SERIAL DATA INTERFACE
The serial asynchronous interface allows connection to external serial devices. It is shared between user data
and unit’s command/status information. All commonly supported baud rates, parity and bit configurations
are available up to 115.2 kbps.
POWER INTERFACE
The power interface allows connection to an unregulated DC power source. The DC power source (third-party
or user supplied) must provide DC power of 4.2V±5% DC. The standalone unit’s RF interface is a 50-ohm im-
pedance matched standard MMCX connector as required by regulation.
POWER CONSUMPTION
troller through the data interface control lines (RTS or DTR), or by SLEEP input line (CMOS/TTL compatible
input lines).
Operating Modes
The operating modes for LMR400 can be set through the CLI, and/or through AWLaunch. The following oper-
ating modes are available for LMR400 :
• The sleep mode has automatic transmitter activation by an internal real-time clock, or by an external
controller through the data interface control lines (RTS and DTR), or by the triggering of the external Sense
Inputs.
• Adaptive RF Power control used by Remotes minimizes the transmit power levels and interference to
co-channel and adjacent channel users. It also reduces the Remote’s power consumption.
Management Tools
The built-in management tools along with AWLaunch (configuration and monitoring software application)
will provide the following benefits:
• Easy user’s interface for system configuration and monitoring using well developed CLI or intuitive GUI.
• An ability to monitor status, alarms and radio performance through the intuitive GUI.
• Software upgrades and improvements can be downloaded from AWLaunch to the units connected with
PC/PDA.
Security
The system provides wireless media access protection as well as data encryption. The following are its key
features and benefits:
• The Key Sequence generated by Pseudo-random generator scrambles the fully formatted frame (includ-
ing Frame’s CRC). This provides the wireless media access protection.
• User selectable Frequency Hopping Pattern provides another level of the wireless media access protec-
tion.
At the same time it allows operators to increase the number of links deployed in the same location.
