Real-time Clock
The LTP5903-WHR has a battery-backed real-time clock (RTC) with a typical lifetime of 5-7 years (lifetime up to 15 years if
the manager is normally powered), assuming the manager is operating at 60 °C average ambient temperature and at 10% duty
cycle. Upon bootup, the RTC initializes the software system clock that handles timekeeping while the system is operating.
The software system clock is the reference for UTC time values readable through the software APIs, command line interface
(CLI) and Admin Toolset Web interface, as well as the UTC time values visible in manager log files. The system clock may
be set manually using the Admin Toolset Web interface, or through the Linux command shell. The accuracy of the software
system clock is typically 1 min/month at 25°C, though may vary as much as 10 min/month at temperature extremes. To
support applications less tolerant of such drift, the LTP5903-WHR software includes an NTP client to periodically
synchronize software system time to an outside source. The NTP client is configurable using the Admin Toolset Web
interface, or through the Linux command shell.

SmartMesh WirelessHART Intelligent Networking
Platform
The SmartMesh WirelessHART LTP5903-WHR embedded network manager is built upon Dust Networks’ Intelligent
Networking Platform, which provides dynamic network optimization, deterministic power management, intelligent routing,
and bandwidth flexibility to achieve the carrier class data reliability, and ultra-low power and ease of use required for
industrial automation applications.
6.1
Dynamic Network Optimization
Dynamic network optimization allows the LTP5903-WHR to address the changing RF requirements in harsh industrial
environments resulting in a network that is continuously self-monitoring and self-adjusting. The LTP5903-WHR manager
performs dynamic network optimization based upon periodic reports on network health and link quality that it receives from
the network motes. The manager uses this information to provide performance statistics to the application layer and
proactively solve problems in the network. Dynamic network optimization not only maintains network health, but also allows
the LTP5903-WHR to deliver deterministic power management.
6.2
Deterministic Power Management
Deterministic power management balances traffic in the network by diverting traffic around heavily loaded motes (for
example, motes with high reporting rates). In doing so, it reduces power consumption for these motes and balances power
consumption across the network. Deterministic power management provides predictable maintenance schedules to prevent
down time and lower the cost of network ownership. When combined with field devices using Dust Network’s industry-
leading low power radio technology, deterministic power management enables over a decade of battery life for network
motes.
6.3
Intelligent Routing
Intelligent routing provides each packet with an optimal path through the network. The shortest distance between two points
is a straight line, but in RF the quickest path is not always the one with the fewest hops. Intelligent routing finds optimal
paths by considering the link quality (one path may lose more packets than another) and the retry schedule, in addition to the
number of hops. The result is reduced network power consumption, elimination of in-network collisions, and unmatched
network scalability and reliability.
6.4
Bandwidth Flexibility
Efficient use of network resources enables Dust Networks to deliver bandwidth flexibility—the ability to assign different
levels of bandwidth to satisfy unique throughput and latency requirements. Bandwidth flexibly addresses the range of latency
and throughput needs of industrial automation applications such as request/response, fast file transfer, and alerting.

7.1.1
10/100Base-T Ethernet Interface
Ideal for remote or high-bandwidth access, the Ethernet interface provides full configuration management and data access to
the LTP5903-WHR. The port connects to an IEEE 802.3 standard 10/100Base-T PHY, accessible through the board-to-board
J10 connector. An appropriate Ethernet design requires magnetics and an RJ-45 connector.
RX_P and RX_N are the receive-side differential pair (see section 8.2 for pinout). The Rx and Tx levels conform to
10/100Base-T Ethernet.
7.1.2
Serial 1 Interface
The Serial 1 interface is designed for embedded integration with controllers. This serial interface provides programmatic
access for configuration, management, and data access to the LTP5903-WHR. The port is a 5-pin LVTTL (3.3 V) serial
interface accessible through the board-to-board J10 connector.

Restore Signal
The LTP5903-WHR supports the ability to restore its configuration settings to the Dust factory defaults. This feature is most
useful in non-embedded applications where the LTP5903-WHR configuration may be different per installation (for example,
a manager’s IP setting is forgotten and therefore unreachable). Note that while the restore feature may be used to recover a
previously “unreachable” manager, all customizations to the manager will be lost, including configuration, logs, OTAP
directory files, and persistent mote information.
