8.3 /LED
The XDM2510H provides an output to drive a status LED. This signal indicates network connectivity information,
which is useful during XDM2510H system installation. Alternatively, the XDM2510H status may be polled using
the serial Get Parameter request with the module state parameter.
8.4 Settable I/O Modes
The XDM2510H offers a choice of two I/O modes. The functionality of the interface will be determined by the set-
ting MODE input.
Both modes provide a means of transmitting and receiving serial data through the wireless network, and a com-
mand interface that provides synchronized time stamping, local configuration and diagnostics. Mode 1 imple-
ments an 8-bit, no parity, 9600 baud, three, four or five-signal serial interface with bidirectional packet-level flow
control operating at 9600 b/s. In certain designs, one or two of the serial handshake signals may be optional for
reduced pin count. Please refer to detailed descriptions of signals. Mode 3 implements an 8-bit, no parity, 9,600
baud, five-signal serial interface with bidirectional packet-level flow control and byte-level flow control in the
XDM2510H-to-microcontroller direction only.
8.4.1 Mode 1 - Three/Four/Five Signal Serial Interface (9600 b/s)
XDM2510H Mode 1 provides a three, four, or five-signal serial interface optimized for low-powered embedded
applications, and in certain designs may provide a lower pin count serial solution. The Mode 1 serial interface is
comprised of the data pins UART_TX and UART_RX, with handshake pins /MT_RTS, /MT_CTS, /SP_CTS used
for bidirectional flow control. The /MT_RTS signal is ideal for designs where the host microcontroller requires ex-
tra time to prepare to receive a packet. For example, when the host microcontroller sleeps periodically and re-
quires a wake-up signal prior to receiving a packet. Refer to Table15 for information on each pin, including details
on which pins are optional.
