| Listed field baud rates | 2,400–9,600 bps |
| Network protocol | 4G LTE with MQTT |
| Configuration | Windows utility over USB |
| USB configuration rate | 115,200 bps |
| Operating temperature | −25 to 85°C |
Selection and System Integration
Verify target-country LTE bands, SIM/APN requirements, device register maps and MQTT payload format before ordering. The supplied sheet does not list regional radio bands, so overseas compatibility must be confirmed for the specific modem version.
Installation and Application Notes
Agree on broker address, authentication, payload mapping, cloud ownership and any subscription terms. A gateway is not automatically compatible with every cloud platform or every RS485 device. Test the complete communications path before rollout.
Sample Evaluation
Before a larger order, check the selected sample against the agreed specification using representative operating conditions. Confirm wiring, power, output units and controller communication, then record reference measurements and any configuration changes. Agree on the required documents, packing and replacement components as part of the quotation.
Application FAQ
Will it work worldwide with any SIM?
That cannot be assumed. Confirm the regional modem bands, operator approval, SIM/APN settings and platform configuration for the destination.
