7.1.2.3. Encryption
Encryption
List box {Off; AES-256-CCM}, default = "Off"
AES 256-CCM (Advanced Encryption Standard) can be used to protect your data from
an intrusion on Radio channel. When AES 256 is On, control block of 16 Bytes length
is attached to each frame on Radio channel. AES requires an encryption key. The
length of key is 256 bits (32 Bytes, 64 hexa chars). The same key must be stored in
all units within the network.
Mode
List box {Passphrase; Key}, default = "Passphrase"
This parameter occurs only, if parameter "
Encryption
" is set to "AES-256-CCM".
Passphrase
The key can be automatically generated based on a Passphrase. Fill in your
Passphrase (any printable ASCII character, min. 1 char, max. 128 char). The same
Passphrase must be set in all units within the network. This parameter occurs only,
if parameter "
Mode
" is set to "Passphrase".
Key [64 hex digits]
The key can be configured manually (fill in 32 Bytes of 64 hexa chars). The same
key must be in all units within the network. This parameter occurs only, if parameter
"
Mode
" is set to "Key".
7.1.2.4. Transparent protocol (Bridge mode)
Bridge mode with fully transparent Radio protocol is suitable for all polling (request-response) applications
with star network topologies, however repeater(s) are possible.
A packet received through any interface (bridged with the radio interface) is broadcasted to the appro-
priate interfaces of all units within the network.
Any unit can be configured as a repeater. A repeater relays all packets it receives through the radio
channel. The network implements safety mechanisms which prevent cyclic loops in the radio channel
(e.g. when a repeater receives a packet from another repeater) or duplicate packets delivered to the
user interface (e.g. when RipEX2 receives a packet directly and then from a repeater).
Transparent protocol does not solve collisions on the radio channel protocol. There is a CRC check of
data integrity, however, i.e. once a message is delivered, it is 100% error free.
