XDM2510H - 05/28/10
1.0 XDM2510H Introduction
RFM’s XDM2510H is a 2.4 GHz IEEE 802.15.4 WirelessHART compliant radio module designed to provide excel-
lent communications reliability and long battery life in a wide range of industrial automation applications. The
XDM2510H employs DUST Networks’ SmartMesh IA-510™ technology which blends the reliability of self-
organizing and self-healing mesh networking with synchronized power duty cycling to achieve very long battery
life operation. The XDM2510H is certified for unlicensed operation in the USA, Canada and Europe. An example
XDM2510H network is shown in Figure 1. The network consists of an XG2510HE network manager and
XDM2510H-based sensor nodes. The XG2510HE provides both the XDM2510H network management function
and the application interfaces. The XG2510HE includes an Ethernet port that supports XML-based network com-
mands, and two RS232 serial ports that support binary string network commands, diagnostics, etc.

Figure 1
SmartMesh IA-510™ traffic is organized in to TDMA frames consisting of 31.25 ms time slots. The XG2510HE
assigns time slots to each XDM2510H node in the network, and then maintains a precise report interval (frame-to-
frame period) to provide a highly synchronized network. Network operation also hops from channel to channel in a
pseudorandom pattern to mitigate the effects of multipath fading and narrowband interference. The XDM2510H
monitors performance on each channel and will temporarily discontinue the use of a channel that is showing poor
performance statistics.
Mesh networking allows traffic to be passed from XDM2510H node to node so that messages can be delivered to
and from nodes that can not communicate directly with the XG2510HE network manager. At least two paths are
maintained by the network for communication between each node and the network manager. As needed, a new
paths will be automatically established to replace a failing paths to maintain network performance.

As shown in Figure 2, each sensor node in the network consists of an XDM2510H radio module and a host mi-
crocontroller with sensor I/O electronics. The host microcontroller communicates with the XDM2510H radio mod-
ule on a serial interface using binary command and response strings.
