5.0 Available operation modes in WINC 900A and Applicable applications
Resulting from our long term commitments to our products and tight relationship with our customers,
WINC 900A can be configured to various operation modes as followings:
1.
Point-to-Point Dial-up connection mode
2.
Point-to-Point Auto connection mode
3.
Multiple-to-One Wireless Dynamic Data Reporting and Monitoring (WDDR) mode
4.
Multiple-to-Multiple Transparent mode
The first two operation modes, the Point-to-Point Dial-up connection mode and the Point-to-Point
Auto connection mode, were developed on the foundation of the traditional point-to-point
asynchronous mechanism that comes with build-in protocol providing error free data transmission.
In the 3rd operation mode, the Multiple-to-One Wireless Dynamic Data Reporting and Monitoring
operation mode, the build-in broadcasting function transmits the in-coming data from the connected
external device to the air. All remote units operate/broadcast without build-in protocols for packet
collision prevention and packet re-transmission; therefore, the transmitted packets from remote units
might not be received by the information collection unit.
In the Multiple-to-Multiple transparent mode, each WINC 900A operates as a dumb transceiver fully
controlled by industry oriented management systems in transmitting and receiving packet to/from the
air. The correctness of the data is totally relay on the upper level management system. There is
no involvement of build-in protocols from WINC 900A.

Summary of various operation modes, applicable applications, and FAQ
5.1.1.1 Point-to-Point Dial-up connection operation mode
The spirit of WINC 900A asynchronous modem development is to deliver a wireless
asynchronous modem using traditional dial-up connection mechanism with error free protocol.
The dial-up connection process has been detailed in section 4.3.1. After the establishment of
the point-to-point linkage connection, the user can perform the functionality provided by the
communication software just like the connection established between two PC modems via
telephone line.
5.1.1.2 Applicable applications
•
The traditional remote dial-up connection
•
The one-to-multiple polling connection for data distribution or data collection process.

Traditional Dial-up Connection
The user issues the ATDT command
or activate the connection function
from the communication software to
the remote unit and establish the point-
to-point connection.
One-to-multiple Polling Connection
The user adopts the polling mechnism
in their application program and
initiates the dial-up function to
establish wireless connection with each
remote units by turns.
