Selection Guide
Choose by site condition first, not by model name.
Serial gateways look similar on the product shelf. The safer way is to confirm the network, serial interface and installation condition first, then compare models below.
Prepare these details before inquiry
- Network: Ethernet, WiFi, 4G or LoRa
- Serial side: RS485, RS232 or TTL
- Protocol: Modbus RTU, transparent transmission or custom
- Port count, baud rate, power supply and antenna position
1
Confirm the uplink network
Use Ethernet for fixed LAN cabinets, WiFi for covered workshops, 4G for remote sites, and LoRa when wiring is difficult over distance.
2
Confirm the serial devices
Check whether the device is RS485, RS232 or TTL, and confirm the baud rate, protocol and how many serial ports are needed.
3
Confirm the site limits
Power supply, antenna installation, cabinet space, metal shielding and outdoor conditions often decide whether a model works reliably.
Site condition
Typical direction
Main thing to verify
Remote cabinet or field device
Cellular serial gateway
4G band, SIM card and signal strength
Factory LAN or control room
Ethernet serial gateway
IP mode, Modbus TCP mapping and network security
WiFi-covered workshop
WiFi serial gateway
WiFi stability, coverage and power supply
Multiple serial devices
Multi-port serial gateway
Port quantity, protocol mix and polling load
Practical tip: if you are unsure, do not start by asking “which model is best”. Start with the site network and the device interface. That usually saves one round of wrong selection.
