The remote device monitoring system

5.1.4.1   Multiple-to-Multiple

Transparent operation mode

For some one-to-multiple, multiple-to-one or multiple-to-multiple applications, a fully
controlled transmitting and receiving two way capability is required.      To meet this
requirement,  our WINC 900A can be configured as dumb transceiver fully controlled by higher
level application system.

The configuration steps and related AT command sets for  setting are briefed in the following :

AT&!E

to switch into transparent mode from point-to-point operation mode.

AT&!Q

to return to point-to-point operation mode from transparent mode.

AT\Cn

to specify the operation channel from 0 to 7.
this operation channel must be specified before changing WINC 900A
operation mode from the point-to-point to transparent.  Otherwise, units
can not receive packets.

Please note, the transparent mode can not be terminated by restoring manufacture
default or hardware reset process.    User must issue “AT&!Q” to exit the transparent
mode.

WINC 900A

Mobile location and Fleet management system
WINC 900A can be configured into broadcast
mode transmitting bus location or other
information from each buses to the air and the
designated monitoring unit will receive the
transmitted packet in the air.    The monitor unit
will do its best to receive packets, but some
packets might not be collected accordingly.

Remote sensor  reporting system
For some of those non-timing sensitive operations,
the build-in broadcast mode above is also
applicable for data acquisition or monitoring
applications.
