Encryption Key Management
The DCR822 has four options for encryption keys:
• Standard: This is the most basic level of security. Each encryption key is unique to the DCR822 and there are
only 256 key instances available to be transferred to a transmitter. The receiver tracks the number of keys gener-
ated and the number of times each key is transferred. Once a Standard key has been transferred 256 times, you
will be alerted that a new key must be created.
• Shared: Once generated by the DCR822 and transferred to a transmitter, the encryption key is available to be
shared (synced) by the transmitter with other transmitters/receivers via the IR port.
•
Universal:
This is the most convenient encryption option available. All encryption-capable Lectrosonics trans-
mitters and receivers contain the Universal Key. The key does not have to be generated by the DCR822. Simply
set a Lectrosonics encryption-capable transmitter and the DCR822 to Universal, and the encryption is in place.
This allows for convenient encryption amongst multiple transmitters and receivers, but not as secure as creating a
unique key.
• Volatile: This is the most robust encryption option available. If the transmitter is powered off, it must be re-
sync’d. If the receiver is powered off, a new key must be generated and sent to the transmitter. In encryption
terms, this is the “one time use” key management policy.
Encryption Keys
The DCR822 generates high entropy encryption keys to sync with encryption-capable transmitters. The user must
select a key type and create a key in the DCR822, and then sync the key with the transmitter.
1. Begin by selecting
a key type
.
IR&Keys --> Key Type --> Standard, Shared, Universal, Volatile.
2. Next, select MAKE KEY to generate a new key. Select “Yes” to confirm Make Key.
IR&Keys --> Make Key
NOTE: When Universal Key type is selected, there is no prompt to create key.
3. A message will pop up on the screen stating that an Encryption Key has been created.
4. Sync new key with transmitter (see
Send Key
). The transmitted audio will then be encrypted with the new key.
Send Key
Send or retrieve (get) encryption keys. Select SEND KEY to send key with key type to any compatible transmitter.
Success will be indicated by
IR SYNC SUCCESSFUL
. Failure will be indicated by
IR SYNC FAIL
.
Sync Settings
Allows sending or retrieving setup data, including frequency, name and talkback settings, via the IR port. There are
two ways to initiate a sync.
Sync options: Choose to send frequency, send all settings, retrieve (get) frequency or retrieve (get) all settings from
a transmitter. Use the
UP
and
DOWN
arrows to select a function and
MENU/SEL
to initiate sync.
NOTE: You must position the transmitter’s IR port directly in front of the DCR822 IR port, as closely as possible, to
guarantee a successful sync.
