Features
Product Introduction
TD-DTU-PRO is a data acquisition and remote transmission device, which has an embedded high capacity battery, which eliminates the need to have external power supply, a multi-frequency band of 2G +4G and the GNSS positioning capabilities, allowing remote data acquisition and transmission in different countries and regions around the world where power supply is not accessible on-site.
The wireless communication device is designed along the lines of the Mini-PCIE standard interface, and it can support various modules with different frequency ranges, connecting to the wireless network of a specific country and region around the world.
Strong Compatibility
Facilitates a variety of photoelectric ports and gatekeeping to a variety of communication interfaces of on-site meters.
Available Range
Allows a variety of protocol settings to be used in plug and play mode (no development). It also allows the growth of on-site applications such as the remote control and the collection of environmental data.
Multi-Mode All Network Connectivity
Since various countries have dissimilar communication cards, 2G/3G/4G and various data packets can be selected at the will of the user. The communication cards of Tespro can be used worldwide.
Intelligent Automatic Meter Reading Helper
Install and leave it to do the rest. It will automatically and ideally complete the meter - reading work. The smart variant of TA - DTU LTE Pro has the potential to save a considerable amount of the communication costs.
