ENGINEERING
Gateway selection starts with field interfaces, protocol requirements and the upstream connection — assessed per target device, not assumed portfolio-wide.
SIGNAL PATH
KEY FIELD INTERFACES
Interface availability differs by gateway model. Confirm the required interface against the target device.
PROTOCOL SUPPORT
Never assume a protocol is available on all gateway models. Confirm against official documentation for the target device.
TYPICAL APPLICATIONS
Gateway selection depends on the application, field interfaces, upstream connectivity and environment.
ENGINEERING DISTINCTION
Industrial routers prioritise IP routing, WAN connectivity (Ethernet/cellular) and network resilience between sites and devices.
Industrial gateways prioritise field interfaces, protocol handling and data-path integration between legacy equipment and IP/cellular networks.
Some devices combine routing and gateway functions. Selection depends on required interfaces, protocols, port count and topology — not the product label alone.
CONNECTION LAYER
Serial shielding, Ethernet drops, fibre backhaul and power affect gateway projects as much as protocol configuration.
Direct answers on selection and scope — without marketing promises.
When field devices only expose serial buses or legacy protocols on RS485/RS232. A gateway translates between those interfaces and IP/cellular uplinks — if devices are already Ethernet-native, a switch or router may suffice.
Selected Teltonika gateway families document Modbus and MQTT capabilities — confirm per model and firmware. GermanSTS assesses suitability per project; it is not a guaranteed portfolio-wide feature.
Yes — serial, control and Ethernet cabling can be reviewed alongside gateway interface requirements within the same project enquiry.
Gateway capabilities refer to documented Teltonika Networks devices. GermanSTS does not manufacture gateways or RutOS.
