Chapter 1 Product Introduction
1.1 Overview
Ursalink UR75 is an industrial cellular router with embedded intelligent software features that are
designed for multifarious M2M/IoT applications. Supporting global WCDMA and 4G LTE, UR75 provides
drop-in connectivity for operators and makes a giant leap in maximizing uptime.
Adopting high-performance and low-power consumption industrial platform of 64-bit CPU and wireless
module, the UR75 is capable of providing wire-speed network with a typical 2.9 W power consumption
and ultra-small package to ensure the extremely safe and reliable connection to the wireless network.
Meanwhile, the UR75 also supports Gigabit Ethernet ports, serial port (RS232/RS485) and I/O
(input/output), which enablesyou to scale up M2M application combining data and video in limited time
and budget.
The UR75 is particularly ideal for smart grid, digital media installations, industrial automation, telemetry
equipment, medical device, digital factory, finance, payment device, environment protection, water
conservancy and so on.

data receiving and transmission. “AUX” interface is for enhancing signal strength, which cannot be used
separately.
2.10 Mounting the Router
The router can be placed on a desktop or mounted to a wall or a DIN rail.
2.10.1 Wall Mounting (Measured in mm)
Use 2 pcs of M3×6 flat head Phillips screws to fix the wall mounting kit to the router, and then use 2 pcs of
M3 drywall screws to mount the router associated with the wall mounting kit on the wall.
Recommended torque for mounting is 1.0 N. m, and the maximum allowed is 1.2 N.m.
2.10.2 DIN Rail Mounting (Measured in mm)
Use 2 pcs of M3×6 flat head Phillips screws to fix the DIN rail to the router, and then hang the DIN rail on
the mounting bracket. It is necessary to choose a standard bracket.
