The MSI-P700
is a low cost, high performance wireless card providing the IEEE
802.15.4
protocol using a XBee PRO module operating at an rf frequency of 2.4
GHz. The module is configured to support NonBeacon communications
that operate in a Peer-to-Peer network topology not dependent upon the
Master/Slave relationships. Modules remain synchronized without use of
master/server configurations for rapid synchronization times and fast
cold start times. It can also be programmed for NonBeacon mode as
either a Coordinator or End Device. The Coordinator mode can be
configured to use either direct or indirect transmissions. It will also
support Unicast or Broadcast communications.
A 16C550 UART interfaces the XBee module to the PC/104 bus. The UART
provides a 16 byte transmit and receive FIFO and baud rates are
programmable from 1200 to 115,200 bits/s. Automatic hardware RTS and
CTS flow control is used to prevent overflow of the local receiver and
remote receiver FIFOs. The card I/O address is jumper selectable for
COM1 thru COM4 with an optional 16-bit offset address. Interrupts are
jumper selectable for IRQ3 thru IRQ5 and IRQ9 thru IRQ15. The
I/O provides 6 lines individually selectable as either an analog
input
(0-5V range, 10-bit resolution) or a TTL input or output, and 1 TTL
input. Two analog outputs (0-5V range, 10-bit resolution) are
also provided. Unused UART control lines provide 3 input and 2 output
TTL lines. All
I/O lines have varistor surge suppressors for transient voltage
(lightning, etc.)
protection.
The
antenna connection to the card is provided by a SMA bulkhead connector.
A 6" cable attaches this connector to the rf module which permits its
removal from the card
bracket for mounting into the user enclosure as an option. A sample
BASIC test program is
supplied that illustrates programming of the card for various XBee PRO
commands. A BASIC interpreter for running this program is available at
no charge.
