Secure Communications
The receiver and transmitter are capable of decoding and encoding secure communications if a
DES-OFB / AES Encryption Module is installed. To successfully decode or encode a transmission,
the encryption module must be programmed with a valid encryption key using the Motorola KVL 3000
Plus Keyloader in conjunction with a Daniels Keyloader Cable. The Daniels Keyloader Cable plugs
into the front panel RJ45 jack on the front of the receiver or transmitter module.
Consult Keyloader instructions for details on loading a key. A loaded key may be zeroized by pulling
the CLEAR KEYS 1, then the CLEAR KEYS 2 inputs to ground 500 ms apart. Alternately, the
CI-BC-4E Base Controller or Universal Interface Card (UIC) may be used to clear the keys for all
modules in a system with a single key press of the switch marked ZEROIZE KEY. The CI-BC-4E
Base Controller can also be used to control whether the transmitter outputs a secure or a clear signal.
Firmware upgrades
Receiver and transmitter firmware upgrading is performed with the PC-based firmware flashing
software. A USB Type A to 5-pin Mini-B cable is used to connect the USB port of an IBM-compatible
computer to the USB port on the front panel of the receiver or transmitter module.
Firmware upgrades can be found on the Daniels Electronics Ltd. website at www.danelec.com.
