Description

The VT-DTMSA5-433 module is designed as a wireless sub module for wireless communication between devices like controls, POS systems, data collectors etc. It offers several addressing modes and relieves the host systems of wireless-specific task such as checksum calculation, address resolution.

It can be deployed whenever the wireless exchange of data packet between two or more parties is required.

Thanks to its small size and the external SMA antenna connector, the module can easily be installed in existing systems without any external circuits.
