA antenna connector |
The RS-485 Node's compact enclosure is designed to sit close to the Modbus RTU devices it's polling — typically inside or right next to the same panel or junction box the instruments are already wired into, since it needs a direct RS485 bus connection to them. The enclosure's small footprint makes it easy to fit into an existing panel without needing significant extra space.
Mounting Options
- Panel/enclosure mount — fixed inside an existing control panel or junction box alongside the Modbus devices it connects to
- Wall mount — fixed directly to a wall near the connected instruments, using the enclosure's mounting points
- DIN rail mount — if a DIN rail adapter is available for this enclosure, this is a common option for panel installations (confirm availability before specifying)
Placement Guidelines
- Keep the RS485 wiring run between the node and its Modbus slave devices as short and direct as practical, and follow standard RS485 bus wiring practices (proper termination, twisted pair, shared ground reference)
- If the node will be mounted inside a metal control panel or cabinet, be aware that metal enclosures can significantly attenuate the LoRaWAN signal — routing the antenna outside the cabinet (via the optional external antenna and cable) is strongly recommended in this case
- Position with a reasonably clear path toward the nearest VIoT Gateway; industrial sites with lots of machinery and metal structures will see more signal attenuation than open environments
- Leave the terminal block and power input accessible for wiring and future maintenance
