Radio Communications
For units equipped with the integral radio receiver, the RF frequency configuration
parameter sets the frequency of the radio channel. Changing this parameter from its
factory setting may require re-alignment of the radio for maximum performance. The
value entered must fall within the range specified for the receiver band equipped.
Activation Formats
For Two-Tone activated units, the Two-Tone Timing parameters configures the time
duration of the activation tone codes. The three parameters, A-Time, B-Time, and
S-Time; sets the time duration for the A-Tone, B-Tone, and Single-Tone respectively.
NOTE
: The Two-Tone timing parameters are minimum values only. The actual tone
times may be longer than the specified times.
EAS Location Codes
Up to three location codes may be assigned for EAS activation. For activation to occur,
the location code of the received EAS message must match one of the three assigned
codes.
You cannot program units for both Tone and EAS activation at the same time. Therefore,
when using EAS decoding, set the A-Time, B-Time, and S-Time parameters to zero. The
UVIC is capable of being programmed for EAS, DTMF and Federal Digital decoding at
the same time. Refer to www.fcc.gov for further information about EAS messages.
128/256-bit Encryption Key
The 128/256-bit data encryption provides security against malicious operation or
monitoring. The security key is programmed during the flashing of the microprocessor
and must match the encoder ( or Commander) being used to activate the unit. A
key value of zero disables encryption and must be used if the encoder does not support
encryption. All sites in the system must use the same encryption key.
Security Key
The Security Key is a unique number assigned to the system that prevents nearby systems
operating on the same RF frequency from interfering. Like the encryption key, the
Security Key is programmed during the flashing of the microprocessor and must match
the encoder. The exception is a key value of 65535 (the default), defined as an open
system and communicates with all encoders regardless of the encoder’s key setting.
