The transmitter Erone type S3TR128E2 is a very high security transmitter with GFSK modulation. The high degree of security is ensured by a 128-bit serial number, with a AES128 encryption and by a proprietary “rolling code algorithm” that avoids the risk of the scan and the subsequent retransmission of the code copied. A special system keeps aligned transmitter and receiver. An innovative feature allows to set up the autostore capability of a new transmitter using a remote control already in memory, which enables it by proximity. This avoids to access the receiver for memorizing a new remote control.
