Modem Comparison

MT-MVPLC1-R Modem provides communication channel with excellent noise immunity, very long reach without repeaters and protocol flexibility thanks to transparent data transfer. There are also possibilities including routing, addressing, repeating etc.

MT-MVPLC1-S Modem allows to maximize utilization of the transmission channel potential. PLC communication parameters and packet routing is constantly adapted to the conditions presented on the HV line (attenuation, noise, topology change) to achieve best ratio between speed and robustness of transmission.
