1) Stability optimized (stronger) FEC
2) RF Output power -30 to -15 dBm for all models with variant “R” (e.g. RAy3-24R or RAy3-24NR)
3) Model RAy3-24S (produced December 2018 till April 2019) has MTU 2048 bytes. All other models have MTU 10240 bytes.
4) Encryption is possible only with model variants ‘X, ‘S’ and ‘E’. Variants ‘S’ and ‘X’ means the unit is equipped with HW encryption support. Variants ‘E’, ‘S’ and ‘X’ allow SW encryption, while encryption is prohibited in Variant ‘N’.
