4. Notes on Software Programming and System Operation
4.1. SET UP AND SYSTEM OPERATION
4.1.1. Setting Up MPR-2010AN or BN
Refer to the Set Up Procedure for MPR-2010AN/BN document.
4.1.2. Running a Custom Software Application or the AWID Demo Program
If AWID Demo Program is not used, it is expected user will launch a Custom Software
Application developed using the MPR_2010AN/BN TCP/IP Interface to send commands
as specified to the reader.
4.1.3. Operating Modes
Typical operating modes for MPR-2010 can be grouped into the following modes:
Search Mode – This mode is used when operator or user is not certain which family of tags is
placed on the items to be tracked. Since most tags are deterministic in nature, the reader must
cycle through each and every protocol, issue a protocol specific inquiry, to hail and to wait for a
response from tags of that specific protocol. Therefore, if there are many different protocols, for
an untrained observer, the reader response will become sluggish.
Mixed Mode:
This mode assumes the user is aware of the types of protocol in use, and furthermore, the
user made a determined effort to operate the reader in a mixed protocol mode. In this
mode, the user can decide how many and which specific protocols to be selected. Once
Mix Protocol Mode is selected, the reader will routinely cycle through each protocol, dwell
long enough for the reader to wait for a response and then move onto the next protocol. It
should be noted that in a mixed protocol mode, the tag must have sufficient time to
respond to the reader, and therefore, it can only be used on a conveyor belt arrangement,
with specific speed restrictions.
Single Protocol Mode
Single protocol is the normal mode of operation, where the protocol type is known and
many tags are expected to pass through the readers.
Interactive Read Mode
TBD
Autonomous Read Mode
3
When the reader is in autonomous mode, the reader is placed under the control of its two
sensing inputs, which will most likely be in the form of photo sensors, ground loop
sensors, weight triggering mechanism or simple remote command. Upon receiving the
sensing input, the reader will switch to a pre-programmed single-protocol, multi-protocol
and in the case of a conveyor installation, fast-read mode and start reading functions.
Upon intercept of a RFID tag, the reader will automatically output the tag ID and after a
