Radio Reset
Use the reset function if the IP address and/or passwords are lost. Use the following steps to perform a
critical parameter reset:
1
Remove power from the radio by disconnecting the AC adapter from the power injector.
2
Hold down the RESET button on the power injector while applying power.
Hold the RESET button down through the entire power cycle and monitor the DATA+POWER
left LED on the power injector. Release the RESET button only after the LED is in the steady state
(approximately 2 minutes).
3
Release the RESET button.
The following configurations are reset on the radio:
•
IP address = 10.0.0.1
•
IP mask = 255.0.0.0
•
IP gateway = 0.0.0.0
•
Administration password = password
•
User password = password
Radio Synchronization
The radio synchronization feature improves the performance of Exalt radios operating in the same
frequency band and that are collocated (such as in repeater and hub configurations). Radio
synchronization ties radio systems together to operate off of a common clock system, ensuring that all
radios simultaneously transmit and receive, and thus eliminating near-field interference issues and
related radio system coupling.
Synchronization Modes
Synchronization can be accomplished using either an
internal
or
external
source. In either case, one
radio in the network must be defined as the primary sync source (A) radio.
A Global Positioning System (GPS) kit from Exalt is required to implement external source
synchronization. GPS synchronization is not available on all radio models. Contact your Exalt
representative for details.
Synchronization implementation only requires one synchronization source for any interconnected
network. The system also implements a redundancy configuration to maintain a majority of the
synchronization functions in case of primary radio failure.
For internal synchronization, the primary radio is designated SYNC SOURCE. This radio provides the
master timing for all interconnected radios. SYNC SOURCE radios and collocated radios must be
configured as Radio A.
Collocated radios must be in SYNC RECIPIENT mode; they receive sync signaling from the SYNC
SOURCE, either directly or daisy-chained with other collocated radios. Alternatively, the radio(s) can
be placed in AUTO SYNC mode. AUTO SYNC synchronizes the radios to any source provided on the
SYNC IN port. However, if an appropriate synchronization signal is unavailable, the radio becomes
the SYNC SOURCE for all connected radios.
