Like name implies is simply that, a modem to supply internet connection to already existing devices. Imagine USB stick modem just for industrial purposes with rugged housing that can be controlled through AT commands and provides wide range of connectivity options like 2G (EGPRS) to 4G LTE Cat 1, LTE Cat-M1 and NB-IoT.

Bandwidth

TRM240 features by CAT 1 4G modem so its speeds are up to 10 Mbps for download and 5 Mbps for upload.

TRM250 features by CAT M1/NB 4G modem that has speeds capped at 1 Mbps.

Notes:

-Modems (TRM240 and TRM250) do not support RMS.

-TRM240 and TRM250 use one external antenna connected through SMA (003R-00225) for LTE.

-About internet connectivity, you only need to connect modem to desired device with USB cable and install drivers, no further actions are needed.

• TRB Gateways

“A gateway is a device that combines some functions of a modem and a router.”

Much more functional than TRM modems, on top of simply providing internet connection, they can be controlled through RMS (Remote Management System) Depending on model they feature serial ports (RS485 and RS232) to connect to industrial devices, Inputs/Outputs, to connect sensors and device control, or RJ45 Ethernet port. They have GUI to connect, control and configure through browser and can establish VPN services for secure remote connection, Modbus, MQTT and other protocol for device control and data transfer.

Notes:

-How to implement Dhcp functionality and connect the final device to the internet on TRB gateways.

Only TRB140 has RJ45 Ethernet port, other models use USB cable (like Modem) and virtual network interface. When USB cable is Connected to a PC, it functions exactly like normal network interface.

For other models than TRB 140, their purpose is to use inputs/outputs from the RS485 or RS232 ports to connect to specific devices and send data from them via the Internet, the USB port is mainly there for configuration.

-How to use USB port without drivers for Gateways devices.

Since TRB Gateways have an operating system and use a virtual network interface to connect to devices via USB, all that is required is for the device to have the necessary generic USB drivers for the USB port to work.

FAQ

Q: What is the meaning Virtual Network Interface for Gateways?

A: It means that Gateways do not have physical Network Interface Card (NIC), it uses modem processor to create virtual interface imitating it's functions.

The virtual network interface is used to create a connection like an Ethernet cable.

• RUT Routers

They have widest variety. Depending on model one device can support wider variety and bigger number of devices connected, while featuring all previously mentioned capabilities and more, like GPS, multiple ways to connect to the internet (Wired WAN Mobile Connection WiFi Station mode), double sim cards for connection redundancy, they are simply much more universal than Modems and even Gateways.

“ A RUT allow multiple devices like phones, tablets and computers to use a single network through a wired or wireless connection.”

Comparison between RUT and RUTX

*RUTX11 uses CAT 6 LTE (up to 300Mbps/50Mbps) Connection versus RUT955 CAT 4 LTE (150Mbps/50Mpbs).
