GENERAL DESCRIPTION
The CSM2400 module from Hetronic is a Frequency Hopping Spread Spectrum transmitter. It transmits
data in the 2.4GHz spectrum in a transparent manner. To ensure a reliable connection, the radio link is fully
redundant, with two distinct radios. Once the modules are paired, they will send data through a pseudo
random channel sequence utilizing packet-based encryption.
