M1310-1 MOTE DATASHEET DUST NETWORKS™ 9
CONFIDENTIAL
7.2 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.
7.3 Serial Interface
The M1310-1 offers a well-defined serial interface that is optimized for low-powered embedded applications. This serial
interface offers a serial port comprised of the data pins (TX, RX) as well as the handshake pins (
MT_RTS, MT_CTS,
SP_CTS) used for bidirectional flow control. Through this port, the M1310-1 provides a means of transmitting and receiving
serial data through the wireless network, as well as a command interface which provides synchronized time stamping, local
configuration and diagnostics.
7.3.1 Serial Handshake
The serial handshake provides for flow control of packets transmitted via the M1310-1 serial interface. Packet delineation and
error control are handled separately. The handshake supports the following:
• Full-duplex communication
• Bidirectional byte-level flow control
7.3.1.1 Serial Port
The five-pin serial port is comprised of the data pins (TX, RX) as well as the handshake pins (MT_RTS, MT_CTS, SP_CTS)
used for bidirectional flow control. This port supports 9600 bps operation in full-duplex mode. The handshake signals are
active low.
