End-User Application Software
To develop your own embedded application refer to the Software Integrator’s Guide
listed in "Related Publications."
Serial Interface
External host devices communicate with the data transceiver across the serial
interface via the asynchronous Communication Linking Protocol (CLP
TM
) com-
mands.
The data transceiver supports a default serial baud of 9600 bps, no parity, eight
data bits, one start bit, and one stop bit. The host product must provide a full duplex
(both directions at the same time) pass-through link at this speed.
Communication Linking Protocol (CLP)
The CLP application contains a set of commands that enable the host to send and
retrieve messages, retrieve and modify select configuration information, and re-
trieve status information from the data transceiver. When longer transmissions are
required to transfer data, the XMODEM file-transfer protocol provides error check-
ing during transmission across the serial link.
The CLP application provides general wireless messaging services that are inde-
pendent of the underlying RF protocol.
For a detailed description of services provided, see the Communication Linking
Protocol Reference Manual listed in "Related Publications.".
