M1310-1 MOTE DATASHEET DUST NETWORKS™

CONFIDENTIAL

Product Description

The SmartMesh-XD™ M1310-1 embedded wireless mote uses Time Synchronized Mesh Protocol (TSMP) to enable low-

power wireless sensors and actuators with highly reliable wireless mesh networking. The

M1310-1 is tailored for use in

battery- and line-powered wireless devices for applications that demand proven performance, scalability, and reliability.

The M1310-1 uses a 900 MHz radio to achieve more than 200-meter communication distance outdoors, while consuming

down to 9

µA in a typical network deployment. The combination of extremely high reliability and low power consumption

enables applications that require very low installation cost and low-maintenance, long-term deployments.

The standard serial interface of the M1310-1 gives it flexibility to be used in a wide variety of different applications, from

industrial process control to security, to lighting. When integrated into a product, the M1310-1 acts like a network interface

card (NIC)—it takes a data packet and makes sure that it successfully traverses the network. By isolating the wireless mesh

networking protocols from the user, the M1310-1 simplifies the development process and reduces development risk.

ADVANCED INFORMATION CONFIDENTIAL Pinout 5.0 Pinout The M1310-1 has two 11-pin Samtec MTMM-111-04-S-S-175-3 (or equivalent) connectors on the bottom side for handling all of the I/O. The third pin in each of the connectors is not populated, and serves as a key for alignment. The connectors are mounted on opposite edges of the long axis of the M1310-1. The M1310-1 provides a bidirectional flow-controlled serial interface (serial protocol is specified in 7.3.1).

ADVANCED INFORMATION CONFIDENTIAL 6.2 Mote Boot Up Inrush Current During power on, the mote can be modeled as a lumped impedance, as shown in Figure 3. With a source impedance (Rsrc) of 1 Ohm, the inrush current on the mote appears as shown in Figure 4. Figure 3 M1310 Equivalent Series RC Circuit Figure 4 Vcc Inrush Current 6.3 Serial Interface Boot Up Upon M1310-1 power up, the MT_CTS line is high (inactive).

ADVANCED INFORMATION CONFIDENTIAL Interfaces 7.0 Interfaces 7.1 Timestamps The M1310-1 has the ability to deliver network-wide synchronized timestamps. The M1310-1 sends a time packet (as described in Table 40) through its serial interface when one of the following occurs: • • Mote receives an HDLC Get Parameter request for time/state (see Table 39) Mote TIME signal is activated The TIME pin is optional and has the advantage of being more accurate.
PAGE 9
ADVANCED INFORMATION CONFIDENTIAL 7.2 Interfaces Status LED Signal The M1310-1 provides an output that can be used to drive a status LED. This signal indicates network connectivity information which is most useful during mote installation. Alternatively, the mote’s network status may be polled via serial using the Get Parameter request (see 7.3.3.6) with the mote state parameter (see 7.3.4.3). See Figure 1 for an example application circuit.

PAGE 12
ADVANCED INFORMATION CONFIDENTIAL Interfaces 7.3.1.2.3 Data Flow into the Mote Serial Port Figure 10 illustrates the process the mote uses to receive serial data: The mote may receive serial packets for local commands (not intended for wireless transmission) at any time regardless of the MT_CTS status. The mote signals its readiness to receive serial packets for wireless transmission (serial payload command 0x80) by driving MT_CTS active low.
PAGE 13
ADVANCED INFORMATION CONFIDENTIAL 7.3.3 Interfaces Mote Commands The mote command interface provides a way to send and receive network packets, access local configuration and diagnostics, and receive time stamps. All packets between the microcontroller and the mote are encapsulated in the HDLC format (RFC 1662) and have the following structure.
PAGE 14
ADVANCED INFORMATION CONFIDENTIAL Interfaces 7.3.3.1 Command 0x80 Serial Payload Sent to Mote Serial Serial Data Packets going into the mote serial port use the command type 0x80. Upon reception of the packet, the mote forwards it to the network. The format of the serial packet payload is transparent to the mote. The maximum length of the payload is 80 bytes (excluding byte-stuffing bytes). There is no response by the mote upon reception of this command.
PAGE 15
ADVANCED INFORMATION CONFIDENTIAL 7.3.3.4 Interfaces Command 0x84 Time/State Packet Time data packets use the command type 0x84. The time packet includes the network time and the current real time relative to the Manager. The mote sends this response when it receives a Get Parameter request with time as the parameter (described later) or when the TIME pin is strobed high to low for minimum of min_strobe_length, as defined in Table 12. Usage of the TIME pin is described in section 7.1.
PAGE 16
ADVANCED INFORMATION CONFIDENTIAL Interfaces 7.3.3.6 Commands 0x89 and 0x8A Get Parameter Request/Response The Get Parameter command allows a number of configuration parameters in the mote to be read by serial. When a Get Parameter Request command is sent, the response to the request is sent within the diag_ack_timeout (see Table 12). The command structure for individual parameter types can be found in section 7.3.4.
PAGE 17
ADVANCED INFORMATION CONFIDENTIAL 7.3.3.8 Interfaces Command 0x8D Reset Mote Upon receiving this command, the mote notifies its children about an upcoming reset, then proceeds to reset itself. The delay to the actual reset depends on the network configuration. Table 24 Command 0x8D Reset Mote Msg Byte Description 1 Data Type Cmd Type 7.3.4 Value unsigned char 0x8D Mote Get/Set Command Parameters This section specifies the parameters that may be used with the Set and Get Commands.
PAGE 18
ADVANCED INFORMATION CONFIDENTIAL Interfaces 7.3.4.2 Parameter Type 0x01 Network ID The network ID is the identification number used to distinguish different wireless networks. In order to join a specific network, the mote must have the same network ID as the network Manager. This parameter is only valid for the Set Parameter command. Upon receiving this request, the mote stores the new network ID in its persistent storage area, but continues to use the existing network ID.
