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 from power source.
2 Hold down RESET button on the power injector/supply 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
(45 to 60 seconds).
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
• VLAN disabled
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 a GPS source. A Global Positioning System (GPS) kit
from Exalt is required to implement external source synchronization. Contact your Exalt representative
for details.
Synchronization implementation requires one synchronization source for each link.
Virtually any combination of hubs and repeater sites, star configurations, and/or backbones can be
implemented with synchronization. It is typically necessary or ideal in each configuration to match the
following parameters on every radio in the network:
• Link Distance – Match to the longest distance link in the network.
• Frame Length – Match to the lowest frame length to optimize total system latency (for example,
for TDM networks) or match to a highest frame length to optimize user throughput. Choose an
intermediate value to compromise between latency and throughput.
Note: In many cases, the system design will not be identical to the factory default
configuration, and in some cases, these differences prohibit the installation of the radio. If at
all possible, obtain a computer and configure the radio terminals using the browser-based
GUI. See Exalt Graphical User Interface (GUI)
for details.
